Fixed inductors are components that are designed to provide a fixed value of inductance in a circuit. An inductor that is not adjustable is known as a fixed inductor. The LQH43NN220J03L is a type of fixed inductor designed for many different applications. This article will review the applications and working principles of the LQH43NN220J03L.

Application Field

The LQH43NN220J03L is a high-inductance, low-profile fixed inductor. It is designed for use in high-voltage switching power supplies, motor-control systems, and other DC-DC converter applications. It is also suitable for use in high-frequency, high-current circuits. Its low effective surface area and high inductance make it ideal for high-density circuit boards. It can also be used in switching regulators, DC-AC converters, and other energy-saving power supply systems. Furthermore, it is suitable for use in consumer electronics, communications, automotive, and industrial applications.

Working Principle

The working principle of the LQH43NN220J03L is relatively simple. It consists of a coil of wire wrapped around a core which is made from either iron or air. The core stores the energy in the inductor. When an alternating current passes through the coil, the magnetically stored energy in the core creates an opposing magnetic field. This field produces an electromotive force in the opposite direction to the applied current, thus producing the inductance. This makes the inductor react differently to AC and DC currents.

When a DC current passes through the coil, the core stores the energy and provides resistance, thus reducing the current flow. When an AC current passes through the coil, the core stores the magnetic energy and releases it in the form of an opposing voltage wave. This opposition causes the current to swing above and below its starting current and this is known as inductive reactance. It is this reactance that makes the inductor ideal for applications such as filters, smoothing circuits, and DC-AC conversion.

Conclusion

The LQH43NN220J03L is a high-inductance, low-profile fixed inductor. It is designed for use in high-voltage switching power supplies, motor-control systems, and other DC-DC converter applications. It is also suitable for use in high-frequency, high-current circuits. The working principle of the LQH43NN220J03L is based on the stored energy of the core and the opposing voltage waves that are created. This makes it ideal for applications such as filters, smoothing circuits, and DC-AC conversion. As such, the LQH43NN220J03L is a versatile and practical fixed inductor.
