Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment CERAFILr Plastic Case General Use CFULA_A Series CFULA_A series are high selectivity ceramic filters, which consist of 4 ceramic elements connected in a ladder form. Most suitable for digital communications and cellular phones because of their improved GDT characteristics. s Features 1. High selectivity. 2. A variety of bandwidth available. 3. Excellent GDT characteristics are available within pass bandwidth. 4. Easily mounted on a printed circuit board 5. Operating temperature range : -20 to +80 (degree C) Storage temperature range : -40 to +85 (degree C) 0.8 ±0.1 0.6 ±0.1 1.2 ±0.5 8.0 ±0.3 3.3 ±0.5 2.7 ±0.3 (1) (2) (3) 0.15 ±0.05 Connection (1) : Input (2) : Ground (3) : Output (in mm) Type CFULA455KB2A-B0 CFULA455KC2A-B0 CFULA455KD4A-B0 CFULA455KE4A-B0 CFULA455KF4A-B0 CFULA455KG1A-B0 CFULA455KH1A-B0 Marking B C D E F G HT MARKING EIAJ CODE Part Number Center Frequency (fo) (kHz) 6dB Bandwidth (kHz) Stop Bandwidth (kHz) Stop Band Attenuation (dB) Insertion Loss (dB) Input/Output Impedance (ohm) CFULA455KB2A-B0 455.0 ±2.0kHz fn ±15.0 min. fn ±30.0 max.

[at minimum loss point] 2000 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. s Test Circuit E1 R1 Rg S.S.G. 0dBm R2 E2 RF Voltmeter Connection (1) : Input (2) : Ground (3) : Output (1) (2) (3) Rg+R1=R2=Input/Output Impedance Please read rating and !CAUTION (for storage and operating, rating, soldering and mounting, handling) in this PDF catalog to prevent smoking and/or burning, etc. This catalog has only typical specifications.
