PCB trace impedance
Approximate single-ended microstrip or symmetrical stripline impedance.
Number of Inputs and Type
Persian and English numerals are accepted. Calculations run on your device; inputs are not transmitted or stored.
Result
- Approximate impedance
- 53.9939822 Ω
This IPC-2141 approximation is for a single-ended trace, not a differential pair. For stripline, h is the total separation between ground planes. Final fabrication requires a field solver and the manufacturer's stackup; solder mask is not included.
روش Calculation and راهنما
microstrip: Z=87/√(εr+1.41) ln[5.98h/(0.8w+t)]
