Fixed Inductors : SRP7030-3R3M Application Field and Working PrincipleFixed Inductors are devices that store magnet energy in a coil which is then released back into a circuit. They are used to control and shape currents in the form of a sinusoidal waveform in order to enable efficient power transformation. They are also used in power electronic applications to control voltage and current levels.The SRP7030-3R3M belongs to the SRP series of Fixed Inductors produced by Sony. It is a non-polar, three-pin device that consists of a self-supporting coil of enameled copper wire, encapsulated in a plastic housing. The parts are examined for electrical and visual defects and are subjected to stringent quality control measures. The parts are also tested for safety and electromagnetic interference (EMI) characteristics.The SRP7030-3R3M is designed to provide outstanding power transfer efficiency and EMI suppression in low frequency power supplies, solenoid valve, and motor circuits. The inductance of the device is fixed at 3.3mH +-20%. It has a saturation current of more than 7A and self-resonant frequency of 19MHz. It also features a high Q-factor of over 63 at 1kHz.The modern Fixed Inductor technology used in the SRP7030-3R3M is a combination of several factors. The high power transfer efficiency is achieved by its high inductance-to-volume ratio and its self-shielding construction. The device incorporates core loss reduction technology which minimizes energy dissipation losses. The EMI suppression is due to its self-shielding construction which reduces electrical noise emissions. The high Q-factor enables a higher degree of power transfer efficiency and EMI suppression.The application field of the SRP7030-3R3M includes automotive and industrial applications, low frequency power supplies, AC/DC converters and solenoid valve, and motor circuits. It is suitable for use in a wide range of temperature and humidity environments in order to meet the application requirements.The working principle of a Fixed Inductor is based on its distinct shape which involves a set of windings and a core, as well as a coil and a number of conductive layers. When an AC or DC electrical signal is applied to the device, it creates a magnetic field which induces current flow in the windings. This current flow is then converted into a voltage signal and stored in the magnetic core. When the AC or DC signal is removed, the stored energy is released back into the circuit. Depending on the design of the inductor, the magnetic field dissipates at a greater or lesser degree, thereby controlling the amount of energy that can be stored in the core.The SRP7030-3R3M Fixed Inductor provides high power transfer efficiency and EMI suppression in low frequency power supplies, solenoid valve, and motor circuits. Its advanced design and construction enable superior performance compared to traditional Fixed Inductors. Its small size and compact design make it an ideal solution for a variety of applications requiring a high degree of reliability.
