For the patch inductors, it is known that its application is relatively wide, the English name is Chip inductors, also known as power inductors, high current inductors and surface mounted high power inductors.
The patch inductor is a nonlinear electronic component, which requires that the current through the inductor cannot change, so it will carry out a high resistance state for the current that changes.
The standard method of the color ring inductance is the same as the color ring resistance, and the volume size can distinguish the size of the current that can pass through.
First, we need to understand that inductance is a property of a closed loop, that is, when the current through the closed-loop changes, the electromotive force will appear to resist the current change.
Inductor is a commonly used component in switching power supply, because its current, voltage phase is different, so theoretically the loss is zero.
Inductor is a passive component, and only works when current passes through it. Its function is to convert ac to dc, and then filter out part of the noise wave, so that the smooth wave can pass through.
