CERAFIL Low-loss Type
SFELA10M7 series for FM-receivers are monolithic type
ceramic filters which use the energy trapped thickness
vibration-mode of the piezoelectric ceramic.
I
Features
1. Insertion loss is 1 to 1.5dB lower than
conventional products. This 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.
