PFWCC 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.

■ Features
1. Center frequency range between 450 and 470 kHz
are available standard tolerance of +-2 kHz.
2. For frequency synthesizers, center frequencies
of 450, 459 and 468 kHz are available standard
tolerance of +-1 kHz.

Insertion Loss: at minimum loss point
Center frequency (fo) is defined by the center of 3dB bandwidth.
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.

The solder resist should be printed except for the land
pattern on the P.C.B..
The material of P.C.B. is the epoxy resin of glass fabric
