Surface Mount Fuses Datasheet  
440A Series  
AEC-Q200 Qualified > Ceramic Fuse  
RoHS Pb  
Description  
The 440A Series AEC-Qualified 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. This high I2t fuse series is designed to  
have ultra high inrush current withstand capability to avoid  
nuisance fuse open.  
Features & Benefits  
■ OperatingTemperature from  
■ Fast response to faulty  
current to ensure over-current  
protection to sensitive  
-55ºC to +150ºC  
■ 100% Lead-free, RoHS  
compliant and Halogen-free  
electronic component  
■ Recognized to UL/CSA/NMX  
248-1 and UL/CSA/NMX 248-14  
■ AEC-Q200 Qualified  
■ Ultra high I2t values

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