Fixed inductors are electronic components utilized for the purpose of aiding in signal conditioning or power-supply filtering. 1812R-153G is just one of these fixed inductor components. This article will provide an in-depth discussion of its application field and working principle.

Application Field

1812R-153G is a low profile, shielded multilayer wound surface-mount fixed inductor designed for use in consumer electronic products. It offers high inductance in a small package, with low DC resistance and low DC resistance variation. It is perfect for applications such as broadband amplifiers, RF amplifiers, cellular phones, GPS systems, communication systems, telecommunication systems, Ethernet systems, and wireless local area networks (WLAN).

The shielded construction helps minimize electrical noise and interference, while also providing additional protection for the inductor. 1812R-153G features an Inductance-to-resistance (ITR) ratio of 3:1 and high current conduction, making it very reliable and efficient for high frequency and power applications. The shield is also designed to prevent the core from shorting out when exposed to high voltage or high temperature.

Working Principle

An inductor works on the principles of Faraday\'s law of induction. This law states that when an electric current is passed through a conductor, an electromagnetic field is created around the conductor. When this field interacts with a nearby magnetic material, such as a ferromagnetic core, it causes the material to vibrate and generate a magnetic flux. This magnetic flux then generates a current in the conductor, which is known as the inductance, and can be measured using an inductance meter.

1812R-153G, specifically, works by passing the electric current through a coil of insulated wire. This coil, which is known as the primary winding, is wrapped around a ferromagnetic core, which causes the primary winding to act like a magnet. When the primary winding is exposed to an external magnetic field, it will induce a current in a second coil, known as the secondary winding. This secondary current can then be measured with the inductance meter.

Conclusion

1812R-153G is a low profile, shielded multilayer wound surface-mount fixed inductor designed for consumer electronics. It features a 3:1 ITR ratio, high current conduction, and a shield to prevent core shorting. Its working principle is based on Faraday\'s law of induction, whereby electric current passed through a primary winding wrapped around a ferromagnetic core induces a current in a secondary winding.
