FILTERS FOR COMMUNICATIONS EQUIPMENT RESIN MOLDED –HIGHLY SELECTIVE 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.
