FILTERS FOR COMMUNICATIONS EQUIPMENT
MINIATURE, G.D.T. FLAT TYPE
CFUM/CFWM455Y SERIES
Ceramic filter CFUM/CFWM455Y
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.
FEATURES
s Miniature, flat G.D.T. characteristics
s Suitable for a cellular phone
s A variety of bandwidths are
available.
s Operating temperature range:
–20°C to +80°C
Storage temperature range:
–40°C to +85°C
s Available for 450kHz and 455kHz
