SFT10.7MS3

FILTERS FOR FM APPLICATIONS–HIGHLY SELECTIVE, 3 ELEMENTS SFT MA/MS 10.7MHz The SFT 10.7 ceramic filters are single substrate, 3 element devices that offer 1.5 times more selectivity than the conventional SFE Series of filters. The improved spurious suppression of these filters eliminates the need for cascading multiple filtering devices; therefore, it is possible to design a more compact circuit board configuration. FEATURES s It has an excellent shape factor, and it is possible to obtain 1.5 times more excellent selectivity than SFE 10.7 Series (by detuning ±300 or 400kHz). s Good performance of spurious suppression. s Having the same terminal pitch as the SFE 10.7 Series, it easily replaces that series. s By replacing two SFE 10.7 Series filters with one SFT 10.7 filter, more compact sets can be made. s Well-suited for 1-chip ICs.
