CERAFIL r (CERAFIL r 10.7MHz) for Audio/Visual Equipment
Narrow Bandwidth Type SFELF Series
7.0±2.0
P50E.pdf
Sep.19,2012
c Features
SFELF10M7LFTA/KAH0 series realizes narrower band
characteristics not obtained by conventional ceramic
?lters. Besides, low spurious and temperature
characteristics are stable. This series is suitable for
European car-audio or AM upconversion use that
needs stable narrow band characteristics.
As part of the environment protection program, the solder

For safety purposes, connect the output of ?lters to the IF ampli?er through a D.C. blocking capacitor. Avoid applying a direct current to the output of ceramic ?lters.
The order quantity should be an integral multiple of the "Minimum Quantity" shown in the package page.
