Fixed inductors are a common form of electrical inductors, characterized by their physical structure and design. The B78108S1224J009 is an example of a fixed inductor, and in this article, we’ll discuss its application field and working principle.

Fixed inductors are very versatile, used in many different applications in engineering. Commonly found in power supplies, audio amplifiers, and switched-mode power supplies, fixed inductors can also be used in the detection of electric current in analog circuits, and can be used as suppressing devices to filter out high-frequency or noisy signals.

The B78108S1224J009 is a high-precision inductor, widely used for a variety of applications. It has a large coil inductance of 19 mH, a rated current of 2A, and a low resistance value of 0.16R. The inductor is also extremely stable, with a high temperature coefficient of 0.3 %/K and a Q factor of 90.

The working principle of a fixed inductor is based on Faradays’ law of induction. This law states that when a conductor is moved through a magnetic field, a voltage is induced in the conductor proportional to the rate of change of flux. Put simply, this means that when electric current passes through an inductor, it creates a magnetic flux that induces an electric current, and this current is proportional to the rate of change of the magnetic flux.

In the case of the B78108S1224J009, the electric current passes through the coils, creating a magnetic field. As the current varies, the magnetic field changes, inducing a new current in the coils. This current is proportional to the rate of change of the magnetic field.

The B78108S1224J009 is a very versatile fixed inductor and can be used in a variety of applications. It is particularly useful in power supplies, audio amplifiers, switched-mode power supplies, electric current detection, and signal filtering. It is also highly stable and reliable, with a low temperature coefficient and high Q factor.

To sum up, the B78108S1224J009 is a high-precision fixed inductor, widely used in a variety of applications. It works on the principle of Faradays\' law of induction, creating an induced current in the coils proportional to the rate of change of the magnetic field. It is particularly useful in power supplies, audio amplifiers, switched-mode power supplies, electric current detection, and signal filtering and has a low temperature coefficient and high Q factor.
