Ceramic Filters (CERAFILr) for FM Receivers
CERAFILr Wider Band-width Type
7.0±2.0
SFELA10M7 Series for FM-receivers are monolithic type
ceramic filters which use the energy trapped thickness
vibration-mode of the piezoelectric ceramic.

1. Realizes wider or narrower band characteristics not
obtained by conventional ceramic filters.
2. Temperature characteristics are the best available,

the same as those of Murata's conventional ceramic
filters. Thus, even in the case of narrow band
filters, the center frequency is stable even if
temperature changes.
