High Current Calculator
This tool offers a quick and easy way to calculate the required track width for high-current conductor tracks on an FR4 PCB. Please enter the following values:
We'd be happy to create a custom solution concept for your high-current application.
The calculation returns a guide value on the basis of a 160 x 100 mm test layout. Thickness 1.6 mm. Base material of PCB FR411 = 0.25 W/mK. No convection 11 = 0.025 W/mK. Room temperature 20⁰C.
