Splet02. apr. 2024 · How to Determine PCB Trace Width. The General current carrying capacity equation can be defined as: Eq - 01 General currents carrying capacity formula. Where I indicates the current in amperes, ∆T the change in temperature above ambient in °C, and A the cross-sectional area in mils. SpletA fuse will typically have two I 2 T ratings, a minimum withstand rating and a maximum let-through rating, and they are usually somewhat different values. The I 2 T rating of a fuse is a related to the energy it lets through to any given load by the resistance of the load. If the load is a linear resistance with a value of R LOAD, then the ...
