MILS1812-105K Application Field and Working Principle

Fixed inductors, as their name indicates, are those inductors with fixed inductance values. Frequently used in switch-mode power supplies, the MILS1812-105K is one of the most popular types of fixed inductors. This section examines the application field and working principle of the MILS1812-105K.

Applications

The MILS1812-105K is commonly used for a variety of electronic applications. It\'s often used in high-frequency switch-mode power supplies for powering DC-DC converters, voltage regulators, buck converters, boost converters, and more. It also has applications in battery charging circuits and can be used as an output filter for stabilizing the output voltage.

Working Principle

An inductor is an electrical component that stores energy in the form of a magnetic field when a current passes through it. The MILS1812-105K is a fixed inductor, meaning that it has a fixed inductance value when current passes through it. This inductance value remains constant, even when the current or voltage changes.When current is applied to the MILS1812-105K, a magnetic field is created, and the inductor stores energy in the form of this magnetic field. As the current increases, the inductor stores more energy, thus causing a voltage drop across the inductor. This voltage drop is inversely proportional to the rate of change of current. When the current decreases, the magnetic field dissipates, and the energy stored in the magnetic field is released. This energy then flows back into the circuit, creating a voltage spike.

Conclusion

The MILS1812-105K is a popular type of fixed inductor that is used in a variety of electronic applications. It works by storing energy in the form of a magnetic field when a current passes through it, and the inductance value remains constant even when the current or voltage changes. The MILS1812-105K is commonly used in high-frequency switch-mode power supplies for powering DC-DC converters, voltage regulators, buck converters, boost converters, and more. It is also often used in battery charging circuits and as an output filter for stabilizing the output voltage.
