Microstrip Trace Resistance Calculator
The Microstrip Trace Resistance Calculator is a tool used in electrical engineering to determine the resistance of a microstrip transmission line. It calculates the resistance of a copper PCB trace, given the trace length, width, thickness, and ambient temperature.
Formula
The following formula determines the Microstrip Trace Resistance for a given PCB trace.
Where:
R= trace resistance
ρ= resistivity
L= length
T= trace height
W= trace width
Note:
ρ copper = 1.7 x 10-6 ohm-cm
α copper (temperature coefficient) = 3.9 x 10-3 ohm/ohm/C
What is a Microstrip Trace?
A trace is a conductive path that carries electrical signals on a circuit. Traces are mostly made of copper, but can also be made of aluminum or gold. It has a defined width, height, and thickness. A microstrip is a metallic trace, separated from the ground plane using a substrate, which transmits electrical signals between components. Microstrips are very light and low-power-consuming components used in microwave technology such as antennas, couplers, etc.
