Description
The 441A series AEC-Qualified fuses are specifically tested to
cater to secondary circuit protection needs of compact auto-
electronics application.
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:
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 Re-rating Curve”for additional re-rating
information.
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.
Devices designed to be mounted with marking code facing up.
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
