NOTES: 

All tests were conducted with the fuses soldered to a printed circuit boards with a nominal thickness of 1.6 mm. The copper test circuit trace was a printed circuit with an overall length of 100 mm, copper thickness/width as described Fuse rating Test Board Trace Dimensions below. The printed circuit boards were mounted by screws to a test fixture having brass blocks for connection of the test leads. All samples were soldered to the test boards by the 250mA-5A 1 oz. copper, 5.0mm wide. manufacturer. 6A-20A 3 oz. copper, 10mm wide.
