Ceramic Fuse > 440 Series

440 Series, 1206 High I²t Fuse

Description

The 440 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 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.

Notes:

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

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

Derating Curve”for additional derating information.

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

2. Nominal Resistance measured with < 10% rated current.

3. Nominal Melting I²t measured at 1 msec. opening time.

Devices designed to be mounted with marking code facing up.

4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
