Fixed inductors have wide applications in electronic engineering and are essential components in many circuits. The 155J fixed inductors are high-frequency inductor based on four materials: ferrite core, glass fiber, epoxy resin, and ferrite.

Working principle

155J inductors have a ferrite core and they work by creating a magnetic field near their surface. This magnetic field is created by applying an electrical current to the inductor, which causes electrons to be generated and attracted to the inductor\'s core. As the current moves through the inductor\'s core, a magnetic field is generated. This magnetic field then interacts with the other components in the device, causing them to respond accordingly.

The ferrite core of the 155J inductors is made of a special material that allows more magnetic energy to be stored in the core than other materials. This allows the inductor to store more electrical energy than other inductors, making them very efficient. The efficiency of the 155J inductor is further increased by the use of a glass fiber which is an insulation material. This glass fiber increases the inductor\'s ability to store energy, and thus increases the inductor\'s efficiency.

When the inductor is attached to a circuit, it can act as a current-controlled device. This is because when the current passing through the inductor increases, the inductor will begin to store more electrical energy. This energy can then be used to increase the current passing through the circuit, thus increasing the current in the inductor.

Application Field

The 155J inductors are mainly used in power converters, such as DC-DC converters and AC-DC converters. They are important in power supplies, where they convert the alternating current to direct current, and in DC-DC converters, where they convert one voltage level to another. In addition, they can also be used as a matching device in amplifiers and radio-frequency circuits.

In audio circuits, 155J inductors are commonly used for snubber, DC blocking, and power supply isolation. The inductor acts as a low-pass filter and filters out the high-frequency noise generated by power semiconductor switching circuits. In this way, it prevents audio interference.

The 155J inductors can also be used in sensors and actuators. The inductor can act as the sensor\'s component, as its core stores energy and then releases it to the circuit when the current passing through the inductor increases. This makes them very useful for providing accurate readings in high-frequency applications. In addition, the 155J inductors can be used in actuators, as the increased current can be used to power a motor or other actuator.

The 155J inductor is a versatile component that can be used in a variety of applications. It is important for engineers to understand their working principle and application fields so they can make the best use of these components.
