Series
441 Series – 0603 High I2t 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 150C) and high inrush currents.
The general design ensures excellent temperature stability
and performance reliability.
This high It 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 It 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.
Devices designed to be mounted with marking code facing up.
