Fixed Inductors: HK212556NJ-T Application Field and Working Principle

A fixed inductor is an electronic component that consists of a coil of wire wrapped around a core of ferromagnetic material. It stores energy in a magnetic field generated in the coil when current flows through it. The inductor\'s stored energy is released once the current flow stops, and it can be used in a variety of applications. The HK212556NJ-T is one such fixed inductor that is widely used in various fields, and this article will discuss its application fields and working principle.

Application Field of HK212556NJ-T

The HK212556NJ-T is a surface-mount, high-current, shielded power inductor manufactured by Murata. It has a low DC resistance and is used in various applications such as power supplies, DC-DC converters, filtering, and RF circuits. It can also be used as an input/output choke in switching converters.

The HK212556NJ-T is suitable for applications that use high-current up to 3A. In addition, it exhibits excellent ripple current characteristics and ensures stable performance even under high-frequency switching operations. It is designed for use in medium-sized equipment, such as servers, graphics cards, hard disk drives, and mobile phone baseband chips.

Working Principle of the HK212556NJ-T

The working principle of the HK212556NJ-T is the same as any other inductor. When current flows through its wire coil, a magnetic field is created. The magnetic field increases the amount of energy stored in the coil and the voltage across the coil. This increase in voltage helps limit the current flow. By doing so, it can be used to filter ripple from the load voltage, suppress ringing in switching circuits, and stabilize DC-DC converters.

Moreover, the HK212556NJ-T is designed to minimize the influence of parasitic capacitance and inductance on the operation of switching circuits. Its core material is made of permalloy, which is highly permeable and offers low core loss. This ensures that the HK212556NJ-T can operate at high frequencies, up to 1MHz, without significant losses.

Conclusion

The HK212556NJ-T is a high-current, shielded power inductor manufactured by Murata. It is suitable for high-current applications such as power supplies, DC-DC converters, filtering, and RF circuits. It is designed to minimize the influence of parasitic capacitance and inductance on the operation of switching circuits. The HK212556NJ-T can operate at high frequencies, up to 1MHz, without significant losses.
