RoHS Compliance means conformity to EU Directive 2002/95/EC of 27 January 2003, on the restriction of the use of certain hazardous substances in electrical and electronic equipment. It restricts the use of the following six substances: lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ether. The maximum permitted concentrations are 0.1% or 1000 ppm (except for cadmium, which is limited to 0.01% or 100 ppm) by weight of homogeneous material. Powertron GmbH defines homogeneous materials as substances that cannot be mechanically disjointed into different materials. Examples of homogeneous materials are electroplated coatings, molding compounds, insulation sleeves, lead frame alloys, and bonding wires.

Powertron standard products conform with this regulation without exception and the RoHS mark is on every datasheet. Non-conforming devices for applications such as military, aviation, and automotive are available on request as custom products.
