- ** Bourns follows the prevailing defi nition 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.
