Surface Mount Fuses Datasheet

438GT Series

0603 Fast-Acting Fuse

RoHS Pb

Description

The 438GT 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.

Features

■ OperatingTemperature from

-55ºC to +150ºC

■ Suitable for both leaded

and lead-free reﬂow/ wave

soldering

■ 100% Lead-free,

RoHS compliant and Halogen- ■ Recognized to UL/CSA/NMX

free

248-1 and UL/CSA/NMX 248-

Additional Information

Applications

■ Handheld Electronics

■ Hard Disk Drives

■ SD Memory Cards

■ LCD Displays

■ Battery Packs

Notes:

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.

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

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.

Devices designed to be mounted with marking code facing up.

Speciﬁcations are subject to change without notice.
