NOTES: Test Conditions
All test were conducted with the fuses soldered to a PCB with a nominal thickness of 1.6mm
with copper traces measuring 100mm overall length. Copper trace/width as described below.
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.
