SP1812-103K

Fixed Inductors

The SP1812-103K inductor is a component of a power supply device that fixes the device and its electrical characteristics. It is used to maintain a constant average current through the windings throughout operation. It is an important component in controlling the amount of power being supplied to a device, and is often found in low power devices. This type of inductor is typically used in switched mode power supplies, power factor correction circuits, audio amplifiers, and low voltage regulated power supplies.

The working principle of the SP1812-103K inductor is based on electromagnetic induction. This principle states that when a coil passes through an alternating magnetic field, electric current is produced. This phenomenon occurs when an inductor is connected to an electrical circuit. When an alternating current is passed through a coil of wire, a varying magnetic field is generated. An electric current is then induced in the adjacent winding which is in the self-induced coil.

The SP1812-103K series inductors are designed to provide a fixed inductance and a lower inductance tolerance for a given current. Additionally, the series offers improved self-heating properties and provides a wide output current range with minimal ripple. The inductors can function as either a current limiting or current-sensing element, depending on the application, providing fast and reliable protection against sudden surges or short-term overloads.

The core of the SP1812-103K inductor is composed of high-permeability ferrite material, which increases the inductor’s efficiency and minimizes noise. The inductor also features an electromagnetically shielded magnetic circuit, which helps to reduce cross-talk and electromagnetic interference. Additionally, the self-heating properties of the inductor make it suitable for use in environments with limited space.

Overall, the SP1812-103K series inductors are ideal for use in low voltage power supplies, audio amplifiers, switched mode power supplies, and power factor correction circuits. The inductors are efficient, reliable, and versatile, making them a great choice for use in a wide range of applications.
