Inductors in Radio Equipment

The name “inductor” is just another term from an electrical coil. An inductor has two terminals and it passively resists changes in the electric current. The inductor stores energy in the magnetic field while the current is being applied. Voltage is induced only when the current passing through the inductor changes. Most inductors are built with a magnetic core that helps to increase the magnetic field and enamel coated wire is wrapped around the core to increase the magnetism. Inductors of varying sizes are used in a wide variety of common electrical applications, including radios. Inductors in radio equipment allow for an alternating current that is free from interference.

The inductors that are used in radio equipment are extremely small; sometimes they are only a few millimeters across and consist of a few small turns of wire. Because a radio is essentially an AC (alternating current) application, an inductor is necessary to make sure that the device reacts properly to AC signals of different frequencies. Without this small component, the radio would not be able to handle all of the variations in the incoming frequencies and it would be totally useless. As mobile electronic devices that use radio frequencies have become smaller and smaller, engineers have had to find ways to develop even smaller inductors. Some inductors are now just a fraction of a millimeter in length, making them small enough to be integrated into a circuit board without taking up the limited space in a mobile device.

At Sag Harbor Industries, we specialize in manufacturing inductors for a wide variety of products and applications. If the inductor you need doesn’t already exist in our line of products, we can work with you to create a custom inductor. Our design and engineering team is capable of creating a perfect customized solution for your needs. Once we’ve come up with a working prototype, we will put an optimized manufacturing process in place to make your custom inductors as efficiently as possible. We do all of this because we want to put our customers first by being flexible enough to meet their needs. That’s the Sag Harbor advantage.
