CAL45VB3R9K

Fixed Inductors

The CAL45VB3R9K is an example of a fixed inductor, which is a component used in electrical circuits to store energy in the form of a magnetic field. This type of inductor has an exact form and a specific electrical value. It has a core of solid iron, and it comes in a variety of shapes and sizes. The size and shape of the iron core may vary depending on the application.

There are two different types of fixed inductors, which are air-core and ferrite-core. Air-core inductors consist of a wire wound around an air core, while ferrite-core inductors are composed of a ferrite core that is wrapped in wire. The shape of the ferrite core affects the inductance value that is produced. The larger the size, the higher the inductance value.

The CAL45VB3R9K fixed inductor has a rated inductance of 4.5mH, with an operating temperature of -40°C to +85°C. It has a high temperature coefficient of 0.2%. It is also rated for peak currents of up to 10A. The CAL45VB3R9K can be used in a variety of applications, such as switching power supplies, LED lighting, and motor control.

Working Principle

The working principle of a fixed inductor is simple. When a voltage is applied across its terminals, a magnetic field is created inside the inductor. This field then stores energy, which is then released when the voltage is removed. This action is known as inductance, and it is what makes fixed inductors useful in electrical circuits.

When an alternating current flows through an inductor, it induces a voltage in the inductor according to Faraday’s law. This induced voltage opposes the applied voltage, which causes the current flowing through the inductor to decrease. This effect is known as inductive reactance, and the size of this reactance is proportional to the frequency of the alternating current. By varying the frequency, it is possible to control the amount of current flow through an inductor.

In addition, a fixed inductor can be used as a filter, allowing only the desired frequency of alternating current to pass through it. This is known as a high-pass filter, since high-frequency signals are allowed to pass while lower-frequency signals are blocked. This filtering effect can be used to isolate signals in a circuit, or to reduce noise and interference.

The CAL45VB3R9K fixed inductor can be used in a wide variety of applications due to its high temperature coefficient and peak rated current. It is suitable for use in high-frequency circuits such as LED lighting and motor control. It can also be used in filtering applications, where it can help to reduce noise and interference. Overall, it is a versatile component that can be used in a variety of electrical circuits.
