* RoHS Directive 2002/95/EC Jan 27, 2003 including Annex.
** 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.
