Surface Mount Fuse Datasheet
407A Series
AEC-Q200 Qualified > Ceramic Fuse
RoHS Pb
Description
The 407A Series AEC-Qualified fuse is specifically tested to cater
to secondary circuit protection needs of compact auto electronics
applications.
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 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.
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.
2. Nominal Resistance measured with < 10% rated current.
3. Nominal Melting I2t measured at 1msec. opening time.
• Devices designed to be mounted with marking code facing up.
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
