Selecting Surface-mount Fuses

Fuse selection seems straightforward, in that, you pick one which has a current rating just a bit higher than your worstcase system
operating current. Unfortunately, it’s not that simple. There are derating considerations for operating current and application
temperature. Turn-on and other system operations (like processor speed changes or motor start up) cause current surges or
spikes that also require consideration when selecting a fuse. So selecting the right fuse for your application is not as simple as
knowing the nominal current drawn by the system.

However, the basic considerations for fuse selection are shown in the flowchart presented in Figure 6. Following this flow chart
will help you select a fuse best suited for your application conditions

Temperature Derating Of The Time Delay Ceramic Tube Surface Mount Brick Fuse 1A DC 350V 400V

A fuse is a temperature sensitive device. Therefore, operating temperature will have an effect on fuse performance and lifetime.
Operating temperature should be taken into consideration when selecting the fuse current rating. The Thermal Derating Curve for
surface mount fuses is presented in Figure 4. Use it to determine the derating percentage based on operating temperature and
apply it to the derated system current.
