In 2003 the European Union enacted the Reduction of Hazardous Substances Directive (RoHS). This legislation seeks to reduce the concentration of six substances from electrical and electronic equipment that falls within the instruction scope. These substances are:

		Lead
		Mercury
		Cadmium
		Hexavalent chromium
		Polybrominated biphenyls (PBB)
		Polybrominated diphenyl ethers (PBDE)

North Hills now manufactures RoHS compliant versions of our Wideband Transformers.  To order a RoHS compliant Wideband Transformer simply add the letters LF at the end of the model number. 

For example:  North Hills balun transformer 0300BB-LF is a RoHS compliant product.

The North Hills MIL-STD-1553 Data Bus Coupler product line is in a category exempt from the RoHS directive.

All RoHS compliant parts are interchangeable with their non-compliant predecessors.
