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 150ºC.
The general design ensures excellent temperature stability
and performance reliability.
The high I²t values which are typical in the Littelfuse
Ceramic fuse family, ensure high inrush current withstand
capability.
