!Note
Ceramic filter CFULB_Y series are miniature and high
performance filters. These filters, only 6.3mm
high, are 65% the volume of conventional types.
Well suited for miniaturizing communications
equipment, especially for a cellular phone.
1. Miniature, flat GDT characteristics
2. Suitable for a cellular phone
3. A variety of bandwidths are available.
4. Operating temperature range: -20 to +80 (degrees C)

Center frequency (fo) defined by the center of 6dB bandwidth.
(fn) means nominal center frequency 455kHz.
CFULB455K_Y series filters are 4-element ceramic filters and miniature versions of CFULA455K_Y 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.
