Surface Mount Fuses

469 Series

Ceramic Fuse > 469 Series

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.

Electrical Specifications by Item

1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting

Rating tested at rated voltage with time constant < 0.8 msec.

Devices designed to carry 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.
