Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment
CERAFILr Plastic Case Miniaturized Type CFULB Series
CFULB series ceramic filters are miniature, high
performance ceramic filters composed of piezoelectric
elements connected in a ladder form.
These filters, only 6.3mm high, are 65% the
volume of conventional types.
They are well suited for miniaturizing various kinds
of communications equipment, pocket pagers, car
radios, cordless telephones and mobile telephones.
s Features
1. Miniature and high selectivity
2. A variety of bandwidths are available
3. Operating temperature range: -20 to +80 (degrees C)
Storage temperature range: -40 to +85 (degrees C)

Center frequency (fo) defined by the center of 6dB bandwidth.
(fn) means nominal center frequency 455kHz.
CFULB455K_series filters are 4-element ceramic filters and miniature versions of CFULA455K_series.
For safety purposes, connect the output of filters to the IF amplifier through a D.C. blocking capacitor. Avoid applying a direct current to the output of ceramic filters.
The order quantity should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
