AV-E06
PCB Trace Width
IPC-2221 trace width for a current and temperature rise, plus trace resistance, voltage drop and power loss.
● Runs on your device; nothing is uploadedHow to use it
- Choose External layer or Internal layer.
- Enter the Current (A) and allowed Temperature rise (°C).
- Pick the Copper weight and set the Ambient temperature.
- Add a Trace length (mm) to see resistance, voltage drop and power loss.
Limits
- Copper weight options
- 0.5–4 oz/ft²
- IPC-2221 fit, current
- up to 35 A (warns above)
- IPC-2221 fit, temperature rise
- 10–100 °C (warns outside)
- IPC-2221 fit, width
- up to 400 mil / 10.2 mm (warns above)
- IPC-2221 fit, copper
- 0.5–3 oz (warns outside)
Features
- IPC-2221 formula with k = 0.048 external and 0.024 internal
- Width in mil and mm, plus cross-section and copper thickness
- Resistance with copper resistivity corrected to ambient plus rise
- Warnings when inputs fall outside the fitted IPC-2221 curves
