Surface Mount Fuses  
Ceramic Fuse > 441 Series  
441 Series – 0603 High I2t Fuse  
RoHS Pb  
Description  
This 100% Lead-free, RoHS compliant and Halogen-free  
fuse series has been designed specifically to provide over  
current protection to circuits that see 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.

Notes:  
Devices designed to carry out 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 < 0.8 msecs.  
2. Nominal Resistance measured with < 10% rated current.  
3. Nominal Melting I²t measured at 1 msec. opening time.  
Devices designed to be mounted with marking code facing up.  
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
