Design reliable PCBs by ensuring your traces can handle the heat. This calculator uses the IPC-2221 standard to determine the minimum width required to prevent your copper traces from overheating.
PCB Trace Width
Calculate trace width based on IPC-2221
Required Width:

0.00 mm
Calculations are based on ambient temperature. For boards inside tight enclosures with poor airflow, it is recommended to add a 10-20% safety margin to the width.
