1210R-100J

Fixed Inductors

Fixed inductors are a type of electrical component used in circuits where storage of energy is required in the form of magnetic fields. They consist of a core material, usually some form of ferromagnetic material, and a coil of wire that generates a magnetic field when electricity is passed through it. The type of core material, number of turns of wire, and type of wire used all affect the strength of the magnetic field and electrical properties of the inductor. Generally, as the core material gets larger and the number of turns increases, the inductor\'s ability to store energy increases.

1210R-100J Application Field and Working Principle

The 1210R-100J inductor is a surface mounted inductor designed for use in high frequency circuits. The core material is ferrite and the coil is made of copper wire. The inductance of the 1210R-100J is 100 uH with a maximum rated direct current of 1 A. It has a maximum rated ripple current of 500 mA and an inductance tolerance of 10%.

The main application field of the 1210R-100J is high frequency analog circuits, such as radios, television, and amplifiers. It is also used in industrial applications for controlling motors, as well as in high frequency switching power supplies. As for its working principle, when an alternating current is passed through the inductor, the coil generates a magnetic field which induces an EMF (electromagnetic force) in the core. This EMF opposes the primary current by generating an oppositely-directed current, which is known as the back EMF.

The 1210R-100J has a low equivalent series resistance (ESR) and low electrical losses, meaning it can be used in applications where efficiency is important. It also has a very high power to size ratio, making it a good choice for applications where space is a constraint. Lastly, it has a very high self-resonant frequency, meaning it can be used in circuits operating at higher frequencies.
