Fuse Datasheet  
440 Series  
1206 High I2t Fuse  
RoHS Pb  
Description  
The 440 Series is a 100% RoHS Compliant, lead-free and halogen-  
free fuse series designed specifically to provide over-current  
protection to circuits that operate under high working ambient  
temperatures up to 150ºC and high inrush currents. The general  
design ensures excellent temperature stability and performance  
reliability. This high I2t fuse series is designed to have ultra high  
inrush current withstand capability to avoid nuisance fuse open.  
Features and Benefits

Ultra high I2t values  
-55ºC to +150ºC  
Recognized to UL/CSA/NMX  
RoHS compliant, lead-free and  
248-1 and UL/CSA/NMX 248-14  
halogen-free  
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 Derating Curve”for additional derating  
information.  
1. Nominal Resistance measured with < 10% rated current.  
2. Contact Littelfuse if application transient surges are less than 1 ms.  
3. Nominal Voltage Drop measured at rated current after temperature has stabilized.  
Devices designed to be mounted with marking code facing up.
