PTCs as Charging Resistors

Posted on 01 January 2008

      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
