CFUM/CFWM 450/455kHz SERIES
The CFUM and CFWM lines
of ceramic filters are miniaturized
versions of the CFU/CFWS lines.
These ultra-miniature versions consume
approximately 40% less volume while
still offering the same high performance
filter characteristics available with the
CFU/CFWS lines. They are available in
450kHz and 455kHz versions.
