Ceramic Fuse > 469 Series
469 Series – 1206 Slo-Blo ® Fuse
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, typical in the Littelfuse Ceramic fuse
family, ensure high inrush current withstand capability.
