Fuse Datasheet  
Surface Mount Fuses  
Ceramic Fuse > 806 Series  
RoHS Pb  
Description  
The 806 Series fuse is designed specifically to provide overcurrent  
protection to circuits that operate under high working ambient  
temperature up to 150 °C.  
Its 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 & Benefits  
Recognized to UL/CSA/NMX  
248-1 and UL/CSA/NMX  
248-14  
High current ratings in  
small size  
High performance  
materials provide improved  
performance in elevated  
ambient temperature  
application  
OperatingTemperature from  
-55 ºC to +150 ºC  
Designed to provide over-  
current protection in high  
current Voltage Regulator  
Module (VRM) applications  
Additional Information  
Avoids nuisance opening  
due to high inrush and surge  
current inherent in the  
system  
100% Lead-free, RoHS  
compliant, and Halogen-free  
Suitable for both leaded  
and lead-free reflow/wave  
soldering

Notes:  
1. DC Interrupting Rating tested at rated voltage with time constant < 0.1 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.  
4. Nominal Voltage Drop measured at rated current after temperature has stabilized and with fuse mounted on board with 3 oz Cu trace.  
Devices are designed to carry rated current for 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 are designed to be mounted with marking code facing up.
