Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment CERAFILr Plastic Case Miniaturized Type CFULB_A Series CFULB_A series ceramic filters are miniature, high performance ceramic filters composed of piezoelectric elements connected in a ladder form. These filters, with only 6.3mm high, are 65% the volume of conventional types. (CFULA455K_A series) They are well suited for miniaturizing various kinds of communications equipment, pocket pagers, car radios, cordless telephones and mobile telephones. s Features 1. Miniature and high selectivity. 2. A variety of bandwidths are available. 3. Operating temperature range : -20 to +80 (degree C) Storage temperature range : -40 to +85 (degree C) 1.8 ±0.3 2.4 ±0.3 6.5 ±0.3 0.8 ±0.3 0.5 ±0.1 0.7 ±0.1 0.7 ±0.3 (1) (2) (3) (4) 0.15 ±0.05 Connection (1) : Input (2) : Output (3) : Ground (4) (in mm) Type CFULB455KB2A-B0 CFULB455KC2A-B0 CFULB455KD4A-B0 CFULB455KE4A-B0 CFULB455KF4A-B0 CFULB455KG1A-B0 CFULB455KH1A-B0 CFULB455KJ1A-B0 Marking 55B 55C 55D 55E 55F 55G 55H 55I } 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) CFULB455KB2A-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) : Output (3)(4) :Ground (1) (2) (3) (4) 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.
