CERAFILr (Filters/Traps/Discriminators) for Audio/Visual Equipment CERAFILr 455kHz SFPLA/CFWLA Series MARKING SFPLA/CFWLA series for AM use is one of the most recommendable intermediate filters, having such distinctive features as high selectivity, high stability, high attenuation, and adjustment-free operation. Additionally its easy matching with IC helps create an easy circuit design. This is the most recommendable for car-stereo and all band radio with high attenuation. 7.30.3 EIAJ CODE 2.70.3 (1) (3) SFPLA Series 0.60.1 1.20.5 Connection (1) : Input (2) : Ground (3) : Output 4.20.3 (2) 0.80.1 3.00.3 1.5max. 0.150.05 0.30.1 Features 7.00.3 8.00.3 (in mm) 3.30.5 11.00.5 7.50.5 EIAJ CODE 3.50.5 0.15 2.90.3 0.80.1 20 (2) (1) (5) 4.30.3 1.350.5 2.30.5 (4) (3) 0.60.1 2.60.3 2.90.3 2.9 2.9-- --0.3 1.20.5 CFWLA Series 1.5max. 7.00.5 MARKING Connection (1) : Input (2)(3)(4) : Ground (5) : Output (in mm) 2.00.3 Center Frequency (fo) (kHz) 6dB Bandwidth (kHz) Selectivity (+) (dB) Selectivity (-) (dB) Insertion Loss (dB) Input/Output Impedance (ohm) Element SFPLA450KJ1A-B0 450 1.0kHz fn2.0 min. 40 min.[fn+7.5kHz] 40 min.[fn-7.5kHz] 6.0 max. 2000 4 SFPLA450KH1A-B0 450 1.0kHz fn3.0 min. 40 min.[fn+9kHz] 40 min.[fn-9kHz] 6.0 max. 2000 4 CFWLA450KJFA-B0 450 (fn) fn2.0 min. 50 min.[fn+7.5kHz] 50 min.[fn-7.5kHz] 7.0 max. 2000 6 CFWLA450KHFA-B0 450 (fn) fn3.0 min. 50 min.[fn+9kHz] 50 min.[fn-9kHz] 6.0 max. 2000 6 Part Number Insertion Loss: at minimum loss point Center frequency (fo) is defined by the center of 6dB bandwidth. (fn) means nominal center frequency (450kHz). 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 should be an integral multiple of the "Minimum Quantity" shown in the package page. Recommended IFT (7x7) Type SFPLA/CFULA/CFWLA Item Winding Specification S(3) Test Circuit (1)--(2) (2)--(3) (4)--(6) 60T 125T 28T R1 (4)S Input Output Rg (2) (1) (6) RF R2 SSG (Bottom view) No load Qu 40 Tuning Capacitance 180pF * Matching of CERAFILrSFPLA/CFULA/CFWLA series with IFT is decided by the Qu of IFT and IFT secondary side impedance, |Z2|. Set the Qu at about 40 because a Qu value which is too high (e.g.,90) may produce ripple in the waveform. It is recommended to match the impedance of |Z2| with that of the CERAFILr.
