Fixed Inductors: LQM21PN1R5MCHD Application Field and Working Principle

Fixed inductors are electrical components that can store energy when an electric current is passed through them. The LQM21PN1R5MCHD is a type of fixed inductor that is used in a range of industrial and consumer electronics applications. This article will discuss the application field and working principle of the LQM21PN1R5MCHD.

Application Field

The LQM21PN1R5MCHD is a multi-layer fixed inductor that is specifically designed for use in switching power supplies, switch regulators and DC/DC converters. The inductor features a low equivalent series resistance (ESR) that makes it suitable for higher frequency applications.

The LQM21PN1R5MCHD offers a low stray inductance, which makes it suitable for high speed switching applications. Its low profile and high wattage dissipation make it suitable for high density applications. It is also RoHS-compliant and halogen-free, making it suitable for applications where environmental compliance is required.

Working Principle

Like all fixed inductors, the LQM21PN1R5MCHD works by storing energy when a current is passed through it. When a current is applied to the inductor, it creates a magnetic field that stores the energy as a magnetic field. As the current continues to flow, the energy stored in the magnetic field is increased.

When the current is stopped, the magnetic field collapses and releases the energy stored in the field. This process is known as inductive reactance, and it is what allows fixed inductors to store energy.

The LQM21PN1R5MCHD is designed to offer excellent inductance stability over a wide temperature range, making it suitable for use in severe operating environments such as automotive applications. It is also designed to offer excellent resistance to dv/dt noise, making it suitable for use in high speed switching applications.

Conclusion

The LQM21PN1R5MCHD is a multi-layer fixed inductor that is designed for use in switching power supplies, switch regulators and DC/DC converters. It offers high wattage dissipation and a low profile, making it suitable for high density applications. It also offers a wide temperature range and excellent resistance to dv/dt noise, making it suitable for use in high speed switching applications.

The working principle of the LQM21PN1R5MCHD is based on inductive reactance, which means that it stores energy when a current is passed through it. When the current is stopped, the energy is released, allowing the inductor to perform its function.
