Calculation of current-carrying capacity
Reliable management of high currents..
Construction spaces keep getting smaller while currents keep getting larger. It is our mission to continue increasing the capacity of the assembly. With our customised and software-based calculation tool, we can provide you with targeted support that allows you to optimise the current carrying capacity of your PCB. Together, we will find the right technology for your application while avoiding critical limits. It’s important to ensure that the flow of current from A to B is managed in an optimal way.
We take the following aspects into consideration in our calculations:
- Temperature conditions
- PCB technology
- Layer structure
- Number and layout of high-current tracks
The result: a stable and reliable performer.
Layer structure as influencing factor
The dimensioning of the conductors is subject to a standard set of rules. Therefore, use our practical high-current calculator for your initial calculations. This tool offers you a simple and quick way to calculate the necessary conductor width for high-current conductors on an FR4 PCB. Please enter the following values: :
*Calculation provides a guide value based on a test layout 160 mm x 100 mm; Thickness 1,6 mm; Base material circuit board FR4 (λ = 0,25 W/mK); No convection (λ = 0,025 W/mK); Room temperature 20 ⁰C.
