Surface Mount Fuses  
Ceramic Fuse > 438GT Series  
RoHS Pb  
438GT Series – 0603 Fast-Acting Fuse  
Description  
The 438GT 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 150ºC.  
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  
• Suitable for both leaded  
and lead-free reflow/  
wave soldering  
Agency Approvals  
• 100% Lead-free,  
RoHS compliant and  
Halogen-free

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