Surface Mount Fuses

Ceramic Fuse > 501 Series

RoHS Pb

501 Series – High Current 1206 Fast-Acting Fuse

Description

The 501 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 150°C.

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

• 100% Lead-free, RoHS

compliant and Halogen-

free

• Designed to provide

over-current protection

in high current voltage

regulator module (VRM)

applications

Agency Approvals

• Suitable for both leaded

and lead-free reﬂow /

wave soldering

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. DC Interrupting Rating tested at rated voltage with time constant < 0.5 msec.

2. Nominal Resistance measured with < 10% rated current.

3. Nominal Melting I²t measured at 1 msec. opening time. For other I²t data refer to chart.

Devices designed to be mounted with marking code facing up.

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

with fuse mounted on board with 3-oz Cu trace.
