Lead Type SFPLA/CFWLA Series

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.
