!Effect of Noise Suppression by NFR21G
NFR21G is effective even if ground line is not stable enough
due to its distributed constant circuit structure.

The standard type chip EMIFILr is effective on stable
ground lines.
NFR21G has some advantages to standard type
EMIFILr on stable ground lines.
The standard type EMIFILr loses efficiency on poor
ground lines.
NFR21G is effective even on poor ground lines because
of its distributed constant circuit structure and unique
system to limit rush current.
