EMI/RFI TAPPED FILTER — RCF-B
Product Description
The RCF-B are a series of integrated EMI/RFI Tapped filter designed to suppress EMI/RFI noise in
computers and peripherals, data and telecom equipment, and wireless devices. A single RC tapped
configuration is ideal for filtering signal waveforms on a unidirectional bus and provides some
flexibility for adding components such as ferrite bead inductors for further wave shaping.
Low pass resistor-capacitor filters are effective at suppressing board-level EMI/RFI since the
capacitor bypassed 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-B filters exhibit almost pure RC
characteristics that extend effective filter performance to the GHz range and provide true broadband
attenuation.
