11 / 78 page Ceramic Filters (CERAFIL r) for Communications Equipment CERAFIL r kHz SMD Type CFUKG_X Series The CFUKG_X series is comprised of 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. c 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 E to H. 5. Operating temperature range: -20 to +80 (°C) Storage temperature range: -40 to +85 (°C) 1.5±0.3 3.0±0.3 1.0±0.1 4.0±0.3 C0.5 1.2±0.1 1.0±0.1 (in mm) Connection (1): Input (2): Output (3): Ground 1.0±0.3 1.0±0.3 1.5±0.3 6.0±0.3 (1) (2) (3) MARKING EIAJ CODE Part Number Center Frequency (fo) (kHz) 6dB Bandwidth (kHz) Stop Bandwidth (kHz) Stop Band Attenuation (dB) Insertion Loss (dB) Ripple (dB) GDT Deviation (µs) Input/Output Impedance (ohm) CFUKG455KE4X-R0 455 ±1.5kHz fn±7.5 min. fn±17.5 max.

(fn) means nominal center frequency 455kHz. For safety purposes, connect the output of filters to the IF amplifier through a DC 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.
