NOTES: Test Conditions
All test for ratings 500mA
-
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

ucted with fuse samples soldered on a PCB (1.6mm thick) test board with copper traces measuring 0.070
mm (70
μ
m) 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.
