PCB Impedance Calculator

Importance of PCB Impedance Design

In high-speed PCB design, controlling impedance is crucial. Proper impedance matching can:

Reduce signal reflection and improve signal integrity
Lower crosstalk and electromagnetic interference (EMI)
Optimize power transmission and improve system efficiency
Ensure correct transmission and reception of high-speed signals

Use this calculator to quickly estimate the characteristic impedance of PCB traces, providing a reference for your high-speed design.

Note: The results provided by this calculator are for reference only. In actual design, consider other factors such as trace length and frequency, and perform simulation verification.
