!FEATURES
SFPS/CFWS Series :
wide band, high selectivity, low loss.
CFUS-Y/CFWS-Y Series :
wide band, flat group delay time (GDT) characteristics. (The
frequency fidelity in the high sound area of an AM stereo will
be improved.)

) : Typ. value
"The standard center frequency (f0) tolerance is T1 kHz.
"The recommended IFT specifications are the same as those for the SFPS 450 H/CFWS 450 HT. Set the Qu at approximately 40. If Qu is too
high, ripple will be produced in the waveform, which will narrow the band width.
"Products with other band widths are also available :
