Because inductance opposes change in AC current, the measured current seen in a circuit “lags” the voltage by some measurable amount of time. In these instances, they are most likely to be referred to as reactors. Inductors can be found in electrical transmission systems.
You also have the option to request custom inductors which we can design and manufacture to your exact specifications. At Prem Magnetics, you’ll find economical, bobbin core inductors, PC mount inductors, surface mount inductors, through-hole mount inductors and switchmode power supply inductors. There are many varieties of inductors available to meet a wide range of needs. Inductors have countless applications in electronic equipment where energy needs to be stored. The higher the inductance, the greater the expected voltage. Inductance is also impacted by how tightly the wire is wound and whether the inductor has a magnetic (iron or ferrite) core.Īs the current and the magnetic flux changes, voltage is produced. Prem Magnetics offers a wide range of coils to fit your budget.Ĭoiled wire increases magnetic flux, therefore, the more coils, the higher inductance you might expect from your inductor. 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”.
