![]() Air-core inductors wound on plastic bobbins are an economical solution, while inductors with iron or ferrite cores have higher values of inductance as their cores are magnetic. The ability to oppose current change is referred to as “inductance.” At Prem Magnetics, you can find coils with inductance values of 0.9µH at 13.0ADC, to 22mH at 2.4ADC. As the current changes, an electromotive force is created and the inductor opposes the change. As the alternating current passes through, it is stored by the inductor in a magnetic field. Inductors have two terminals, and are designed to have electricity flow through them. They are crucial to electromagnetic induction. ![]() Inductors are small but essential parts in countless products used every day by individuals and organizations across an extensive number of industries. Formed from wound, insulated wire, inductors are also often referred to as “coils.” Inductors are known by multiple names, and may be referred to as “reactors”, or “chokes”.
