**Halogen free product is identified by a black housing color. Bourns follows the prevailing definition of “halogen free” in the industry.
Bourns considers a product to be “halogen free” if (a6 the Bromine (Br6 content is 9ꢀꢀ ppm or less; (b6 the Chlorine (Cl6 content is
9ꢀꢀ ppm or less; and (c6 the total Bromine (Br6 and Chlorine (Cl6 content is 15ꢀꢀ ppm or less.
