Fixed Inductors are passive electrical components that store energy in their magnetic fields. They consist of a ferromagnetic core made out of iron or ferrite, typically wound with copper or aluminium wire. The inductor is designed to create an opposing electromagnetic field that counteracts any change in current that passes through it.

The LQH3NPN1R0MMRE is a surface-mountable fixed inductor specifically designed for use in automotive electronics systems. It has a maximum rated current of 2.6 A and a maximum peak current rating of up to 10 A. It operates at a low DC rated voltage of 10 V and is available in a range of inductances from 1.0 uH up to 4.7 uH.

The LQH3NPN1R0MMRE is ideal for automotive application fields, such as DC-DC converters, voltage regulator modules, power factor correction, power supply filters, and relay coils. The low rated voltage limits it to applications in which the current remains relatively constant, such as for power factor correction modules.

The working principle of the fixed inductor is based on Faraday\'s law of induction, which states that when a current passes through an inductor, a magnetic field opposing the change in current is created. This opposes any increase or decrease in current that passes through the inductor, causing the current to remain relatively constant.

The LQH3NPN1R0MMRE is constructed from an iron-based core, typically with one or more layers that are wound with copper or aluminium wire. This wire behaves as a magnet when the current passes through it, creating a magnetic field. The resistance of the copper or aluminium wire is called the inductance, and this determines the amount of energy that is stored in the magnetic field. The higher the inductance, the more energy is stored.

The inductor also acts as a filter, blocking out any high-frequency, high-amplitude noise, which improves the voltage and current stability of the system.

The LQH3NPN1R0MMRE is a highly reliable and cost-effective fixed inductor, suitable for a wide range of automotive applications. Its low rated voltage limits it to applications in which the current remains relatively constant such as power factor correction modules, but it is a rugged and reliable component for these applications.
