*RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011. 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. *RoHS COMPLIANTVERSIONS AVAILABLE General Description Continual advances in digital IC technology are creating stringent demands on EMI/RFI levels in equipment. EMI/RFI low pass fi lters are required in personal computers, data terminals, test equipment and process controllers for high frequency suppression into or out of electronic equipment.
