Cadmium-free trimpots

14 July 2004 Passive Components Surveillance

Murata says it is now mass producing cadmium-free cermet resistive materials, becoming the world's first potentiometer supplier to realise cadmium-free production of complete ranges. Previously, all trimmer potentiometers utilising cermet resistive materials for industrial use have contained a small amount of cadmium.

Murata already makes cadmium-free chip potentiometers (PVA3, PVS3) and some through-hole potentiometers (PV32, PVM6 and PV12). It has now introduced 10 new cadmium-free series of potentiometers: the PVG3, PVM4, PVG5, PV01, PVC6, PV34, PV37, PV23, PV22 and PV36.

These families meet the RoHS Directive, which requires that from 1 July 2006, new electrical and electronic equipment on the market does not contain mercury, cadmium, hexavalent chromium etc.
