Seiko Instruments Inc. (SII) announcedthat 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.
Features:
－ Large discharge current and super rapid charging achieved by low internal resistance
－ Small leak current lower than 10 nA (CPX104 and CPZ104)
－ Reflowable, small and thin
