**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 (a) the Bromine (Br) content is 900 ppm or less; (b) the Chlorine (Cl) content is
900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.
