# IntroductionFixed inductors are widely used in the modern electronics field, especially for the various control systems, such as power supply systems. The current MDMK2020T3R3MM fixed inductors are specifically designed for the highest reliability in those applications. # Application FieldsThe MDMK2020T3R3MM fixed inductors can be widely used in the power supply systems, especially for various low-power and sensitive devices or circuits. It\'s designed to be especially suitable for switch-mode power supplies, frequency inverters, motor drivers, current-limiting circuits, and many other low-power level applications. # Working PrincipleThe MDMK2020T3R3MM fixed non-polarized inductors are designed with a simple well-known principle at its core. It consists of a single wire stretched between two points, usually in the form of a loop. As current flows through the wire, a magnetic field is created around the wire which has the effect of forming a limited current circuit. This limited current path is reversed when the current direction is changed, forming a back-EMF voltage that opposes the change, thus stabilizing the current flow. At low power levels, this back-EMF is enough to limit the current and maintain a more constant desired state for the power supply. At higher power levels, the back-EMF can be supplemented with a resistance in series or a separate battery across the inductor’s terminals to increase voltage stability in the power source. This magnetic field also has the effect of gradually decreasing the current flow as more turns of the wire are applied. This allows the stabilizing effect of the MDMK2020T3R3MM to be tailored specifically to the desired current level, while the number of turns in the wire is easily adjusted in the manufacturing process.# Conclusion The MDMK2020T3R3MM fixed inductors provide powerful and reliable current limiting for low power applications, as well as frequency inverters, motor drivers, and many other current-limiting circuit. Additionally, the current limiting effect of the magnetic field can be easily adjusted in the manufacturing process for a more tailored non-polarized inductor.
