Today, 07:15KlausST replied to a thread PCB Trace width calculator: Average current vs RMS current in Power ElectronicsHi , The basic problem is: The current will cause heat, too much heat will melt the trace. Now Imagine: There is purely AC current. Do you...2 replies | 69 view(s) -
Today, 07:05Hi, Yes. With low current. But don't expect good accurracy nor stability...they are not designed for it. Klaus1 replies | 75 view(s)
