Fixed Inductors – MHQ1005P9N5JTD25 Application Field and Working Principle

Fixed inductors, which are generally referred to as “coils”, are passive devices that are made of one or more loops of insulated magnetic material. Inductors can be broadly classified into two types: the ferrite bead inductor and the coil inductor. The former is generally made of ferrite material with air core, while the latter is a coil winding around a ferrite core. The MHQ1005P9N5JTD25 is a fixed type inductor that falls into the latter category. This article will take a closer look at its application field and working principle.The MHQ1005P9N5JTD25 is a high-current, low-profile, fixed inductor capable of handling up to 10A continuous, and up to 20A peak. It has low DCR (< 0.30ohms) and Q (up to >20) and comes in a shielded SPQ package with an insulation sleeve for extra protection. Its primary applications include switch mode power supplies, hot swap/hot plug applications, general DC-DC converters, overvoltage protection circuitry, and power switching systems.The MHQ1005P9N5JTD25’s working principle is based on the same physical laws as that of an AC transformer. The inductor works by converting an alternating current (AC) to a steady direct current (DC). This is accomplished by passing an alternating current through the inductor, where it induces a voltage difference between the two ends of the circuit. This voltage difference is the “back EMF” which opposes the current flowing through it. As a result, the current flowing through the inductor is reduced, and the remaining current is now “steady”.The amount of voltage induced depends on the inductance of the inductor, as well as the rate of change of the current that flows through it. The higher the inductance, the more opposition or “back EMF” is created, and the less current is allowed to flow. The MHQ1005P9N5JTD25 is designed to work effectively at switching frequencies of up to 2MHz, and it is ideal for use with USB Type-C™ connectors.In summary, the MHQ1005P9N5JTD25 is a fixed type inductor used in various power systems, and its working principle is based on the same physical laws as that of an AC transformer. The inductor works by converting an alternating current to a steady direct current, by inducing a voltage difference due to the opposition or “back EMF” created by the inductor’s coil windings. It is an ideal component for use in switch mode power supplies, hot swap/hot plug applications, general DC-DC converters, overvoltage protection circuitry, and power switching systems. Its high current rating makes it a great choice for use with USB Type-C™ connectors.
