Introduction

Fixed inductors are common passive components which are used in a variety of electrical circuits. They consist of a coil of copper wire wound around a core, usually a ferrite material. These inductors are widely used and come in a variety of shapes and sizes, as well as in different values of inductance. One example of a fixed inductor is the BRC2518T470K, which is an inductor with a 47 microhenry inductance rating.

Application Field

The BRC2518T470K fixed inductor is typically used in DC to AC inverter circuits, switching power supply circuits, and high frequency transformer circuits. It can also be used in other applications such as power supplies, amplifiers, and RF amplifiers. Its high impedance combined with its low DC resistance allows it to be used in a variety of AC and DC circuits.

Working Principle

The BRC2518T470K fixed inductor has a 47 microhenry rating, which means that it is able to produce 47 microhenries of inductance when supplied with a current. Inductance is a property of an inductor which can be thought of as the opposition to change in current, which increases with the rate of current change. This means that the inductor stores electrical energy in an alternating current as the current changes direction.When the inductor experiences an alternating current, a magnetic field is generated which induces a voltage in the opposite direction. This voltage opposes the current, and is known as back emf. This back emf, or counter voltage, is the voltage which causes the inductor to resist changes in current. This resistivity is known as inductance.

Conclusion

The BR2518T470K fixed inductor is a versatile component which is used in a variety of AC and DC circuits. It has a 47 microhenry inductance rating, which gives it a high impedance and low DC resistance, making it ideal for use in applications such as power supplies, amplifiers, and high frequency transformer circuits. Its working principle revolves around the inductor\'s ability to store electrical energy in an alternating current as the current changes direction, as well as to resist changes in current through back emf or counter voltage.
