**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;
Specifi cations are subject to change without notice.
Customers should verify actual device performance in their specifi c applications.
