SFPLA/CFWLA series for AM use is one of the most
suitable intermediate ?lters, 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.

Center frequency (fo) is de?ned by the center of 6dB bandwidth.
(fn) means nominal center frequency (450kHz).
For safety purposes, connect the output of ?lters to the IF ampli?er through a D.C. blocking capacitor. Avoid applying a direct current to the output of ceramic ?lters.
The order quantity should be an integral multiple of the "Minimum Quantity" shown in the package page.
