Introduction to Fixed Inductors

An inductor is an electrical component that stores energy within a magnetic field. Inductors are found in all kinds of electronic circuits, from small power supplies to the large drives used in industrial control. Fixed inductors, also known as passive or non-adjustable inductors, are components whose inductance remains constant across a range of applied voltage and frequency. For example, a fixed inductor might have a resistance value of 1 ohm at 1 kHz and a resistance value of 1 ohm at 10 kHz. LQH3NPN3R3NM device is a series of fixed inductors.

LQH3NPN3R3NM0L Application Field and Working Principle

The LQH3NPN3R3NM0L is a series of fixed inductors designed for use in DC/DC converters and power supply applications. The typical applications include voltage regulator modules, battery chargers, LED lighting, solar energy converters, wireless audio systems, brushless DC motors, and more. The device utilizes a metal core-based construction for superior inductance capability and a low DC resistance for efficient operation.

The series of LQH3NPN3R3NM0L fixed inductors feature an optimal design that ensures the most desirable inductance performance levels. The working principle of these inductors is based on the magnetic field created by the flow of electric current. When current passes through the inductor, a magnetic field is created around the wires. This magnetic field creates a back-emf (electromotive force) that opposes the current flow, a phenomenon known as inductance. The magnitude of the inductance is determined by the size of the inductor, its winding, and the permeability of the core material.

The core is constructed with high quality iron which provides a low magnetic field leakage, and the inductance value is printed on the surface of the case. The operating temperature range is from -40 to +125℃. The ideal operating temperature range is from +25 to +85℃.
