EMI/RFI TAPPED FILTER — ACF-B
Product Description
The ACF-B is an 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 flexibility for
adding components such as ferrite bead inductors for further wave shaping
Note: ACF-B is an upgraded version of the RCF-B series and is recommended for all new
designs
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 ACF-B filters exhibit almost pure RC
characteristics that extend effective filter performance to the GHz range and provide true broadband
attenuation.
