FILTERS
FOR COMMUNICATIONS EQUIPMENT
CFUCG/CFUCGX/SFGCG SERIES
The CFUCG455Series comprises small,
high performance, 4.0mm thin filters
consisting of 4 ceramic elements. Their
innovative construction is perfect for
shrinking mobile communication products
such as pocket pagers and cellular
phones.
In addition, CFUCG455X Series filters
exhibit an extremely flat G.D.T.
characteristic combined with a narrow
bandwidth. The filters are recommended
for narrow band digital communication
applications.
The SFGCG455Series filters exhibit an
extremely flat G.D.T. characteristic as
well, and are recommended for digital
communication applications and are
perfect in hand held cellular phones, etc.
FEATURES
s Mountable by automatic placers
s Can be reflow soldered and can
withstand washing
s 4.0mm maximum thickness, with small
mounting area (7.5 x 6.0mm2)
enabling flexible PCB design
s Bandwidth range from D to G
DIMENSIONS: mm
