Prem Magnetics is proud to design and manufacture a wide range of wire-wound inductors. Browse this category to find the inductors, choke, reactors and coils for electromagnetic induction that best meets your needs.
Inductors are known by multiple names, and may be referred to as “reactors”, or “chokes”. Formed from wound, insulated wire, inductors are also often referred to as “coils.”
Inductors are small but essential parts in countless products used every day by individuals and organizations across an extensive number of industries. They are crucial to electromagnetic induction. Inductors have two terminals, and are designed to have electricity flow through them. As the alternating current passes through, it is stored by the inductor in a magnetic field. As the current changes, an electromotive force is created and the inductor opposes the change. 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. 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. Prem Magnetics offers a wide range of coils to fit your budget.
Coiled wire increases magnetic flux, therefore, the more coils, the higher inductance you might expect from your inductor. Inductance is also impacted by how tightly the wire is wound and whether the inductor has a magnetic (iron or ferrite) core.
As the current and the magnetic flux changes, voltage is produced. The higher the inductance, the greater the expected voltage.
Inductors have countless applications in electronic equipment where energy needs to be stored. They are commonly found in:
There are many varieties of inductors available to meet a wide range of needs. 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. You also have the option to request custom inductors which we can design and manufacture to your exact specifications.
Inductors can be found in electrical transmission systems. In these instances, they are most likely to be referred to as reactors. Because inductance opposes change in AC current, the measured current seen in a circuit “lags” the voltage by some measurable amount of time. This effect can be used in a speed control system to alter the starting current.
A choke is a type of inductor often found in radio equipment, with the ability to enable DC to pass, while blocking AC current over a specific frequency band. Prem Magnetics manufactures Attenuating EMI Wideband Bead Chokes and custom chokes to meet a wide range of customer needs.
