601 Series - RC Network 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.
