Fixed Inductors

Inductors are passive components that interact with an electrical current to generate a magnetic field. When the current moves through the inductor, an induced voltage and current is created according to Faraday\'s Law. The voltage produced by the inductor works against the power source and limits the amount of current so that it remains constant. Inductors come in a variety of shapes and sizes, ranging from small surface-mount parts to large heavy-duty coils. One type of fixed inductor, known as the SP1812-104G, is often used in power supply and industrial control applications. This article will explain the working principle of the SP1812-104G and discuss its common applications.

Working Principle of SP1812-104G

The SP1812-104G is a fixed inductor, which means that it has a fixed value and does not require tuning or adjustment. It is constructed with wire wound tightly around a ferrite core, forming a coil. As current passes through the coil, it generates an induced voltage and current. The size of the inductor determines the magnitude of the voltages and currents being generated. The SP1812-104G has a maximum rated current of 1.0 A and a maximum rated voltage of 400 mV. These numbers indicate that the inductor is able to handle relatively high levels of electrical current and produce large induced voltages and currents.

The main difference between the SP1812-104G and other fixed inductors is its core material. While other inductors use a ferrite core, the SP1812-104G uses an iron-powder core. This core material enables the inductor to be much smaller than similar components with a ferrite core. It also helps to reduce eddy current losses in the inductor, resulting in better efficiency and higher frequency operation.

Applications of SP1812-104G

The SP1812-104G is a versatile inductor that can be used in a variety of power supply and industrial control applications. Its relatively small size and high power handling capability make it a good choice for high-density applications. It can also be used in place of a transformer in applications where size is a factor. Some of the common applications include:

• Low voltage and high-power switching power supplies.
• Switch mode power supplies.
• DC-to-DC converters.
• Power factor correction circuits.
• Motor and generator controls.
• DC choke.
• Filtering circuits.

The SP1812-104G is a reliable and efficient inductor that is suitable for a variety of power supply and industrial control applications. It is easy to use, provides a high level of efficiency, and has a compact size. As such, it is an ideal component for any electrical application requiring a high-power inductor.
