NOTES:
All tests were conducted with the fuses soldered to a printed circuit boards with a nominal thickness of 1.6 mm. The copper t
est circuit trace
was a printed circuit with
an
overall length of 100 mm, c
opper thickness/width as described
below. The printed
circuit
b
oards 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 manufacturer
.
Caution
Minimum
fusing point:
The 0678H Series fuse are NOT intended to be operated at currents between 100% and
200% of ampere rating. Prolonged operation at currents
i
n this range may result in overheating of the fuse and/or desoldering of the fuse caps
from the PCB pad
.
