Panasonic has used conductive polymer technology to produce surface-mount aluminium electrolytic capacitors with 3mΩ max equivalent series resistance (ESR, 100kHz +20°C) in a 7.3 x 4.3 x 2.8mm package. The parts are intended as input or output capacitors on dc-dc converters. Maximum ripple current is 10.2A (100kHz +45°C – less at high temperature). Called the EEF-GY ...
