NOTES:  Test Conditions 

All test for ratings 300mA - 5A were conducted with fuse samples soldered on a PCB (1.6mm thick) test board with copper traces measuring 0.035 mm (35μm) nominal thickness (1 oz.clad), 5mm wide and 100 mm overall length. 

All test for ratings 6A-8A were conducted with fuse samples soldered on a PCB (1.6mm thick) test board with copper traces measuring 0.070 mm (70μm) nominal thickness (2 oz. clad), 7.5mm wide and 100 mm overall length. 

Device designed to be mounted with marking facing up. Device designed to carry rated current for 4 hours minimum. It is recommended that device be operated continuously at no more than 80% of rated current when in a +25°C ambient, with further derating at elevated ambient temperatures.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Request a quote →

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
