S1812-223H

Fixed inductors, otherwise known as inductors, are a type of electrical component which stores energy in the form of electromagnetic field. They are commonly used in electrical circuits and their energy is used to induce current or provide impedance in AC circuits. The S1812-223H is a series of fixed inductors designed for electromagnetic compatibility (EMC) applications. This series of inductors has an inductance range from 0.47 μH to 510 μH and can operate up to a rated temperature of 125°C with a maximum current of 525 mA.

The S1812-223H is designed to meet the needs of a variety of applications, such as power supplies, DC/DC converters, high-frequency switching modules, and other EMC devices. Its special EMC features include a wide operating temperature range from -40°C to 125°C, broad inductance range from 0.47 μH to 510 μH, and low ESR and high current capability. The S1812-223H also features a self-resonance frequency of up to 1300 MHz to prevent noise in high-frequency applications.

Working principle of the S1812-223H involves a magnetic field being created within an inductive circuit, inducing a current flow from one terminal of the inductor to the other. This alternating current flow within the inductor provides electrical resistance (impedance) to the circuit and limits the amount of current which can pass through the inductor. This resistance is proportional to a frequency of the alternating current, providing a useful feature for EMC applications requiring stringent signal integrity limits.

The inductor\'s geometry and core material also play an important role in how effectively it functions. In the case of the S1812-223H, its core is made of soft ferrite material which provides a more linear impedance characteristic in high frequency applications. Additionally, the winding environment plays an important role in reducing external noise, and each S1812-223H is supplied in an oil-filled polyester tape super encapsulation. This ensures that these inductors will be capable of operating in harsh environments with high levels of EMI.

The S1812-223H series of fixed inductors is a versatile and reliable EMC solution for a wide range of applications. Its wide operating temperature range, broad inductance range, and low ESR ensure that this series of inductors is suitable for a variety of applications, including power supplies, DC/DC converters, high-frequency switching modules, and other EMC devices.
