Fixed Inductors

In this article, we will be discussing an important fixed component, the B78108E1102K009. We will break the component down into its application field and its working principle to gain a better understanding of its use.

The B78108E1102K009 is a common type of fixed inductor. In general, an inductor is a two-terminal device that stores energy in the form of an electromagnetic field. It is mainly used as part of an AC circuit, either to store or to transfer energy.

Application Field

The B78108E1102K009 is typically used as a power inductor in DC-DC power supplies. It is usually made up of a copper coil, core material, and a shield. The core material provides better magnetic permeability, allowing the inductor to have a high inductance value, while the shield isolates the inductor from the surrounding environment to reduce the amount of radiation.This type of inductor is also used in filtering and controlling circuits, such as EMI filters, high-current power supply filtering, and noise suppression. It is also often used to connect multiple stages of power supplies, as its voltage ratings can handle high currents, while its low-profile size enables it to fit neatly into circuit boards.

In addition to these applications, the B78108E1102K009 is also used in resonant power conversion, interference noise mitigation in televisions, and medical devices.

Working Principle

The working principle of an inductor can be easily understood with Faraday\'s Law of Induction. The law states that when a current changes, a voltage is induced in that same circuit. This voltage, or EMF (electromotive force), will induce current flow in the direction opposite to the original current, resulting in an increase in the inductor\'s magnetic field. As the current flows through the coil of the inductor, it creates a magnetic field. This magnetic field will then induce an EMF in the opposite direction to the current, creating an inductive effect. This effect is known as inductance, and it is what makes the inductor work as a passive component in a circuit. As the current changes, the current will either increase or decrease the magnitude of the magnetic field and thus the value of the inductance.

In the case of the B78108E1102K009, the inductor is made up of a copper coil and core material. This makes it highly durable and able to withstand high voltages and currents. The core material also allows the inductor to have a large inductance value.

In conclusion, the B78108E1102K009 is a fixed inductor that is typically used as a power inductor in DC-DC power supplies. It works on the principle of Faraday’s Law of Induction, where a change in current induces a voltage in the same circuit. This voltage, or EMF, will induce current flow in the opposite direction, creating an inductive effect. This inductive effect is responsible for the inductor\'s ability to store and transfer energy in AC circuits.
