Fixed Inductors: 2215-H Application Field and Working Principle

Fixed inductors are electromagnetic components found in electronic circuits, primarily used to store energy in the form of an electric field or a magnetic field, the latter being the most common. The 2215-H is a type of fixed inductor produced by many companies, with distinct engineering properties suitable for certain applications.

Overview of the 2215-H

The 2215-H is a high-precision, general-purpose inductor, designed and available in custom configurations. It is available with custom values for inductance ranging from 1 microhenry to 1.2 millihenry. It is a two-terminal inductor that can operate in a wide range of frequencies and is designed to handle continuous and peak currents without an increase in temperature in order to provide consistent performance. The 2215-H also features a high efficiency core which allows it to maintain a strong magnetic field even under high currents.

Application of the 2215-H

The 2215-H provides performance benefits in a wide range of applications, from providing dedicated inductive storage for high voltage and power electronics to being the main energy storage component in various RF circuits. In high voltage applications, the 2215-H provides high energy storage and relatively low resistance in small sizes. Additionally, the 2215-H can be used in various RF circuits, including antenna circuit designs, filters or combiners. The 2215-H\'s high efficiency core also makes it well suited for DC/DC converters, isolating the primary circuit from secondary circuits. In power supplies, the 2215-H delivers a reliable contactless current transfer, while also minimizing losses to the core.

Working Principle of the 2215-H

The 2215-H inductor works on the principle of Faraday’s law of induction. According to this law, when an alternating current passes through a conductor, a magnetic field is generated which induces a current in the secondary winding. The induced current in this secondary winding is equal to the number of turns in the winding multiplied by the magnitude of the magnetic field created. Furthermore, if the magnetic field moves through the conductor, an additional induced current will be created in the coil in the same direction.

In practice, a 2215-H inductor is made up of one or more turns of wire which are insulated from one another and connected in parallel. The current will flow through the wire which in turn creates a magnetic field. When the primary winding is exposed to an alternating current, a secondary winding is induced with an electric current which equals the number of turns in the winding and the magnitude of the magnetic field. This is known as mutual induction.

Conclusion

The 2215-H is an ideal fixed inductor choice for various types of applications ranging from energy storage, RF circuits, high voltage applications, and power supplies. This fixed inductor is resistant to temperature fluctuations which make it a reliable and consistent component. Additionally, the 2215-H works on the principle of Faraday’s law of induction and features one or more turns of wire surrounded by an insulation material, connected in parallel.
