Fixed Inductors

An inductor, or simply an inductance, is a device which is used to store electrical energy in the form of an electromagnetic field when electric current passes through it. It is characterized by its ability to resist changes in electric current. A fixed inductor is an inductor whose inductance is fixed and permanent and cannot be adjusted.

LQH32DN4R7M23L application field and working principle

The LQH32DN4R7M23L fixed inductor is used in various applications that require current stabilization and low-noise operation such as switching power supplies, converters, DC-DC modules, and motor control circuits. This inductor is made up of four magnetic cores, and each core is made of enamelled copper wire that is wound on a copper former, known as an eyelet. When electric current passes through these cores, an electromagnetic field is created in the space between them. These fields interact with each other in such a way that a magnetic flux will be created in the core, aiding in the storage of electrical energy.

The LQH32DN4R7M23L fixed inductor can also be used as an RF filter to reduce EMI and RFI disturbances. This can be achieved by using its magnetic flux to absorb and dissipate the high-frequency electromagnetic waves generated by the electronic equipment. It is also an ideal device for eliminating EMF and RF radiation from transmitting devices such as cell towers and radio base stations.

The principle behind the working of the LQH32DN4R7M23L fixed inductor is based on the relationship between inductance and current. As current passes through the inductor, a magnetic field is created that is proportional to the amount of current flowing through it. This magnetic field interacts with the core of the inductor and induces an opposing electromotive force (EMF) that is proportional to the rate of change of current. This opposing EMF will resist the applied current and thus limit it to a certain level.

The LQH32DN4R7M23L fixed inductor also provides a more efficient and reliable way of controlling electrical current as compared to conventional filtering techniques. Its consistent inductance helps reduce the amount of power consumed during current flow and provides a more stable current output. In addition, its ability to filter out EMI and RFI signals makes it an ideal choice for applications in industrial environments.

Fixed inductors, such as the LQH32DN4R7M23L are widely used in various types of power supplies, converters, DC-DC modules, and motor control circuits. Its ability to store electrical energy, filter out electrical noise, and limit current makes it an essential component for many applications.
