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.

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.
