In recent years, there have been remarkable increases in withstand voltage and capacitance in MLCCs (multilayer ceramic chip capacitors) for temperature compensation (type 1). In particular, even in fields where film capacitors have traditionally been used, resonance circuits for example, replacement with MLCC is now possible.

This article introduces some causes of and effective measures against acoustic noise in power inductors, which are main components in power circuits of devices such as DC-DC converters.

TDK’s chip varistors are ESD protection components that can solve various needs that are specific to audio lines. We shall now explain the various advantages providing the optimal solutions for the audio lines of smartphones.
