T Filter Network
TFA SERIES
T Filter Network
T Filter networks are used for suppression of
EMI/RFI at low and high frequencies. The T filter ’s
symmetric design is useful for filtering bi-directional
signals. KOA’s T Filter networks offer exceptional
filtering capabilities at both low and high frequencies,
as well as exhibiting superior characteristics of
advanced thin film processing. This is of particular
significance in today’s high speed/high frequency
applications using advanced digital technology and
the overall increased use of RF products. A standard
8-filter channel network replaces expensive and
bulky discrete devices, saving real estate, increasing
board yields, increasing reliability and reducing
overall manufacturing costs.
