FILTERS
FOR AM AND FM APPLICATIONS
CFZC/CFWC SERIES
The CFWC455CZ Series consist of 6
ceramic elements. The filters are
recommended for digital communication
applications and are perfect in hand
held cellular phones.
FEATURES
s The filters are mountable by
automatic placers.
s The filters can be reflow soldered.
s They are slim, at only 3.0mm
maximum thickness, and have a small
mounting area (11.5 x 7.5mm2)
enable flexible PCB design.
