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.
For additional information, see application note on pages 323 and 324.
