The Trace Width, Current Capacity and Temperature Rise Calculator is an advanced PCB tool that works based on the latest IPC-2152 standard.

It’s a three-in-one calculator. If you know the values of any of the two parameters (conductor width, max temperature, max current capacity) it determines the third. This trace width calculator also computes resistance at ambient and high temperatures, voltage drop, and power loss at maximum current for internal and external traces.
