!Note
!Note
The CFUCG_X series comprises small, high performance,
thin (4.0mm) filters consisting of 4 ceramic elements.
The filters exhibit an extremely flat GDT
characteristic combined with a narrow bandwidth.
The filters are recommended for narrow band digital
communication applications.
1. The filters are mountable by automatic placers.
2. The filters can be reflow soldered and withstand
3. They are slim, at only 4.0mm maximum thickness,
4. The bandwidth ranges from E to H.
5. Operating temperature range : -20 to +80 (degree C)

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.
