* RoHS Directive 2002/95/EC Jan 27, 2003 including Annex.
** 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.
Specifi cations are subject to change without notice.
Customers should verify actual device performance in their specifi c applications.
