Ceramic Filters (CERAFILr) for AM Receivers
Chip Type PFWCC Series
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.
Additionally its easy matching with IC helps create an
easy circuit design.
This is the most recommendable for portable radio with
small package. Especially, reflowable with SMD package.
s Features
1. Center frequency range between 450 and 470 kHz
are available standard tolerance of is
2 kHz.
2. For frequency synthesizers, center frequencies
of 450, 459 and 468 kHz are available standard
tolerance of
1 kHz.

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.

base (t=0.8mm)
s Notice (Soldering and Mounting)
Filter is soldered one time within the following
temperature condition and then being placed
in natural condition for 4 hours.
