Fixed Inductors

A fixed inductor, also known as an inductor, is an electrical component that stores energy in its electric field. It is a component that stores energy in a magnetic field when it is exposed to an electric current. The name "fixed inductor" refers to its form, consisting of a permanent inductive coil with fixed inductance. The term "inductor" is used to refer to any device that stores electrical energy in this type of electric field.

The LQH32DN2R2M23L is a typical fixed inductor. This inductor is a metal oxide semiconductor (MOS) inductor that acts as an electronic component and is widely used in telecommunications, digital goods, industrial electronics, computing, and other applications. It has a shielded body design, which offers a high degree of protection from external interference, and a high operating frequency range up to 2.2GHz.

In terms of application fields, the LQH32DN2R2M23L fixed inductor is usually used in mobile phones, personal communication systems (PCS) and wireless handsets, as it provides low returns loss and high return loss due to its extremely low DC resistance. The inductor is also suitable for electromagnetic compatibility (EMC) applications. It can also be used in power supplies, AC adapters, as well as automotive, consumer, and medical electronics applications.

Working Principle

The main role of the LQH32DN2R2M23L fixed inductor is to store energy in the magnetic field created by an electric current passing through the winding around a core of ferromagnetic material. The winding is composed of insulated copper wire. This type of inductor works based on the principle of Faraday\'s Law, which states that when a current-carrying conductor moves or is placed in a magnetic field, a voltage difference is induced across its end. The induced voltage is directly proportional to the rate of change in the magnetic field. When an alternating current passes through a coil, an alternating magnetic field is generated that stores energy in the form of a rotating magnetic field, and the voltage on the coil is equal to the changing magnetic field.

To reduce property losses due to eddy currents, an iron core is most often used in LQH32DN2R2M23L inductors. The inductance of the winding is greatly increased by the presence of the core material due to the magnetic flux created when an electric current passes through the winding. An inductance value is specified by the voltage that must be applied to the inductor to create an in-phase current in the winding equal to the current defined for a given inductor type.

In addition, a fixed inductor may also have a core material with ferromagnetic properties to reduce the core losses. The eddy currents that flow through the core material are reduced due to the core\'s magnetic properties. This decreases the amount of heat generated in the core and reduces power consumption. The resistance to AC current can be further decreased by decreasing the number of turns in the winding, while keeping the inductance value constant. This reduces the overall inductance and increases the bandwidth of the inductor.

The LQH32DN2R2M23L fixed inductor also offers high saturation current ratings and low temperature coefficient ratings. This ensures that the inductor can withstand heavy current loads and higher temperature fluctuations, making it a reliable and robust component for high-power applications.

All in all, the LQH32DN2R2M23L fixed inductor is a popular choice in a wide range of applications. Its design offers excellent performance in terms of electromagnetic compatibility, high operating frequency, and high current capacity, while ensuring that its property losses are minimized. As such, the LQH32DN2R2M23L is a great choice for creating efficient and reliable electrical and electronic circuits that will last.
