Very low equivalent series resistance (ESR). Very low equivalent series inductance (ESL). Lower impedance at higher frequencies.
DC/AC Bias of MLCC Capacitors and its Temperature Dependence
WebFour MLCC types were included, two of which were flexible-termination MLCCs and two were standard-termination MLCCs. For each end-termination type, a group of MLCCs with precious metal electrodes (PME) made of silver-palladium and a group of MLCCs with base metal electrodes (BME) made of nickel were selected.
