Surface Mount Fuses  
Ceramic Fuse > 440A Series  
440A Series, 1206 High I2t Fuse  
RoHS Pb  
Description  
The 440A Series AECQ-Compliant 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  
• OperatingTemperature  
from -55ºC to +150ºC  
• 100% Lead-free, RoHS  
• Ultra high I2t values  
• Fast response to faulty  
current to ensure over-

Notes:  
1. AC Interrupting Rating tested at rated voltage with unity power factor. DC Interrupting  
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.  
Rating tested at rated voltage with time constant < 0.8 msec.  
2. Nominal Resistance measured with < 10% rated current.  
3. Nominal Melting I²t measured at 1msec. opening time.  
Devices designed to be mounted with marking code facing up.  
4. Nominal Voltage Drop measured at rated current after temperature has stabilized.
