Feedthru Filters from AVX Deliver EMI Suppression for Multi-Line Designs; AVX's Line of Feedthrus Ideal for LCD Filtering for Automotive Entertainment Centers.

MYRTLE BEACH, S.C. -- Providing automotive design engineers with significant noise reduction in digital circuits up to 5 GHz, AVX Corporation (NYSE:AVX) 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."

AVX's line of feedthru filters is ideal for applications requiring EMI suppression, broadband I/O filtering, LCD filtering, digital to RF interface filtering and VCC power line conditioning. Additional benefits of the multi-element array package are reduced placement costs, reduced component counts and PCB space savings. The W2F4/W3F4 Series can be used to meet MIL-STD-461E and SAE radiated and conducted emission requirements.

The W2F4/W3F4 Series is available in voltage ratings of 25V, 50V and 100V and features DC resistance ratings of less than 0.6 OMEGA. The parts have a current rating of 300mA, a standard operating temperature range of -55C to +125C., and exhibit NP0 and X7R temperature characteristics. The EMI filters are available in standard tape and reel packaging, making the W2F4/W3F4 Series filters compatible with high-speed automated assembly equipment and wave and reflow soldering methods.

Pricing starts at $0.35 each for the W3F4 Series in the 1206 case size. Lead times are from stock to 8 weeks.
