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.
