Applications

■ Noise suppression ■ Personal computers ■ Display panels SRF2012A Series - Common Mode Chip Inductors * 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.
