EMI Feedthru Filters Combine Caps And Coils

Combining capacitor and inductor elements in a single, distributed constant circuit filter, the W2F series EMI feed-through filters provide EMI noise suppression, broadband I/O filtering, or VCC power-line conditioning. Claiming to be the industry's smallest filters, they are rated at 100V and 300 mA with capacitance ratings from 22 pF to 47,000 pF. Typical attenuation options range from 30 dB to 60 dB across user-selected frequency spectrums and standard operating temperature is from -55ûC to 125ûC. Available in a 1206-size case, as well as a four-element 1206 feed-through array, typical prices range from $0.05 to $0.07 each/100,000. AVX CORP., Myrtle Beach, SC. (843) 448-9411.
