Low Loss Type 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. Insertion loss is 1 to 1.5dB lower than

conventional products. These types are useful for

elevating the sensitivity of sets.

2. Small dispersion and stable characteristics

3. Excellent shape factor of frequency response

4. Good waveform symmetry

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.
