PCB Impedance Calculator
Calculate PCB microstrip and stripline characteristic impedance from trace geometry and dielectric properties. Get effective dielectric constant, propagation velocity, and delay for signal integrity analysis.
How to Use PCB Impedance Calculator
Select microstrip or stripline mode, enter trace width, thickness, dielectric height, and dielectric constant (εr). Click Calculate to get characteristic impedance, effective εr, propagation velocity, and delay.
Step-by-Step Instructions
- Select microstrip or stripline transmission line type
- Enter trace width, thickness, and dielectric height in mil
- Set the dielectric constant for your PCB material
- Click Calculate Impedance and review the results
