Calculates the current a via needs to raise its temperature over ambient per IPC Calculates the current a conductor needs to raise its temperature over ambient per IPC Now also calculates DC resistance with temperature compensation.

This version uses the IPC formula for finding conductor current vs. Version 4 series is accurate to the IPC but may be too conservative in many cases. All online calculators that use the IPC formula are now obsolete!!! We have also been working on developing our own formulas for current to get as close as possible to the measured data charts of the IPC The conservative chart in the IPC is really just the internal chart from the IPC so that was the formula used. If you are not yet familiar with the IPC then please be aware that there are two separate charts for finding conductor current vs. In order to understand the PCB Toolkit version differences, I have added this brief description of the version series.

However, this valuable method is not without its pitfalls. Although being more specific than effective diameter bracketing, inductance calculations based on this formula remain approximative for two reasons.
