Surface Mount Fuses

Ceramic Fuse > 441 Series

441 Series – 0603 High I

t Fuse

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.

Notes:

1. DC Interrupting Rating tested at rated voltage with time constant < 0.8 msecs.

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

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

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

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.
