Fuse Datasheet
501A Series
AEC-Q200 Qualified > High Current 1206 Fast-Acting Fuse
RoHS Pb
Description
The 501A series AEC-Qualified fuses and Halogen free fuse series
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. The high I2t values which are typical in the
Littelfuse Ceramic Fuse family, ensure high inrush current
withstanding capability.

Notes:
Devices designed to carry rated current for four 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 <0.5msec.
2. Nominal Resistance measured with <10% rated current.
3. Nominal Melting I2t measured at 1 msec. opening time. For other I2t data refer to chart.
Devices designed to be mounted with marking code facing up.
4. Nominal Voltage Drop measured at rated current after temperature has stabilized and with fuse mounted on
board with 3oz Cu trace.
