CAP-XX Supercapacitors manage your power

CAP‐XX (LSE:CPX) is a world leader in the design and manufacture of thin, flat supercapacitors and energy management systems used in portable and small‐scale electronic devices, and to an increasing extent, in larger applications such as automotive and renewable energy. CAP-XX has also acquired the Murata supercapacitor production lines and will be offering the DMF, DMT and DMH seris. The unique feature of CAP‐XX supercapacitors is their very high power density and high energy storage capacity in a space‐efficient prismatic package. These attributes are essential in power‐hungry consumer and industrial electronics such as wireless sensors, location tracking, asset tracking, scanners, LED flash, e-ink display updates, solenoids and motors for valve activation, locks  or drug delivery such as insulin injection. The CAP-XX range of large cylindrical cells deliver similar benefits in automotive and other transportation applications. Visit us at booth 943 in the Energy Harvesting Pavilion and come to Pierre Mars's tutorial on using supercapacitors with energy harvesters on Mon June 22 in Symposium 2 on Implementing Energy Harvsting.

  • DMF, DMT, DMH Series Supercapacitors
    CAP-XX Supercapacitors that are identical to and replace Murata DMF 1F, DMF 470mF, DMT 470mF, DMT220mF and DMH 0.4mm thin supercapacitors. DMF are very low ESR high power 5.5V while DMT series are low ESR, 4.2V, very long life parts that operate at 85C....

  • The DMF, DMT and DMH supercapacitors are thin prsmatic parts, previously manufactured by Murata who licensed the technology from CAP-XX. CAP-XX has acquired the Murata production lines and will be producing these products.

    The DMF3Z5R5H474M3DTA0 is 5.5V, 470mF, 45mOhm, 21 x 14 x 3.2mm supercapacitor. The DMF4B5R5G105M3DTA0 is 5.5V, 1F, 40mOhm, 40 x 14 x 3.7mm. These parts operate from -40C to +70C and are ideal to provide pulse power and ride through power interruptions for wireless sensors, data transmission, PDA's, solenoid activation or motor drive for valves, locks, drug delivery such as insulin injection, e-ink displays, asset tracking where a small, sleek, thin form factor is required. They are ideal power buffers to enable micro energy harvesters and coin cells to power these applications that have very low average power but peak power well beyond the capability of these energy sources. Power delivery at -40C is 55% of room temp power, so they are suitable for applications subjected to outdoor winter temperatures. They also have very low leakage current ~1uA so battery or harvester energy is not drained.

    The DMT334R2S474M3DTA0 is 4.2V, 470mF, 130mOhms, 21 x 14 x 3.5mm supercapacitor. The DMT3N4R2U224M3DTA0 is 4.2V, 220mF, 300mOhms. 21 x 14 x 2.2mm. These parts are very long life and operate from -40C to +85C. After 1 years' continuous operation at 4.2V, 70C, the C loss is only 30% and ESR rise only 20%. These parts are ideal to support automatic meter reading applications or building sensor applications that require up to 15 year life. The leakage current for these parts will settle to ~1uA so are not a significant drain on the battery energy. The DMT series are also ideal for power backup in SSDs that use cache memory. Updating a word in flash memory requires an entire page to be erased and re-written. To increase throughput, writes are cached in RAM. If there is a power interruption and the cache RAM data is lost, then the SSD is corrupted and cannot be recovered. In the case of power loss, a supercapacitor stores sufficient energy and delivers the power required for the SSD to flush the cache and gracefully shut down preserving integrity. The electronics in an SSD can be hot for sustained periods. For this reason, the DMT series, which has 5 year life at continuous operation at 4.2V, 70C is ideal to for SSD power backup.

    The DMH part is 2 individual cells in a 20mm x 20mm x 0.4mm package. When connected in series the 2 cells are a 4.5V, 35mF, 300mOhm supercapacitor, when connected in parallel a 2.3V, 150mF, 75mOhm supercapacitor. The thin formfactor makes the DMH ideal for smart credit card applications, in wearables, anywhere thinness is paramount. The DMH part will be available for production in mid 2021 but limited samples are available now.

  • G and H series prismatic supercapacitors
    CAP-XX ultra-low ESR prismatic supercaps offer a wide product range from 90mF - 2.4F, 1-3.9mm thick with 4 footprints and 2 ranges, G & H: dual cell modules are 5V, -40C to70C & 5.5V, -40C to 85C respectively, also available as 2.5V / 2.75V single cells....

