For FM-IF Tuners SFELF Series

SFELF10M7 series for FM-receivers are monolithic type

ceramic ﬁlters that use the thickness expander mode

of the piezoelectric ceramic.

As part of the environment protection program, the solder

for terminal plating and terminal-element connection

inside of the ceramic ﬁlter contain no lead (Pb).

c Features

1. Little dispersion of amplitude characteristics and

phase characteristics (G. D. T. characteristics)

2. The SFELF_G series is based on SFELF_FA00/GA00/

HA00, and it obtains high selectivity with low loss.

There is little dispersion of amplitude and GDT

characteristics, and low distortion rate can be

obtained.

3. The ﬂatness of GDT is inspected for all products.

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.
