Matching Conditions
When using ceramic filters, it is most important to
match the input/output load to impedance 330 ohm
(only SFELA10M7DF00-B0 is 470 ohm matching).
Waveform symmetry is damaged when reactance
is added to the input/output load.
Two ceramic filters directly connected can be used
for high selelctivity. For reducing waveform
variation, it is recommended to input a buffer AMP
between ceramic filters.
The SFELA10M7 and SFTLA10M7 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.