  • CAP-XX G & H thin prismatic supercapacitors are ultra-low ESR product ranges suitable for peak power delivery and to provide backup power in case of interruptions. They offer a very wide range of parts so there will be an option tailored to your needs. The G series is 2.5V/cell, and operates from -40C to +70C while the H series is 2.75V/cell and operates from -40C to +85C. Capacitance ranges from 170mF/cell to 2.4F/cell. There are 4 footprints: “S” 39.5mm x 17.5mm, “W” 28.5mm x 17.5mm, “A” 20mm x 18mm including terminals which sits perfectly over a 20mm diameter coin cell such as a CR2032, and “Z” 20mm x 15mm including terminals which is a good fit for USB applications. The ranges are available as dual cell modules suitable for most batteries and electronics (5V or 5.5V) or single cells which are a thinner lower cost option for lower voltage electronics. Dual cell modules require cell balancing while single cells do not. The G series has lower ESR so delivers higher power. Thickness ranges from 1mm for a single cell to 3.9mm for a 1.2F dual cell part. Leakage current is ~1uA/F (so typically 1uA for a 1F cell, 0.5uA for a 0.5F/cell). Their ultra-low ESR and leakage current make them an ideal power puffer between a low power energy source such as a coin cell or micro-energy harvester and a high power load such as data transmission over NB IoT or LTE CAT M1. Consider a data transmission that requires 1W for 100ms every 10 mins. Then the average power = 167uW. The energy harvester or battery can charge the supercapacitor at ~170uW and the supercapacitor delivers the 1W effortlessly. Peak power for a 1 time pulse is 100W and the max power density in these ranges of supercapacitors is 160KW/L. The low leakage current means power from an energy harvester that may only provide 10’s of uA is not wasted. Similarly, 1uA leakage current only draws 8.8mAh/year from a battery, or ~4% of the 240mAh typical capacity of a CR2032 coin cell.

    ESR at -40C is only 2 – 2.5 x ESR at room temperature so these supercapacitors deliver very high power in North American and Northern European winters.

    Typical applications include providing peak power for data collection and transmission in wireless sensors; condition monitoring of rotating machines, railway rolling stock, structures such as bridges and dams, using a vibration transducer to charge a supercapacitor which powers capture and reporting of the vibration spectrum or strain & displacement readings, GPS acquisition and transmitting location for asset and location tracking; a temporary energy store charged by RF energy harvesting for active RFID; powering solenoids or motors for locks and valves, setting the lock or valve in a safe state in case of power loss; powering a vibration motor for haptic feedback; POS terminals, PDAs, Scanners to provide peak power for data transmission or LED illumination for scanning, and provide power backup in case the terminal is dropped and the battery contact briefly breaks; providing power backup for battery hotswap; providing peak power for data transmission in smart meters that typically use high energy Lithium Thionyl Chloride batteries that have very poor power delivery, particularly in cold temperatures; and automotive applications including peak power for data transmission in key fobs with a coin cell, providing distributed peak power with a supercapacitor located at the load such as a blinker or door lock solenoid – the wiring harness can now be sized for average power saving weight and cost, stabilising the vehicle voltage rail during sags, e.g. from engine cranking, for functions such as GPS, DVR, other instrumentation and entertainment.

    These supercapacitor ranges are perfect for when space is constrained and / or a sleek industrial design is required.

  • CAP-XX Small Cylindrical Supercapacitor Cells 2.7V
    Wide range of cylindrical supercapacitor cells, 3 product ranges:
    GY12R7: 2.7V, -40C to +65C, 1F -100F, radial leads
    HY12R7: 2.7V, -40C to +65C, 85C at 2.5V, 1F - 50F, radial leads
    GY12R7 low ESR, 2.7V, -40C to +65C, 1F - 850F, radial leads or solder tabs
    ...

  • CAP-XX offer 3 ranges of 2.7V cylindrical cells that are cost effective and meet needs from energy storage to pulse power delivery.

    The GY12R7 range operates from 0V - 2.7V, -40C to +65C. They are radial lead parts from 1F, 240mOhms – 100F, 15mOhms. They are also available as dual cell modules rated at 5.5V, GY25R5 series, with the option of resistor or active balancing. Cells range from 6.3mm dia x 12mm long to 18mm dia x 60mm long.

    The HY12R7 range operates from 0V – 2.7V, -40C to +65C, and can operate up to +85C when derated to 2.5V/cell.They are radial lead parts from 1F, 180mOhms – 50F, 23mOhms. They are also available as dual cell modules rated at 5.5V, 65C, HY25R5 series or to 5V at 85C. Cells range from 8mm dia x 12mm long to 18mm dia x 40mm long.

