Fixed inductors are electrical components used mainly to provide a constant inductance to a circuit. The LQH55DN222M03L is an example of a fixed inductor, and in this article we will be looking at its application field as well as its working principle.

Application Field

The LQH55DN222M03L is a high performance, surface mount fixed inductor. It is typically used in a wide range of applications within the consumer electronics, connectors, medical, automotive, and telecommunications industries. It is a voltage-controlled device, offering both low inductance and low DC resistance in a miniature and low profile package. Additionally, it is also designed to be highly efficient in terms of power dissipation, making it an ideal choice for applications where heat, space, and power are of paramount importance.

Working Principle

An inductor, in general, works by opposing the change of current in an electric circuit. A fixed inductor such as the LQH55DN222M03L is no different; it is designed to provide a constant amount of inductance to a circuit, and thus, opposes any current changes. The amount of inductance this device exhibits is determined by the number of turns of the wire winding and the overall size of the coil, both of which are designed to be consistent and not easily changed. This is why it is classified as a ‘fixed’ inductor.

The LQH55DN222M03L is an electrolytic type of inductor, which is designed to utilize the combined effects of electrical and mechanical forces. These forces, when applied to the winding of the coil, cause an electrokinetic effect, which in turn leads to the production of a magnetic field. This magnetic field opposes any changes in the circuit’s current, ensuring that the inductance of the device remains constant.

Conclusion

The LQH55DN222M03L is a high performance, surface mount fixed inductor. It is designed to provide a constant amount of inductance to a circuit despite changes in current, and is suitable for use in a variety of applications within the consumer electronics, connectors, medical, automotive, and telecommunications industries. Additionally, its efficiency makes it an ideal choice for applications where heat, space, and power are of paramount importance.
