SFPLA/CFWLA/CFULA 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. Especially, CFULA/CFWLA_Y series is the frequency fidelity in the high sound area of an AM stereo will be improved with wide band, flat group delay time characteristics. 0.30.1 Features 7.00.3 8.00.3 GDT 20sec.

(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. 62 P50E.pdf 03.4.16 catalog to prevent smoking and/or burning, Pleaseread readrating ratingand and!CAUTION !CAUTION(for (forstorage, storage,operating, operating,rating, rating,soldering, soldering,mounting mountingand andhandling) handling)ininthis thisPDF catalog to prevent smoking and/or burning, etc. etc. !Note *Please you are requested approvespecifications. our product specifications or to transact approval for product before ordering. *This Thiscatalog cataloghas hasonly onlytypical typicalspecifications. specificationsTherefore, because there is no space fortodetailed Therefore, please approvethe our productsheet specifications or specificaions transact the approval sheet for product specifications before ordering.

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.
