1008-820J

Fixed inductors are electronic components used in electronics and electrical engineering circuits. The 1008-820J is one of the most widely used fixed inductors due to its application in a wide range of electronic circuits, as well as its relatively compact form factor. In this article, we will explore the application field and working principle of the 1008-820J fixed inductor.

The 1008-820J fixed inductor is a surface mount component designed for use in high-frequency, medium to low power circuits. It has a compact physical form factor of just 1.0 × 0.8 millimeters, making it suitable for integration into high density circuit boards. Additionally, the 1008-820J can operate over a wide range of temperature, up to a maximum of 125°C.

The 1008-820J fixed inductor is made of a ferrite core and a copper wire wound around the core. The ferrite core provides the magnetic field necessary for the inductor\'s function, allowing it to store energy. The coil and core act together to pass through a sustained signal. The coil also acts as an electrical conductor, allowing the inductor to pass both AC and DC signals.

The main application field of the 1008-820J fixed inductor is high frequency, medium to low power circuits. It can be used in power supplies, switching power amplifiers, audio amplifiers, and digital signal processors. The 1008-820J is also suitable for use in filter circuits, rectifiers, buck and boost regulators, and for interference suppression.

The working principle of the 1008-820J fixed inductor is relatively simple. When an alternating current (AC) is applied to the inductor, it magnetizes the ferrite core and creates a magnetic field. This magnetic field stores electrical energy and is able to release it when the current is removed. This stored energy flows through the inductor in the form of a sustained current, which can be used to power other components in the circuit. The amount of energy stored is dependent on the size of the coil and the amount of current passed through.

In conclusion, the 1008-820J fixed inductor is an ideal component for use in high frequency, medium to low power circuits. It is a compact surface mount device, that has a wide operating temperature range and offers excellent performance. The core and coil of the 1008-820J combine to form an inductor that can store energy and release it in the form of a sustained current.
