Compact and high capacitance ceramic capacitors from TDK electronics. Link here (PDF)
CeraLink is a family of very compact capacitors for stabilizing voltages in the DC link. They are therefore suitable for use as either snubber or DC link capacitors. These products are based on PLZT ceramics and are designed to provide engineers with compact components optimized for fast switching converters, converters with very tight space requirements and converters that need to withstand high operating temperatures. The basic component is a ceramic chip which either is manufactured with lead frames or which can be combined modularly to form capacitors with higher capacitance values.
Development and improvement of ceramic multilayer capacitors in high frequency power supply filtering, a technical note from AVX. Link here (PDF)
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.
