sales representatives or product engineers before ordering.
!Note
SFELF10M7 series for FM-receivers are monolithic type
ceramic filters which use the thickness expander mode
of the piezoelectric ceramic.
As part of the environment protection activity, solder
for terminal plating and terminal-element connection
inside of ceramic filter contain no lead (Pb).
These types have lower spurious response compared
to the standard filters.

Area of Attenuation: [within 20dB]
Area of Spurious Attenuation: [within 9MHz to 12MHz], SFELF10M7KAB0-B0: [within 9MHz to fo/fo to 12MHz]
Area of Insertion Loss: at minimum loss point
Center frequency (fo) 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.
