AirMatrix® Surface Mount Fuses
Environmental Tests:
Fuse Selection and Temperature De-rating Guideline:
The ambient temperature affects the current carrying
capacity of fuses. When a fuse is operating at a
temperature higher than 25oC, the fuse shall be “de-
rated”.
To select a fuse from the catalog, the following rule
may be followed:
Catalog Fuse Current Rating = Nominal Operating
Current / 0.75 / % De-rating at the maximum operating
temperature.
Example: At maximum operating temperature of 65oC,
% De-rating is 90%. The nominal operating current is 4
A. The current rating for fuse selected from the catalog
shall be:
4 / 0.75 / 90% = 5.9 or 6.3 A.
