Overview
FILTERS FOR COMMUNICATIONS EQUIPMENT MINIATURE, G.
D.
T.
FLAT TYPE CFUM/CFWM455२Y SERIES Ceramic filter CFUM/CFWM455२Y Series are miniature and highperformance filters.
These filters, while only 6.
3mm high, are 60% the volume of conventional types (CFUS/CFWS Series).
Well suited for miniaturizing the communications equipment, especially for a cellular phone.
