The SCMQ14C474MRBA0 from Kyocera AVX is an Electrochemical Double-Layer Supercapacitor that is ideal for camera flash systems, GSM/GPRS pulse systems, remote metering, scanners, toys and games, UPS/industrial, wireless alarms, and energy harvesting applications. It has a capacitance of 0.47 F and a capacitance tolerance of ±20%. This supercapacitor has a voltage rating of 5 V and an equivalent series resistance (ESR) of 400 milli-ohms. It offers excellent pulse power handling characteristics with very high capacitance and low ESR. This RoHS-compliant supercapacitor can be used either individually or in conjunction with primary or secondary batteries, thereby resulting in extended backup time and longer battery life. It is available in a module that measures 14 x 6.3 mm.
