Introduction

Fixed inductors are an important type of electronic component used in a wide range of applications. The 1331-472J is one example of a fixed inductor that can be found in many electronic circuits. This article will discuss the application field and working principles of the 1331-472J fixed inductor.

Application Field

The 1331-472J fixed inductor is mainly used for applications such as filter and chokes. Filters and chokes are used in electronic power supplies, lighting circuits, and sound filtering in audio equipment. The inductor is used to reduce the high frequencies in the circuit and create a smoother sound. It can also be used to create power supplies with different current levels.

Working Principle

The working principle of the 1331-472J is based on the principle of inductance. An inductor is an electronic component that stores energy in a magnetic field. When current passes through the inductor, a magnetic field is generated which produces an induced voltage. This induced voltage opposes the applied current, and the amount of current that can pass through the inductor is reduced.The 1331-472J consists of two coils wound around a central core, which is usually made of ferrite or iron powder. Each coil is connected to two separate terminal pins. When current is applied to the inductor, a magnetic field is formed around the core. This magnetic field induces a voltage in the second coil, creating an opposing force to the current in the first coil.

Conclusion

The 1331-472J is a fixed inductor designed for use in applications such as filter and chokes. It works on the principle of inductance, in which a magnetic field is created around a ferrite or iron powder core. This magnetic field induces a voltage in a second coil, which opposes the current in the first coil. By doing so, the amount of current that can pass through the inductor is reduced.
