Silicon Capacitors

Introduction

Silicon capacitors are increasingly being used as an alternative to traditional ceramic, aluminium electrolytic and film capacitors. Silicon capacitors are attractive for various reasons including higher working voltages, smaller packages, lower ESR/ESL values and higher heat tolerance. Their most appealing characteristic is their very low equivalent series resistance (ESR) and equivalent series inductance (ESL) values. This results in a superior dynamic response to power fluctuations in short pulse applications, which are often encountered in high-frequency power electronics.
