!MATCHING CONDITIONS
¡When using ceramic filters, it is most important to match
the input/output load to impedance 330(pure
resistance). Waveform symmetry is damaged when
reactance is added to the input/output load.
¡Two ceramic filters directly connected can be used for high
selectivity. For reducing waveform variation, it is recommended
to input a buffer AMP between ceramic filters.
No.P61E5.pdf 98.6.22
¡The SFE 10.7 and SFT 10.7 series are of input/output
symmetric structure so that in theory there is no
input/output directionality. Actual circuits may use different
input/output loading conditions (for example, mismatched
impedance) or capacitance load.
In such cases, the waveform will be a little changed by the
direction of the input/output of the ceramic filters.

3-element Type SFT10.7 Series
No.P61E5.pdf 98.6.22
!FEATURES
1. It has an excellent shape factor, and it is possible to
obtain 1.5 times more excellent selectivity than SFE 10.7
series(by detuningT300 or 400kHz).
2. Good performance of spurious suppression.
3. Having the same terminal pitch as the SFE 10.7 series, it
easily replaces that series.
4. By replacing two SFE 10.7 series filters with one SFT
10.7 filter,more compact sets can be made.
5. Well-suited for 1-chip ICs.

¡Input/output matching impedance : 330
¡SFT10.7 series is good to replace with
¡SFE10.7 series because of its higher selectivity.
