CERAFIL Standard Lead 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. These miniature filters have high mechanical
strength.
2. Low loss, favorable waveform symmetry, and high
selectivity.
3. Various band widths are available for applications
in wide to narrow bands.
4. Small dispersion and stable characteristics.
5. Change in center frequency is typically within
±
30ppm/(degree C) at -20 to +80 (degree C).
6. High reliability.
