Fixed inductors are components whose inductance value cannot be changed, and the NRH2412T100MNGH is an example of this type of component. This surface mount fixed inductor is optimized for operations in an environment between -40°C and +85°C. The component is manufactured using a ferrite core and copper magnetic surface to provide high current operation and low DCR. It also contains a shielded construction that allows it to be installed in non-shielded types of equipment.

Application Field of the NRH2412T100MNGH

The NRH2412T100MNGH is especially suitable for use in applications like decoupling, filtering, and oscillators, especially in radio and television sets, VRLA and Li-ion battery packs, as well as in any other circuit requiring a stable quality of inductors over a broad range of temperatures.

This specific inductor can handle high current up to 2A, and as such it is very suitable for high-power applications as well as LED Backlighting, allowing it to deliver efficient and stable current when connecting an AC/DC power supply to an LED array.

It is also suitable for designs requiring an inductance of 10nH, so that the need for bulkier polarized inductors is eliminated. The capacitors and resistors can be inserted in the same footprint that was formerly necessary only for the big, polarized inductors. Furthermore, reducing the required space for the connectivity makes the inductors suitable for smaller form factor designs, such as laptop computers, consumer electronics, handheld devices and related audio components, among others.

Working Principle of the NRH2412T100MNGH

The NRH2412T100MNGH works on the principle of Faraday\'s law of induction. This law states that an induced electromotive force (emf) is generated in a circuit whenever the magnetic flux linked with the circuit changes. The induced emf is given by the following equation: E=-N(Φt/Δt), where E stands for the induced electromotive force, N for the number of turns in circuit, Φ is the magnetic flux, and Δt for the time rate of change of the flux.

When a NRH2412T100MNGH is placed in a circuit, current is passed through it and a magnetic field is created. The perpetual circulation of current in the circuit generates a magnetic flux through the inductor. The magnetic flux passing through the inductor core is concentrated by a ferrite material, which causes the flux to be maximized and a higher magnetic field to be created. This higher magnetic field gives rise to an induced electromotive force which opposes the original applied voltage that passes through the inductor.

The higher the magnetic field intensity, the higher the opposition of the voltage of the inductor be. This means that the higher the current applied to the inductor, the higher the induced electromotive force will be, leading to the ‘smoothing’ of the voltage supplied to the circuit. In other words, the NRH2412T100MNGH helps reduce the ripple formed by AC- to DC power supplies, governing power flow to the circuit’s components and aiding in their safe operation.
