EMI/RFI T FILTER — ACF-A
Product Description
The ACF-A is an integrated EMI/RFI T-filter designed to suppress EMI/RFI noise in computers,
peripherals, data and telecom equipment, and wireless products. The ACF-A has a symmetrical design
ideal for filtering signal waveforms traveling in opposite directions such as on a bi-directional bus.
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-A filters exhibit almost pure RC characteristics that extend effective filter
performances to the GHz range and provide true broadband attenuation.
