Fixed Inductors: MDKK2020T150MM Application Field and Working Principle

A fixed inductor is a passive component that creates an electric current when put into a magnetic field. It is used to store energy in the form of a magnetic field and convert it to electrical current. It works in a variety of applications, such as power supplies, DC-DC converters, and more. The MDKK2020T150MM is one such fixed inductor, and it is a Ferrite core chip inductor with a built-in shield design. Here, we will discuss the application field and working principle of the MDKK2020T150MM.

MDKK2020T150MM Application Field

The MDKK2020T150MM is generally used in high power systems where large currents are required. It is used in various power supply systems, including switch mode power supplies, flyback converters, and DC-DC converters. The inductor can handle high current spikes, low AC resistance, and good thermal resistance. It is also used in snubber circuits, buffering filters, and electromagnetic interference suppression. With its high power handling capability and low ESR, the MDKK2020T150MM is an ideal inductor for these applications.

MDKK2020T150MM Working Principle

The basic principle behind the MDKK2020T150MM is that of a self-induction property of an inductor. In other words, when a current flows through an inductor, a magnetic field is formed around it. This magnetic field has a certain periodicity which is proportional to the amount of current flowing through it. The rising and falling of the magnetic field induces a voltage in the inductor which is equal to the magnetic flux’s change rate. This induced voltage opposes the original current, thus causing the amount of current to remain the same. This phenomenon is known as a self-induction property.The MDKK2020T150MM has a very low ESR value which means it can produce high peak currents with minimal voltage distortion. It also has a high saturation current, which gives it the ability to handle high current demands. Furthermore, it is built with a high temperature ferrite core material which has good thermal conductivity and low parasitic capacitance, ensuring reliable performance.

Conclusion

The MDKK2020T150MM is a fixed inductor used in many power systems. It has a high power handling capacity, low ESR, and good temperature resistance. Its application field includes switch mode power supplies, DC-DC converters, snubber circuits, buffering filters, and electromagnetic interference suppression. Its consistent performance is due to its self-inductance property, which is based on the effects of a magnetic field on current flow. With its features, it is ideal for various applications that require reliable power.
