Ceramic Fuse > 438 Series

438 Series – 0603 Fast-Acting Fuse

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

Rerating Curve”for additional rerating 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 1 msec. opening time.

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