Fixed Inductors

Fixed inductors are electrical components that store energy in a magnetic field when electricity is supplied. They are found in many applications such as power supplies, switches, motors, generators, and other electronic circuits. The MHQ1005P19NHT000 is a fixed inductor designed to help with power management. This article will discuss its field of application and working principle.

Application Field

The MHQ1005P19NHT000 inductor is suitable for circuits that require high current, where the voltage ripple is limited to a minimum. It is suitable for use in conventional linear and switch mode power supplies, as well as high voltage equipment. More specifically, it can be applied in PFC boost or buck converters, telecom DC-DC converters, and motor control electronics.

Working Principle

The working principle of the MHQ1005P19NHT000 is based on Faraday’s law, which states that a changing magnetic field induces an electromotive force (EMF) in a conductor. When an alternating current is applied to the inductor, it generates a magnetic field which induces an EMF in the conductor. The EMF, in turn, generates an opposing current flow, which opposes the flow of the applied current. This opposing current flow is known as inductor current.The magnetic field generated by the MHQ1005P19NHT000 is proportional to the applied current and is characterized by its inductance value. The inductance value determines the amount of resistance the inductor offers to the flow of current. In other words, higher inductance values correspond to higher inductor impedance and lower current flow. This is useful in applications that require high current flows when the current is excessively high.

Conclusion

The MHQ1005P19NHT000 is a fixed inductor used in many applications, such as power supplies, motor control electronics, and DC-DC converters. Its working principle is based on Faraday’s law, which states that a changing magnetic field induces an electromotive force in a conductor. The inductance value determines the amount of resistance offered to the flow of current. As such, it is useful for limiting current flows when the current is too high.
