Fail-safe charging Self-protecting charging resistors based on PTC ceramic are suitable for smoothing capacitors in power supplies. In the event of a short circuit, they limit the currents to safe levels. By Dr. Stefan Benkhof, Product Marketing Manager PTC Thermistors, Epcos Ohmic resistors are generally employed to limit the current when [...]

Passive Components for Class D Amplifiers
Posted on 01 January 2008
Efficient Amplification Class D amplifiers have only made headway in audio technology over the last few years, even though this technology has existed since the middle of the last century. This development has been driven by the steady trend towards increasingly miniaturized and high performance devices. By Dr. Ing. Ralf Stiehler, Product [...]
