Ceramic Multilayer Capacitors in HF SMPS Applications
Written By: John Prymak
Abstract:
There has been an explosion of interest in the use of ceramic capacitors for high frequency power conversion applications. This interest is compounded with new designs striving for higher frequencies, smaller sizes and greater efficiencies. This application is an ongoing and mutual development of ceramic values, processes and sizes that were never realized prior to this application. In more and more cases, the ceramic capacitor is dictated by performance requirements never attainable in the previous styles of electrolytic and tantalum.
