Ceramic Filters (CERAFILr) for FM Receivers
CERAFILr For FM -IF Tuners
9.0 max.
SFELA10M7 series for FM-receivers are monolithic type
ceramic filters which use the energy trapped thickness
vibration-mode of the piezoelectric ceramic.

■ Features
1. Little dispersion of amplitude characteristics and
phase characteristics (G. D. T. characteristics).
2. The SFELA10M7G_X series has G. D. T characteristics
0.5±0.1
2.5±0.2 2.5±0.2
and is useful for obtaining low distortion.
SFELA10M7F_L series, in these ceramic filters,
being in harmony with flatness of G. D. T. ,
roundness of the amplitude and selectivity
characteristics, therefore, these ceramic filters
are suitable to high-grade stereo tuners. Even if
mismatching condition, they can keep little
distortion because of low Qm of ceramic material.
The SFELA10M7FA0G series is based on
SFELA10M7FA00/GA00/HA00, and it obtains high
selectivity with low loss.
