Seiko Instruments: nieuwe herschikbare condensatorchip met lage weerstand

CHIBA, Japan–(BUSINESS WIRE)– Seiko Instruments Inc. (SII) kondigt met blijdschap aan dat het zijn reeks Electric Double Layer Capacitor (EDLC)-chips uitbreidt. De producten zijn de CPX10080C104F (hierna CPX104), CPZ10080C104F (hierna CPZ104) en CPX10080C402F (hierna CPX402). CPX104 heeft met 0,5 ohm de laagste weerstand in zijn klasse. CPZ104, met een weerstand van 1,5 ohm, zorgt voor een zeer lage lekstroom van 10 nanoampère.

CPX104, CPZ104 en CPX402 zijn kleine, te herschikken EDLC-chips met zeer lage interne weerstand die een hoge ontlaadstroom van enkele honderden milliampère verwezenlijken. Daarnaast zorgt een luchtdicht, keramisch pakket voor betrouwbaarheid op de lange termijn.

Seiko Instruments: New Reflowable and Low Impedance Chip-Type Capacitor


CHIBA, Japan–(BUSINESS WIRE)–Seiko Instruments Inc. (SII) is pleased to announce that it is expanding its lineup of chip-type Electric Double Layer Capacitor (EDLC). The products are CPX10080C104F (hereinafter, “CPX104”), CPZ10080C104F (hereinafter, “CPZ104”) , and CPX10080C402F (hereinafter, “CPX402”). CPX104 has the lowest in class internal impedance of 0.5 ohm, and CPZ104 at 1.5 ohm, providing a very small leak current lower than 10 nA.

CPX104, CPZ104 and CPX402 are small reflowable, chip-type EDLCs that offer very low internal impedance, realizing high discharge current of about several hundred mA. Furthermore, a superior air-tight ceramic package assures its long term reliability.

SII succeeded in reducing leak current (self-discharge) to lower than 10 nA as well as the internal impedance for CPX104 and CPZ104. They can be sufficiently charged by several micro watts of slight electromotive force from energy harvesting devices. As for CPX402, it is a super rapid charging type EDLC which can increase voltage in a short period of time.

1. Large discharge current and super rapid charging achieved by low internal resistance
By reducing the internal impedance to 0.5 ohms/1.5 ohms, the new chip-type EDLCs allow discharge current of up to several hundreds of mAs. The super rapid charging type, CPX402 is able to charge within a few seconds.

2. Small leak current lower than 10 nA (CPX104 and CPZ104)
CPX104 and CPZ104 can be sufficiently charged with several micro watts from energy harvesting devices due to he small leak current.

3. Reflowable, small and thin
The chip-type design makes it possible to reflow when it is applied in the mass production. The size is 10.0mm x 8.0mm x 1.9mm.

[Suggested Applications]
1. Electric storage device for energy harvesting
2. Power source or electric storage for wireless sensor network, RFID tag, RF remote control for digital home electrical appliances
3. Power source or electric storage for contactless IC card, multi-functional IC card
4. Instant back-up for CPU or DRAM and power source for saving data on flash memory
5. Power backup of instantaneous battery detachment caused by mechanical shock
6. Battery power assist during instant large current draw

Available from August 2015.

Mass production will commence in July 2016.
