Fixed Inductors

Fixed inductors are components used to efficiently store and transfer energy in the form of electric current. These components are widely used in products like automotive systems, consumer electronics, medical devices, power supplies, and many other industrial and commercial applications. In this article, we will discuss the application field and working principle of the S1812-222G inductor.The S1812-222G is a self-supporting, leaded, fixed, high-current RF inductor designed for high-current RF applications in ground-planed and printed-circuit-board applications. This component is ideal for applications such as mobile phones, consumer electronics, and automotive to increase the efficiency of inductors in high-current RF applications. It has a low profile of 12.0mm × 6.8mm × 8.4mm to ensure secure mounting on board.The S1812-222G is rated up to 200A with a maximum operating temperature up to 200C. Its DC resistance is 0.3mohm and it provides high power handling capabilities with a rated inductance of 0.82µH. This inductor also has a wide operating frequency range of up to 1MHz and provides a higher ratio of inductance to DC resistance compared to other inductors in its class.In addition, the S1812-222G features an ultra-thin profile, low DCR, high-current capacity, and wide operating frequency range that ensures this inductor is ideal for high-frequency, high-current applications. It has a maximum current of 2.5A and a saturation current of 0.1A. The S1812-222G has a very good self-resonance frequency and it is highly reliable with excellent humidity and electrical performance since it has a high rated humidity level above 80%.The S1812-222G works on the principle of a coil of wire carrying current. The current passes through the coil, creating an electromagnetic field which induces an electric current in the coil. The induced current produces an opposing electric field, which in turn opposes the flow of current, resulting in a drop in voltage and an increase in current across the inductor. This drop in voltage and increase in current causes the inductor\'s output to fluctuate in an oscillatory fashion, creating an alternating current.To reduce the losses in a coil, the S1812-222G inductor is designed to have a high permeability core material. The core material is chosen to minimize the skin effect, which occurs when electric current flows through the small diameter conductor. This inductor also utilizes a high quality, self-shielding material to reduce electromagnetic noise.The S1812-222G is designed to provide high power delivery with high efficiency and high frequency operation. It is also very reliable and can be used in a variety of applications, including automotive, consumer electronics, and medical device. As a result, the S1812-222G is a popular choice for high-performance, high-current RF applications.
