Strip line Trace Width Calculation, Formula, Example

Strip line Trace Width Calculator

The maximum current that a stripline can safely handle is a function of its width. For this reason, trace width is important in the design of striplines. This calculator computes the trace width of a stripline if the maximum current, trace thickness, temperature rise, ambient temperature and length are given. This tool will also compute the resistance of the stripline, the voltage drop on it, and the resulting power dissipation.

Formula

Where:

$$\Delta T$$ = temperature rise

$$W$$ = trace width

$$T$$ = trace thickness

$$L$$ = trace length

$${\rho }_{cu}$$ = resistivity of Copper = 1.7 x 10^-6

$${\alpha }_{cu}$$ = temperature coefficient of Copper = 3.9 x 10^-3
