Understanding Power Inductor Parameters | Article | MPS
An inductor is a component in an electrical circuit that stores energy in its magnetic field. Inductors convert electrical energy into magnetic energy by storing, then supplying energy to the circuit to regulate current flow. This means that if the current increases, the magnetic field increases. Figure 1 shows an inductor model.
Time Constant in DC Circuit Inductors
An inductor is, therefore, characterized by its time constant (τ = tau), which is determined using the formula: τ = L R τ = L R. where. τ = time constant in seconds. L = inductance in henrys. R = resistance in ohms. This expression shows that a greater inductance and a lower resistance will cause a longer time constant.