    The GY12R7 low ESR range operates from 0V – 2.7V, -40C to +65C ranging from 1F, 120mOhms – 850F, 0.5mOhms. Parts up to 50F have radial leads while larger, lower ESR, higher current parts have solder tabs or lugs. Parts up to 50F are available as dual cell modules rated as

    These ranges provide excellent peak power support for cold temperature operation where batteries struggle with ESR at -40C approximately 2x – 5x room temperature ESR, depending on the part.

    Typical equilibrium leakage current for all these ranges settles to ~1uA/F, so ~1uA for the 1F cells to ~100uA for the 100F cells. This low ESR and low leakage current makes them an ideal power buffer between a low power energy source such as a Lithium Thionyl Chloride battery or an energy harvester and a high peak power load such as RF transmission. A typical Lithium Thionyl Chloride battery is in the order of ~10Ah capacity. A 5F module comprising of 2 x 10F cells will draw ~10uA leakage current or 88mAh per year or ~0.9% of the capacity of a 10Ah battery. Similarly a 10F cell only loses ~1% of power from a solar cell providing ~1mA. These larger cells which are very cost effective are suitable where space is not constrained and / or applications which require high energy storage to power applications with extended duration, e.g. 10s of seconds to register with a WiFi or cellular network, or for when ambient energy may not be available for extended periods, such as solar cells overnight.

    Typical applications where space is not at a premium and these cells can be accommodated include smart meters which use high energy Lithium Thionyl Chloride batteries that have very poor power delivery, particularly in cold temperatures; providing peak power for GPS acquisition and transmitting location for asset and location tracking for heavy machinery, agricultural equipment, rolling stock, containers, vehicles etc.; industrial control and condition monitoring, for example using a vibration transducer to charge a supercapacitor which powers capture and reporting of the vibration spectrum or strain & displacement readings; powering solenoids or motors for locks and valves, setting the lock or valve in a safe state in case of power loss; in automotive applications to provide distributed peak power where there is space such as in a door cavity, tail light assembly, or dashboard, with a supercapacitor located at the load such as a blinker or door lock solenoid – the wiring harness can now be sized for average power saving weight and cost, and the supercapacitor can stabilise the vehicle voltage rail for functions such as GPS, DVR, other instrumentation and entertainment during sags, e.g. from engine cranking.

    All these applications require long life. CAP-XX cells have been extensively tested for over 10,000hrs. After 10 years at 2.5V, 25 deg C, capacitance loss will be ~30% and ESR rise will be ~50%, depending on the part. Life is not an arbitrary C loss such as 30% or increase in ESR such as 100% - it is when the C and ESR of a supercapacitor no longer support the application. Life can be lengthened by starting with a higher C, lower ESR supercapacitor. CAP-XX can assist to ensure you select the best supercapacitor to meet your needs.

  • CAP-XX Small Cylindrical Cells 3V
    Cylindrical supercapacitor 3V cells:
    GY13R0: 3V, -40C to +65C, 1F -50F, radial leads
    Designed to support 3V batteries and 3V electronics
    ...

  • Many primary batteries are 3V and much electronics will operate below 3V, often to 1.8V or less. The simplest way to support a 3V battery is to place a 3V supercapacitor cell across it to provide peak power and / or backup power support. The application circuit needs to operate at a lower voltage, e.g. 2.5V or 1.8V so the supercapacitor has headroom to discharge while supporting the application. If using standard 2.7V cells, then you need either a regulator to step the battery voltage down to 2.7V, or a dual cell module which will require a balancing circuit. Either option incurs extra cost and space. 3V cells are the best solution for these applications. 3V cells are also preferable for higher voltage modules, since fewer cells are required in series to attain your desired voltage. As an example, 18 x 2.7V cells are required for a 48V module, but only 16 x 3V cells are required.

    The GY13R0 range operates from 0V – 3.0V, -40C to +65C. They are radial lead parts from 1F, 180mOhms – 50F, 18mOhms. Cells range from 8mm dia x 12mm long to 18mm dia x 40mm long. Like the G12R7 range, these cells have excellent life and provide excellent peak power support in extreme cold with ESR at -40C ~ 2 x room temperature ESR. Typical equilibrium leakage current for the 3V range is ~1uA/F, so ~1uA for the 1F cells to ~50uA for the 50F cells. This low leakage current means they do not draw excessive charge from a 3V battery, e.g. a CR2450 has 620mAh capacity, so a 1F 3V cell will draw 8.8mAh over a year, or only ~1.4% of the CR2450’s capacity.

    Typical applications for these cells are the same as for the small 2.7V cylindrical cell range, but where the energy source is at 3V.
