Fixed inductors are electrical components used in low frequency to radio frequency circuits. These are usually passive with a coil of wire, and sometimes with core materials within the winding. The goal is to provide inductance to the circuit, which can be important to the overall operation. A fixed inductor can also be used to couple signals between two pieces of circuitry, much like a capacitor, or to protect past circuits from electrical noise, for example when used with a transistor.

The B82476A1224M000 is a particular type of fixed inductor produced by the company TDK. This is a radial-leaded molded inductor with an inductance value of 2.2μH (0.011Ω at 100MHz). Its dimensions are 8.5mm x 12.2mm (excluding leads), and it has a maximum DC current rating of 1.85A with a saturation current of 4A.

The application field of a B82476A1224M000 is fairly broad, as the inductor can be used in a variety of situations. Common usage includes the design of low frequency to radio frequency circuits, such as mobile phone and radio communication circuits, and car navigation systems. It can also be used in power supplies for computers, motor drives, and audio devices. The high saturation current rating of 4A also makes it suitable for power circuits.

The working principle of the B82476A1224M000 is simple yet effective. When current flows through the coil, it produces a magnetic field around the coil that opposes the change in current. This resistance is known as inductance and is directly proportional to the value of the current. The inductance produced by the B82476A1224M000 determines the amount of current that can be passed through the circuit before saturating the inductor.

In conclusion, the B82476A1224M000 is a popular fixed inductor from TDK that can be used in a variety of applications. Its high saturation current rating of 4A makes it suitable for use in power circuits, while its dimensions of 8.5mm x 12.2mm make it suitable for use in portable devices. The working principle of the inductor is the production of an inductance that opposes the change in current, thereby providing a beneficial effect on the overall circuit.
