CERAFILr (Filters/Traps/Discriminators) for Audio/Visual Equipment
CERAFILr 455kHz 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 +-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.
