Fixed Inductors

Fixed inductors are electrical components designed to store energy in the form of a magnetic field when current passes through it. One such inductor is the MHQ1005P40NHTD25. This paper will look at the application fields and working principles of this component.

Application Field

The MHQ1005P40NHTD25 is a high-inductance, leaded fixed wire-wound inductor. It is designed for use in a variety of applications, including DC-DC converters, switching applications, power supplies, and alternative energy systems. It is also used in electronic clock systems, DC motor controls, and low-voltage analog circuits. The device is rated for an operating temperature range of -15°C to +85°C.

The device features a ferrite core material, a tinned copper-clad steel wire winding, rated voltage up to 400V, rated current up to 5.6A, ripple current up to 10.7mArms, and inductance range between 2.2µH and 10μH.

The MHQ1005P40NHTD25 is relatively small in size, with dimensions of 10.0 x 5.0 x 6.5mm. This means it does not take up much space in printed circuit board (PCB) designs, making it a popular choice for space-constrained systems. It also features an exposed metal pad which can be used for better thermal dissipation and improved reliability.

Working Principle

The working principle of the MHQ1005P40NHTD25 is fairly simple. It works by creating a magnetic field when an electric current passes through it. The magnetic field that is generated will then induce an opposing current in the device, which results in a voltage drop across the inductor. This voltage drop is what leads to the energy storage in the form of a magnetic field. As the current increases, the strength of the magnetic field increases as well, resulting in higher voltage drops and more energy storage.

The MHQ1005P40NHTD25 also features a ferrite core material, which helps increase the inductance of the device. The core material acts as a magnetic reservoir that can store more magnetic flux for longer periods of time. This ensures that the inductor is able to handle higher current levels without saturating and experiencing high voltage drops.

In addition, the device also features a tinned copper-clad steel wire winding. This wire winding is designed to reduce eddy current losses by acting as a barrier between the ferrite core and the external circuit. This helps improve the efficiency of the inductor and reduce losses due to heat.

Conclusion

The MHQ1005P40NHTD25 is a popular fixed inductor designed for a wide range of applications, including DC-DC converters, switching applications, power supplies, alternative energy systems, and more. It features a relatively small size, a ferrite core material, and a tinned copper-clad steel wire winding, all of which make it an ideal choice for space-constrained systems. Moreover, the MHQ1005P40NHTD25 works by creating a magnetic field when an electric current passes through it, storing energy in the form of a magnetic field and inducing a voltage drop in the process.
