# Characteristic Impedance of a Stripline Calculator Online

The Characteristic Impedance of a Stripline Calculator is a tool that computes the characteristic impedance of a stripline based on specific parameters related to the substrate material and trace dimensions. Understanding the characteristic impedance is crucial in designing high-frequency circuits and transmission lines.

### Formula of Characteristic Impedance of a Stripline Calculator

The formula used for calculating the characteristic impedance (Z₀) of a stripline is:

Z₀ = (87 / sqrt(εr + 1.41)) * ln(5.98 * h / w + 1.41)

Where:

• Z₀ is the characteristic impedance in ohms.
• εr represents the relative permittivity (dielectric constant) of the substrate material.
• h denotes the height of the substrate in inches or meters.
• w signifies the width of the trace in inches or meters.

### Table of General Terms

This table helps users understand the terms associated with the calculator, simplifying their understanding and usage.

### Example of Characteristic Impedance of a Stripline Calculator

Consider a scenario where you have a substrate with a relative permittivity (εr) of 4, a substrate height (h) of 0.1 inches, and a trace width (w) of 0.02 inches. Plugging these values into the formula, the Characteristic Impedance of the Stripline Calculator computes the characteristic impedance, providing a result that aids in the design and optimization of electronic circuits and transmission lines.
