Introduction of Fixed Inductors

Fixed inductors, also known as coils or choke coils, are passive electronic components used in a variety of electronic circuits. They are composed of a coil-shaped wire wound around an iron core or a ceramic core, usually with a large number of windings to increase inductance. The fixed inductors have the role of delaying or blocking electric current, and also storing energy in the form of magnetic field. They can be used in a variety of electronic circuits, including power supplies, voltage regulators, oscillators, RF amplifiers and electronic filters. Generally speaking, the fixed inductors can be divided into three categories: air core inductors, ferrite core inductors and toroidal core inductors. Air-core inductors use no core material due to their low-frequency applications, but they have limited inductance capabilities. Ferrite core inductors are made from a ferrite material and are used in a wide range of circuits, such as radio receivers, power supplies and amplifiers. Toroidal inductors use a donut-shaped core that allows the wire to wrap around both sides, which results in the inductance of the coil being more concentrated and less prone to interference from the outside environment. Fixed inductors should be selected carefully according to their inductance, DC resistance, frequency response, maximum current and temperature coefficient.

IHM2PM151K Application and Working Principle

The IHM2PM151K is a fixed inductor manufactured by Murata. It is a ferrite core inductor with two pin terminals. The inductor has an inductance of 150 µH, and can support a maximum current of 1 A. The operating temperature range of the device is -20 to +85°C. The device has a coil construction consisting of a magnetically insulated iron-core, which allows it to provide high-frequency characteristics. The IHM2PM151K is mainly used in power supplies, fuel injectors, automotive circuits, TVs and other consumer electronic products. It can also be used in RF circuits to reduce noise and distortion. The device allows current to flow in the opposite direction, preventing it from becoming an inductor when the current flows in the same direction. This feature allows it to be used in circuits that require quick switching of inductors. The working principle of the IHM2PM151K is based on the Faraday’s law of induction. The law states that when a current carrying conductor cuts through a magnetic field, a voltage is induced in the conductor. Similarly, when the applied DC voltage is changed, the current flow through the inductor also changes, and this produces a changing magnetic field around the inductor, which will induce a voltage in the opposite direction. By utilizing this principle, the IHM2PM151K can provide efficient current control in circuits.

Conclusion

In conclusion, the IHM2PM151K is a fixed inductor widely used in power supplies, automotive circuits, fuel injectors and TVs. It is a ferrite core inductor featuring two terminals and an inductance of 150 µH. The device is designed to allow current to flow in both directions, and is mainly used in circuits that require rapid switching of inductors. The device operates based on Faraday’s law of induction, and is capable of controlling current efficiently in circuits.
