CERAFILr (Filters/Traps/Discriminators) for Audio/Visual Equipment
CERAFILr 10.7MHz Wide Bandwidth Type
SFELA10M7 series for FM-receivers are monolithic type
ceramic filters which use the thickness expander mode
of the piezoelectric ceramic.
■ Features
Realizes widerband characteristics not obtained by
conventional ceramic filters.
