Surface Mount Fuses Datasheet

438A Series

AEC-Q200 Qualiﬁed > Ceramic Fuse

RoHS Pb

Description

The 438A series AEC-Q200 Qualified fuses are specifically tested

to cater secondary circuit protection needs of compact auto

electronics application.

The general design ensures excellent temperature stability and

performance reliability.

The high I²t values which is typical in the Littelfuse ceramic fuse

family ensure high inrush current withstand capability.

Notes:

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

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.

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 Re-rating Curve”for additional re-rating

information.

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

Devices designed to be mounted with marking code facing up.

Speciﬁcations are subject to change without notice.
