0603 Time-Lag > Ceramic Fuse > 408 Series

RoHS Pb

Description

Littelfuse 408 Series is a 100% lead-free, RoHS compliant, and

halogen-free fuse designed specifically to provide overcurrent

protection to circuits that operate under high working ambient

temperatures up to 150 ºC and high in-rush currents. The general

design ensures excellent temperature stability and performance

reliability. This high I²t time lag fuse is designed to have ultra-high

in-rush current withstand capability to avoid nuisance fuse open.

Features

■ OperatingTemperature from -55 ºC to +150 ºC

■ UL Recognized to UL / CSA / NMX 248-1 and

UL / CSA / NMX 248-14

■ 100% Lead-free, RoHS compliant, and Halogen-free

■ Suitable for both leaded and lead-free reﬂow / wave soldering

■ Ultra-high I²t values

Notes:

1. 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 derating information.

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

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

•

Devices designed to be mounted with marking code facing up.
