Microstrip Impedance Calculator
Calculate microstrip impedance with ease using our comprehensive online calculator.
Utilize our electrical engineering calculator to accurately determine the Characteristic Impedance, Capacitance per unit length, Inductance per unit length, DC resistance per unit length, and propagation speed of a trace. Simply input the trace width, thickness, dielectric thickness, and relative dielectric constant to obtain these essential parameters. Enhance your circuit design and analysis by utilizing this comprehensive calculator, empowering you to make informed decisions and optimize your electrical engineering projects. Simplify your calculations and streamline your design process with our user-friendly electrical engineering calculator.
\text{Microstrip Impedance } Z_o = \left( \frac{87}{\sqrt{(\text{er}+1.41)}} \right) \cdot \ln \left( \frac{5.98 \cdot h}{(0.8 \cdot w)+t} \right)
T_{pd} = 3.333 \cdot \sqrt{(0.475 \cdot \text{er})+0.67} \cdot \text{dimension}
C = \frac{T_{pd}}{Z_o}
L = \frac{T_{pd} \cdot Z_o}{1000}
D_c = \frac{17.2}{w \cdot t \cdot \text{dimension}^2} \cdot 1000
where
- Zo = Single Ended Impedance
- er = Relative dielectric constant
- h = Trace width
- w = Trace height
- t = Trace thickness
- Tpd = Propagation Delay
- C = Capacitance
- L = Inductance
- Dc = Resistance
- If the dimension unit is mm then dimension=1
- If the dimension unit is mils then the dimension is 0.0254
