Bourns’ EMI/RFI Filters Application Note.

601 Series - RC Network T-Filters

*RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011.

Specifications 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 specific applications.

General Description

Continual advances in digital IC technology are creating stringent demands on EMI/RFI

levels in equipment.

EMI/RFI low pass filters are required in personal computers, data terminals, test

equipment and process controllers for high frequency suppression into or out of

electronic equipment.
