Feedthru Filters – W2F4/W3F4 Series

EMI Filtering, Broadband Filtering, LCD Filtering

GENERAL DESCRIPTION

Available in a 4-Element 0508 and 0612 Feedthru Array package, AVX’s

line of Feedthrus is an ideal choice for EMI suppression, broadband I/O

filtering, LCD filtering and Vcc power line conditioning. The unique con-

struction 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.
