EMI Suppression Effect / Description
Ringing is caused on the signal waveform.
Such ringing contains several hundred MHz harmonic components and generates noise.

Comparing initial waveform, ringing is suppressed a little.
However there still remains high level waveform distortion.

BLM18R has excellent performance for noise suppression and waveform distortion suppression.
BLM18R suppresses drastically not only spectrum level in more than 100MHz range but waveform distortion.
