# Broadside Trace Inductance

A broadside trace inductance calculator is a tool used to calculate the inductance of a broadside trace on a printed circuit board (PCB). Inductance is a property of an electrical circuit that describes the amount of energy stored in the magnetic field created by the current flowing through the circuit.

A broadside trace on a PCB is a common example of an inductor. When a current flows through the trace, a magnetic field is created around the trace. The strength of the magnetic field depends on the amount of current flowing through the trace and the geometry of the trace.

The inductance of a broadside trace on a PCB depends on several factors, including the width and thickness of the trace, the height of the trace above the ground plane, and the length of the trace. A broadside trace inductance calculator takes these factors into account and provides an estimate of the inductance of the trace.

To use a broadside trace inductance calculator, you typically input the width and thickness of the trace, the height of the trace above the ground plane, and the length of the trace. The calculator then uses a formula to calculate the inductance of the trace based on these parameters.

One commonly used formula for calculating the inductance of a broadside trace on a PCB is:

L = (μ₀ × h) / (π × (w + 1.1 × t) × ln(2h / t))

where L is the inductance in henries, μ₀ is the permeability of free space (4π × 10⁻⁷ H/m), h is the height of the trace above the ground plane, w is the width of the trace, and t is the thickness of the trace.

Using a broadside trace inductance calculator can be helpful in designing PCBs that require inductors. By knowing the inductance of a broadside trace, you can select the appropriate components and ensure that your circuit will operate as intended.
