Fixed inductors are electronic components used to store energy in the form of an electric field. They are used in a variety of applications, with the SRP4020FA-R47M being a popular choice for many. This article will provide an overview of the application field and working principle of the SRP4020FA-R47M.The SRP4020FA-R47M is a surface mount fixed inductor with an inductance of 47 milli-henrys. It is a high-temperature, high-Q, low-DCR inductor that operates in temperatures up to 250°C. It is suitable for a wide range of applications, such as high-density power supply designs, high-frequency noise filters, and line matching circuits. The SRP4020FA-R47M is designed to handle large electrical pulses and current spikes while still retaining stable inductance levels. Its inductance characteristics remain incredibly stable throughout its operating temperature range. This makes it an excellent choice for applications where inductance stability is a primary concern. The SRP4020FA-R47M’s working principle is quite simple. It consists of two main components: an inductor and a capacitor. When the inductor is connected to a power source, a magnetic field is generated, which stores energy. This stored energy is then released as a current when a load is connected to the inductor. This current is regulated by the capacitor, which filters out any unwanted signals and holds the current to a constant level. As far as operation is concerned, the SRP4020FA-R47M is quite simple. It can be used in a variety of configurations, including single and multiple coils, as well as AC and DC applications. When operating in a DC application, the inductor should be connected to a resistor to dissipate the current when the inductor is disconnected from the power supply. In summary, the SRP4020FA-R47M is a high-temperature, high-Q, low-DCR surface mount fixed inductor with an inductance of 47 milli-henrys. It is suitable for a wide range of applications, such as high-frequency noise filters, line matching circuits, and more. Its simple two-component design and stable inductance characteristics make it an excellent choice for applications where inductance stability is a primary concern.
