New feedthru filters from AVX
Nov 05, 2004
AVX Corporation has developed a new series of feedthru filters for data lines for automotive entertainment systems. Designated the W2F4 and W3F4 Series, the feedthru array contains four elements with a common ground connection, making it an ideal choice for multi-line designs. The unique construction of the feedthru capacitor provides low parallel inductance and offers excellent broadband EMI attenuation for all circuitry in need of passing SAE, FCC and IEC EMC requirements. These devices are available in a 4-element 0508 and 0612 feedthru array package. Applications for the W2F4/W3F4 Series filters include data lines to dashboard and diagnostic units, as well as on RGB lines to LCD displays within entertainment centers such as DVD players and GPS units. "Today's high speed miniaturized semiconductors have made EMI issues a key design consideration for automotive designers," said Ron Demcko, AVX Applications Engineering Manager. "By optimizing board layout with large power and ground planes, the use of feedthru filters is an inexpensive way to achieve excellent EMI compliance." Pricing starts at $0.35 each for the W3F4 Series in the 1206 case size. Lead times are from stock to 8 weeks. For more information visit www.avx.com.
