PFSLA/PFWLA 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 radios
with small package.
1. Center frequency range between 450 to 470 kHz
2. For frequency synthesizers, center frequencies

Insertion Loss: at minimum loss point
Center frequency (fo) is defined by the center of 3dB bandwidth.
The order quantity should be an integral multiple of the "Minimum Quantity" shown in the package page.
