Description
RoHS
Pb
e3
The SMF series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
SMF package is 50% smaller in footprint when compare
to SMA package and deliverying one of the low height
profiles (1.1mm) in the industry.
