** Bourns follows the prevailing de?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.

Speci?cations are subject to change without notice.

Customers should verify actual device performance in their speci?c applications.
