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.
Benefits
• High inrush current withstanding capability
• Ceramic Monolithic structure
• Silver fusing element and silver termination with nickel and tin plating
• Excellent temperature stability
• Strong arc suppression characteristics
