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 (70m) 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 +25C ambient, with further derating at elevated ambient temperatures.
