Surface Mount Fuses Datasheet

438 Series

0603 Fast-Acting Fuse

RoHS Pb

Description

The 438 Series is a 100% Lead-free, RoHS compliant and

Halogen-free fuse series designed specifically to provide over-

current protection to circuits that operate under high working

ambient temperature up to 150ºC.

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:

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.

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 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.

Speciﬁcations are subject to change without notice.
