Features

4.3±0.3

CFULB_A series ceramic filters are miniature, high

performance ceramic filters composed of piezoelectric

elements connected in a ladder form.

These filters, with only 6.3mm high, are 65% the

volume of conventional types. (CFULA455K_A series)

They are well suited for miniaturizing various kinds

of communications equipment, pocket pagers, car

radios, cordless telephones and mobile telephones.

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.

(fn) means nominal center frequency 455kHz.

The order quantity should be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
