AC04
Resonance between the internal
capacitance of the IC and the
inductance of the print pattern causes
waveform overshooting and
undershooting.
Ordinary capacitor filters have no
waveform distortion suppressing
capability, and they cannot suppress
disturbances in the waveforms.
The waveform distortion suppressing
function of NFR21G minimizes
disturbances of waveforms.
