CeraLink Capacitors
Introduction
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 (LP series) or which can be combined modularly to
form capacitors with higher capacitance values (FA and SP series).
