Fixed Inductors

Fixed inductors are electronic components that store electric current and energy in magnetic fields. They are used in the design and construction of electronic equipment. One example of a fixed inductor is the SD18-470-R. This article will discuss the application field and working principle of the SD18-470-R.The application field of the SD18-470-R fixed inductor is primarily in filter circuits and power supply noise suppression. Filters are commonly used in audio and broadcasting, electronic equipment, and communications equipment. Noise suppression is essential to ensure reliable operation of circuit components. The SD18-470-R is a radial-lead, construction air core, chip inductor. It is constructed with an insulated metal coil and is designed to provide a low DC resistance.The working principle of a fixed inductor is based upon Faraday\'s Law of Induction. This law states that a changing magnetic field is capable of creating an electric current within a coil of wire. Basically, the fixed inductor works by converting electrical energy into magnetic energy, which is then stored in a magnetic field created by current flow through the inductor. When the current is switched off, the magnetic field collapses, releasing its stored energy. The SD18-470-R is designed to provide suppression against Electro Magnetic Interference (EMI). It also has high frequency characteristics and features excellent frequency characteristics for a wide range of frequencies. It is suitable for use in circuits with rated currents up to 1.6A. The SD18-470-R fixed inductor has a low self-resonance frequency, which means that it can handle high frequencies without problems. A low self-resonance frequency also prevents signal reflections that can lead to distortion or interference. Additionally, the chip inductor\'s air core construction makes it less susceptible to interference from other magnetic fields or sources of RF energy. The SD18-470-R fixed inductor is suitable for use in a variety of high frequency and low current applications, including filter circuits, power supply suppression, audio and broadcast circuits, and communications equipment. Its low self-resonance frequency, air core construction, and high frequency characteristics makes it an ideal solution for a wide range of applications.
