App note: CeraLinkĀ® Capacitors


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.

App note: Microphone specifications explained


All about MEMS microphone from TDK Invensense. Link here (PDF)

A MEMS microphone IC is unique among InvenSense, Inc., products in that its input is an acoustic pressure wave. For this reason, some specifications included in the data sheets for these parts may not be familiar, or familiar specifications may be applied in unfamiliar ways. This application note explains the specifications and terms found in MEMS microphone data sheets so that the microphone can be appropriately designed into a system.
