Introduction of Fixed Inductors

Fixed inductors are electronic components that use the principle of electromagnetic induction to convert electrical energy into stored magnetic energy. They are widely used in electronics, particularly in power supplies and other types of electrical circuits, and can be found in many everyday products. Fixed inductors are typically constructed from ferromagnetic materials, such as iron or steel.The primary function of a fixed inductor is to store energy in its magnetic field and then release it when there is a change in the inductor’s current. This stored energy is available if needed and can provide a powerful source of energy. Fixed inductors are also commonly used to filter out interfering signals and to generate higher frequencies than can be harmonically generated.

SRP1238A-2R2M Application Field and Working Principle

The SRP1238A-2R2M fixed inductor is a device that is designed to store a certain amount of energy and release it when there is a change in its current. The SRP1238A-2R2M is most often used in applications such as dc-dc converters, audio amplifiers, and low power digital systems. Its high quality construction and features make it ideal for such applications.The SRP1238A-2R2M has a rated inductance of 2.2μH (Micro Henries) with a tolerance of 20%. This inductance is ideal for circuits that require a slight increase of current when a change in voltage occurs. It also has a dc resistance of 0.04Ω (Ohms), which ensures low power losses and minimal heat generation.The working principle of the SRP1238A-2R2M fixed inductor is based on the Faraday-Lenz law. This law states that the induction of electrical energy (voltage) in a circuit occurs whenever a rate of change of magnetic flux is present. The SRP1238A-2R2M uses this law by using a core of ferromagnetic material. The material stores energy in the form of a magnetic field, and then releases it when a change in current is detected.The SRP1238A-2R2M is well suited for applications such as dc-dc converters, audio amplifiers, and low power digital systems. Its high quality design and features make it reliable and cost-effective. By using the Faraday-Lenz law, the SRP1238A-2R2M fixed inductor provides a reliable source of energy in a wide range of applications.
