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.
