- 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. 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 specifi c applications. ## **SRF0504 Series - Line FilterU8028A Serie Shielded Power Inductors** ## ~~**Soldering Prof le**~~ **==> picture [305 x 161] intentionally omitted <==** **----- Start of picture text -----**
