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.
