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.
