437A Series – 1206 Fast-Acting Ceramic Fuse
Description
The 437A Series AECQ-Compliant fuses are specifically
tested to cater to secondary circuit protection needs of
compact auto-electronics applications.
The general design ensures excellent temperature stability
and performance reliability. In addition to this, the high I²t
values typical of the Littelfuse Ceramic Fuse family ensure
high inrush current withstand capability.
Features
• OperatingTemperature
from -55ºC to +150ºC
• Fast response to faulty
current to ensure over-
current protection for
sensitive electronic
components
• 100% Lead-free, Halogen-
Free and RoHS compliant

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.
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 1 msec. opening time.

Application testing is strongly recommended. Specifications are subject to change without notice.
Revised: 11/16/17
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.

Note:
1. Re-rating depicted in this curve is in addition to the standard re-rating of 20% for
continuous operation.
Example:
0.1
For continuous operation at 75 degrees celsius, the fuse should be rerated as follows:
I = (0.80)(0.85)IRAT = (0.68)IRAT
