Applications

■ DC/DC converters ■ Notebook computers ■ Digital video cameras ■ HDDs ■ Cell phones ■ Televisions, LCD displays SRN4018 Series - Semi-shielded Power Inductors * RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011. ** 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.
