Fixed Inductors

The S1812-332G is a fixed type inductor that is widely used in many applications. Its construction is extremely robust and durable. It is a reliable component with a long service life, making it an ideal choice for use in a variety of applications.

Application Field:

The S1812-332G is suitable for use in a wide range of applications including power supply regulation, filtering, noise suppression, heavy load switching, and motion control. It can also be used in automotive, industrial and medical applications as well as in communications and networking. The inductor can be used as a part of a bridge rectifier circuit, a flyback transformer, or an autotransformer in power supply circuits. It is also commonly used in power inverters and variable frequency drives (VFDs).

Working Principle:

The operation of the S1812-332G is based on Faraday\'s Law. This states that when a varying current is applied to a conductor, a changing magnetic flux will be generated around the conductor, and this will induce an electromotive force in its vicinity. This EMF generated will oppose the current, and the intensity of the generated EMF will depend on the magnitude of the current, the rate of its change, and the number of turns of the coil. In the case of the S1812-332G, the winding consists of a single layer of enameled copper wire, providing a high inductance value and low capacitance. This allows it to work effectively over a wide frequency range, and without producing nuisance noise.

The inductance of the S1812-332G can be affected by changes in temperature, current, and voltage. A temperature compensation technique may be required in some applications to maintain a consistent inductance value. When used as part of a circuit, the inductor must be properly matched with other components and checked for lead length, wire size, and voltage rating to ensure the desired performance.
