437 Series – 1206 Fast-Acting Fuse
Description
This 100% Lead-free, RoHS compliant and Halogen-free
fuse series has been designed specifically to provide over
current protection to circuits that see high working ambient
temperatures (up to 150C).
The general design ensures excellent temperature stability
and performance reliability.
In addition to this, the high It values typical of the
Littelfuse Ceramic Fuse family ensure high inrush current
withstand capability.
