Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment
CERAFILr kHz SMD Type CFUKF Series
The CFUKF series is comprised of small, high performance,
thin (4.0mm) filters consisting of 4 ceramic elements.
The filters exhibit an extremely flat GDT
characteristic.
The filters are recommended for digital
communication applications and are perfect in hand
held cellular phones, etc.
s Features
1. The filters are mountable by automatic placers.
2. The filters can be reflow soldered and withstand
washing.
3. They are slim, at only 4.0mm maximum thickness,
and have a small mounting area (7.5x6.0mm)
enabling flexible PCB design.
4. The bandwidth ranges from A to E.
5. Operating temperature range: -20 to +80 (degrees C)
Storage temperature range: -40 to +85 (degrees C)

Center frequency (fo) defined by the center of 6dB bandwidth.
(fn) means nominal center frequency 455kHz.
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 shoud be an integral multiple of the "Minimum Quantity" shown in package page in this catalog.
