** Bourns follows the prevailing definition of “halogen free” in the industry. Bourns considers a product to be
MM
(INCHES)
“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.
