Surface Mount Fuses

Ceramic Fuse > 438GT Series

RoHS Pb

438GT Series – 0603 Fast-Acting Fuse

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

Agency Approvals

• 100% Lead-free,

RoHS compliant and

Halogen-free

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.

Devices designed to be mounted with marking code facing up.

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

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

Speciﬁcations are subject to change without notice

Speciﬁcations are subject to change without notice. Application testing is strongly recommended.
