Sec.)

Devices designed to carry out rated current for 4 hours minimum. It is recommended that

devices be operated continuously at no more than 80% rated current. See “Temperature

Rerating Curve”for additional rerating information.

Devices designed to be mounted with marking code facing up.

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 150ºC) and high inrush currents.

The general design ensures excellent temperature stability

and performance reliability.

This high I²t fuse series is designed to have ultra high inrush

current withstand capability to avoid nuisance fuse open.
