** 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.
Specifications are subject to change without notice.
Customers should verify actual device performance in their specific applications.
