601 Series - RC Networks T-Filters

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.
