CERAFIL Three-Elements Type SFTLA Series
SFTLA10M7 series for FM-receivers are monolithic type
ceramic filters which use the energy trapped thickness
vibration-mode of the piezoelectric ceramic.
I
Features
1. It has an excellent shape factor, and it is
possible to obtain 1.5 times more excellent
selectivity than SFELA10M7 series (by detuning
+-300 or 400kHz).
2. Good performance of spurious suppression.
3. Having the same terminal pitch as the SFELA10M7
series, it easily replaces that series.
4. By replacing two SFELA10M7 series filters with one
SFTLA10M7 filter,more compact sets can be made.
5. Well-suited for 1-chip ICs.
