Ceramic filter CFWLB_Y series are miniature and
high-performance filters. These filters, with only
6.3mm high, are 67% the volume of conventional types
(CFWLA455K_Y series).
Well suited for miniaturizing the communications
equipment, especially for a cellular phone.

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.
CFWLB455K_Y series filters are 4-element ceramic filters and miniature versions of CFWLA455K_Y series.
