Fixed Inductors: SC73-330 Application Field and Working Principle Fixed inductors, also known as inductors, are essentially a type of passive electronic component that store energy in its magnetic field and acts to oppose changes in the current that flows through it. In particular, the SC73-330 designed by the Peregrine Corporation is a power inductor that is widely used in a variety of industrial and consumer electronic products such as high-end televisions and computers. This article will discuss the application field for the SC73-330, as well as its working principle.The SC73-330 is ideally suited for the applications where the power must be continuously delivered with high performance, but the power is generated from DC sources. Such applications include DC-DC converters, power factor correctors, and DC motors. The SC73-330 is also well suited for high switching frequency products, due to its low DC resistance and high saturation current capability.When power is applied to this type of inductor, it is typically designed with a toroidal core. This toroidal core concentrates the magnetic field lines inside the core itself, which helps to promote high inductance with low leakage. The higher inductance allows for less power loss during operation and high efficiency of the inductor.The working principle of fixed inductors such as the SC73-330 is based on Faraday’s law of induction. This law states that when a voltage is applied to the inductor, a magnetic field is created, which in turn induces a current in the coil. The amount of current produced is proportional to the amount of voltage applied. Furthermore, the current that is generated is also proportional to the rate of change of the applied voltage.The SC73-330 is designed to have high efficiency and low power losses due to its toroidal design, which increases the inductance while maintaining a low DC resistance. The inductor is also designed to achieve a high saturation current in order to ensure the highest power transfer efficiency. The combination of these features makes the SC73-330 an ideal choice for high power applications.In summary, fixed inductors such as the SC73-330 are widely used in a variety of applications due to its high power efficiency and low power loss. Its features such as its toroidal design that increases inductance and its high saturation current capability make it an ideal choice for high power applications. Finally, the working principle of the inductor is based on Faraday’s law of induction, which states that a voltage applied to the inductor will generate a current proportional to the amount of voltage applied and the rate of change of that voltage.
