Ceramic Filters (CERAFILr)/Ceramic Discriminators for Communications Equipment CERAFILr Plastic Case Group Delay Flat Type Miniaturized Type CFULB_Y Series Ceramic filter CFULB_Y series are miniature and high performance filters. These filters, with only 6.3mm high, are 65% the volume of conventional types (CFULA455K_Y series). Well suited for miniaturizing the communications equipment, especially for a cellular phone. s Features 1. Miniature, flat GDT characteristics. 2. Suitable for a cellular phone. 3. A variety of band width are available. 4. 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 CFULB455KB4Y-B0 CFULB455KC4Y-B0 CFULB455KD1Y-B0 CFULB455KE1Y-B0 CFULB455KF1Y-B0 CFULB455KG1Y-B0 Marking BY CY DY EY FY GY } MARKING EIAJ CODE Part Number Center Frequency (fo) (kHz) 6dB Bandwidth (kHz) Stop Bandwidth (kHz) Stop Band Attenuation (dB) Insertion Loss (dB) GDT Deviation ( µs) Input/Output Impedance (ohm) CFULB455KB4Y-B0 455.0 ±1.5kHz fn ±15.0 min. fn ±35.0 max.

[within fn ±3kHz] 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. CFULB455K_Y series filters are 4-element ceramic filters and miniature versions of CFULA455K_Y series. 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.
