CERAFILr (Filters/Traps/Discriminators) for Audio/Visual Equipment
CERAFILr 455kHz for AM Stereo Wide Bandwidth Type SFPLA/CFWLA/CFULA Series
■ Features
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.

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.
