Description
The 469 Series is a 100% Lead-free, RoHS compliant and
Halogen-free fuse series designed specifically to provide
over-current protection to circuits that operate under high
working ambient temperature up to 150C.
The general design ensures excellent temperature stability
and performance reliability.
The high It values which are typical in the Littelfuse
Ceramic fuse family, ensure high inrush current withstand
capability.
