** 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.

The device characteristics and parameters in this data sheet can and do vary in different applications and actual device

performance may vary over time.

Users should verify actual device performance in their speciﬁc applications.
