CFUM/CFWM455२Y SERIES

Ceramic filter CFUM/CFWM455२Y

Series are miniature and high-

performance 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.
