company news about The voltage of fuse drops and cold resistance

Generally speaking, the cold resistance of the fuse is basically a fixed value, and the voltage drop (thermal resistance) will change as the temperature rises and falls. Therefore, in the application, the voltage drop at the rated current is important.

The resistance of the fuse with a lower rated current is large. In low -voltage application conditions, the voltage drop will play a decisive role. In some extreme conditions, the test (application) current that cannot be output cannot be output.

The voltage and cold resistance of the fuse can generally be converted to each other.

The voltage reduction of the fuse is tested for the application AC power.

The cold resistance of the fuse can be tested by DC.
