EMI/RFI T FILTER — RCF-A
Product Description
The RCF-A is an integrated EMI/RFI T Filter designed to Suppress EMI/RFI noise at I/O ports of
personal computers, peripherals, and communications equipment. Low pass resistor-capacitor filters
are effective at suppressing board-level EMI/RFI since the capacitor bypasses high frequency noise
directly to ground, thus eliminating it from the circuit. Discrete RC filters have limitations because of
their inherently higher parasitic inductance and capacitance, which create resonance and a notch-
like filter characteristic at lower frequencies.
Furthermore, these parasitic effects are highly variable and can turn discrete RC filters into tuned
circuits. Using proprietary semiconductor technology, Viking’s RCF-A filters exhibit almost pure RC
characteristics that extend effective filter performance to the GHz range and provide true broadband
attenuation.
