match the input/output load to impedance 330 ohm
(SFELA10M7DF00-B0 is 470 ohm and
Waveform symmetry is damaged when reactance is added
to the input/output load.
for high selelctivity. For reducing waveform
variation, it is recommended to input a buffer AMP

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.
