Power Inductor Polarity at Sandra Raines blog

Power Inductor Polarity. The polarity depends on the direction of the current flowing through it. The polarization marker just lets you get them all. Power inductors are typically used for energy storage in dc/dc converters or high current noise filter applications, including motor speed. If a current is moving from point a to point b (say), the inductor stores the current in the coil inturn. Mounting the inductors in various directions relative to other parts of your pcb will give (slightly) different results. The inductor immediately switches polarity and gives its stored energy back to the circuit. How flux orientation can reduce radiated emission. While there is no defined electric polarity for inductors, direction of current does matter because of a phenomenon called inductor kickback. When that happens, the input voltage source and the inductor, which is now also acting as a voltage source, are in series and based on kirchhoff’s voltage law, the two sources add, doubling the input voltage at the diode.
