SFPCA series for AM use is one of the most
recommendable intermediate filters, having such
distinctive features as high selectivity, high
stability and adjustment-free operation.
Additionally its easy matching with IC helps create an
easy circuit design.
1. The filters are mountable by automatic placers
2. The filters are wide bandwidth and high

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.
