Introduction

The NRH2412T1R5NNGH is a fixed inductor coming from the family of MECHANICAL-SWITCHED INDUCTOR SWITCHES, usually referred to as MSI. This type of inductor is a fixed component which is implemented in various types of power electronics applications and it is largely used to provide reliable and controllable inductance in the application.

What is a Fixed Inductor?

An inductor is an electrical component which stores the energy in the form of a magnetic field when an AC signal or current is applied to it. A fixed inductor is an inductor which has a predetermined amount of inductance over its operational range and cannot be altered. Fixed inductors are mainly used for power electronics applications such as lighting, audio, power supplies, motor and HVAC control systems.

NRH2412T1R5NNGH Application Field and Working Principle

The NRH2412T1R5NNGH fixed inductor is a current mode inductor with an inductance range of 0.22 to 2mH, maximum current rating of 7.2A and a resistance of 0.45mΩ. This type of immobilised switch-mode inductor is suitable for use in applications such as LED lighting, DC/DC converters, Class-D amplifiers, motor controllers and 1D-TFT displays. The NRH2412T1R5NNGH is a current mode fixed inductor where the active element of the inductor is wound onto a chip shaped metal core. The core consists of a number of turns coupled to a magnetic material which intensifies the flux linking the turns to form a closed loop. When a current is applied, the core produces a magnetic field which stores the energy in the form of fluctuating magnetic flux. The shape of the coil determines the inductance of the inductor.

Conclusion

NRH2412T1R5NNGH is a type of fixed inductor known as Mechanically Switched Inductor (MSI). This inductor is suitable for a wide range of power electronics applications including LED lighting, DC/DC converters, Class-D amplifiers, motor controllers and 1D-TFT displays. The inductor operates on a current mode where the inductor is formed by winding a number of turns onto a chip shaped metal core and coupling them to a magnetic material. This technique allows the inductor to reach a predetermined amount of inductance with a resistance of 0.45mΩ and a maximum current rating of 7.2A.
