Fixed inductors have a wide range of application fields and are generally used in communications, consumer electronics, automotive, aerospace, lighting, etc. The 108R-104J series, one of the most popular models of the fixed inductors, can be applied in the same areas. The 108R-104J series comprises various types of devices, specified for different automobile and consumer electronics. The device is used for boost and buck converters, LED drivers, CFL and LED lighting, as well as other applications.

The 108R-104J series is a type of fixed inductor. It is constructed using a copper core or a hollow iron core, encased in a ferrite shell. The devices differ in parameters such as inductance, maximum current, dimensions, core shape, metallization, etc. The inductance of the devices range from 1μH to 360mH and the maximum current is up to 39A.

The working principle of the 108R-104J series is based on the linear energy storage concepts in magnetic fields. According to the Faraday’s law, the inductance of the device will increase or decrease in accordance with the magnitudes and the polarities of the current and the flux. As the current staying in the coil increases, the magnitude of the inductance increases. This means that the 108R-104J series can maintain a high level of inductance and have a fast response time, even though current is flowing through them.

The 108R-104J series also contains magnetic devices with different forms such as single-layer or multi-layer with or without shielding. This diversity of shapes makes the 108R-104J devices highly applicable for various conditions.
