!Note
SFPLA/CFWLA series for AM use is one of the most
suitable 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 suitable for car-stereo and
all band radio with high attenuation.

Area of 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.

• Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.

Part Number
Item
• Matching of CERAFILr SFPLA/CFULA/CFWLA series with IFT is decided
S(3)
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.
