DESCRIPTION:
The CENTRAL SEMICONDUCTOR CMMR1U Series
are high quality 1.0 Amp Surface Mount Silicon
Rectifiers, well constructed, highly reliable components
designed for use in all types of commercial, industrial,
entertainment, computer, and automotive applications.
The SOD-123F case occupies 58% less board space
than the SMA, with a 67% lower profile.
