Feedthru Filters W2F4 / W3F4 Series EMI Filtering, Broadband Filtering, LCD Filtering GENERAL DESCRIPTION W3F4 Series Available in a 4-Element 0508 and 0612 Feedthru Array package, AVXs line of Feedthrus 0612 is an ideal choice for EMI suppression, broadband I/O filtering, LCD filtering and V power cc line conditioning. The unique construction of the Feedthru capacitor provides low parallel inductance and offers excellent decoupling capability for all high di/dt environments and provides significant noise reduction in digital circuits up to 5 GHz. A range of filtering characteristics is available. The Feedthru Array contains four elements with a common ground connection, making it an ideal choice for multi-line designs. Additional benefits of the multi-element array package are reduced placement costs, reduced component counts and PCB space savings. Feedthru filters can be used to meet IEC, MIL-STD- 461E, FCC, and SAE radiated and conducted emission requirements.
