Fixed inductors are components that store energy in the form of an electric current. Generally, they are in the form of a coil wrapped around a ferromagnetic core, which works to increase the inductance of the device. The 1812R-274H is one such fixed inductor, designed as an electromechanical component that is typically used in power electronics applications. Here, we will discuss its application field and working principle.

Application Field

The 1812R-274H inductor is well suited for power electronics applications that require a high degree of temperature coverage. Specifically, it is often used in applications that require higher inductance values and power ratings than other similar devices, such as in switch-mode power supplies. It is also suitable to be used in automotive electronics, wireless charging systems, and various types of motor controls.

Working Principle

As discussed earlier, the 1812R-274H is an inductor that uses a ferromagnetic core to increase its inductance. This works to store energy in the form of an electric current. When a current is applied to the device, it produces an opposing voltage in proportion to the applied current. This opposes the flow of the current and can effectively limit the amount of current that flows through the device. As a result, the 1812R-274H is able to act as a voltage regulator or current limiting device.

The device also operates by utilizing the principle of electromagnetic induction. When a voltage is applied to the device, an inductive or reactive voltage is created, resulting in a magnetic field around the device. This magnetic field radiated by the device reduces the electromagnetic interference with other components in the system, thus preventing the possibility of damaging electrical fuses or causing other forms of disruption.

Conclusion

The 1812R-274H fixed inductor is a versatile device designed for power electronics applications. It functions by storing energy in the form of an electric current, utilizing both the principle of electromagnetic induction and its ferromagnetic core to provide an opposing voltage and reduce electromagnetic interference. Due to its high power ratings and temperature tolerance, it is often used in automotive electronics, switch-mode power supplies, wireless charging systems, and various types of motor controls.
