Fixed Inductors

SP1812-823G application field and working principle

Fixed inductors are common components that store energy in the form of magnetic fields. They are frequently used in power supplies, filters, DC/DC converters, latching circuits and other electronic circuits. The SP1812-823G is a surface mount fixed inductor that is commonly used for power supplies and DC/DC converters. The SP1812-823G is a low inductance, low profile fixed inductor that can be used in a wide variety of applications. It exhibits high reliability, low profile, low DC resistance and stable inductance over the operating temperature range. The product measures 12.8x8.3mm and has a package thickness of 1.6mm. As a type of SMD inductor, it is made with high quality material and is lead-free RoHS compliant.The SP1812-823G is designed to provide a high integration solution for energy storage and filtering applications. It can withstand higher temperatures and still offer stable performance. The working features of the SP1812-823G are rated with an inductance value of 8.2uH, a rated current of 2.2A, and a tolerance of ±10%. The SP1812-823G is designed for a wide variety of applications including signal filtering, active Bias, decoupling, power management and power switching. The working principle of the SP1812-823G is simple. It produces a magnetic field when DC current flows through it. The size of the magnetic field produced depends on the current flowing through the inductor. The magnetic field then induces a voltage across the inductor, which is proportional to the rate of change of current flow through the inductor. This voltage opposes the rate of change of current, which results in a steady current flow in the circuit, unless the inductor is shorted.The SP1812-823G can also be used to filter radio frequency (RF) signals. It exhibits excellent suppression of electromagnetic interference (EMI) and radio frequency interference (RFI). It also offers excellent immunity against static electricity and can be used to protect sensitive electronic components from EMI.In conclusion, the SP1812-823G is a low profile, high quality fixed inductor that is suitable for a wide range of applications. It is capable of handling high currents, can function well in high temperatures and offers excellent electromagnetic interference suppression capabilities. Therefore, it has an extensive range of uses and makes an ideal choice for a variety of electronic and power supply applications.
