Fixed inductors are components that are based on the principle of mutual inductance for signal or power applications. They have many uses in a variety of applications. In electrical and electronic engineering, inductors are used to store energy, reduce EMI, filter signals, regulate power supply levels, and perform signal coupling.The 103-820JS is a medium-power, high-current inductor designed for use in space-constrained application. It is designed to efficiently store and manage direct current at high switching rates, making it particularly suited for DC-DC converters, battery charging applications, or LED lighting.The 103-820JS has a core material of ferrite and features a composite wound construction. This construction makes it resistant to temperature changes. It also has an outer encapsulation of flame retardant material for protection. With its low DC resistance, high saturation current rating, and low AC resistance, the 103-820JS is designed to deliver maximum efficiency and reliability. The efficient construction makes it well-suited for higher-frequency, AC or DC-DC switching circuits.The 103-820JS also features a low-E resistance, which reduces power dissipation. This property makes it suitable for applications with high efficiency ratings and low temperatures. Its low profile design and high-temperature operation make it ideal for applications with tight physical constraints.Additionally, the 103-820JS has a high inductance and low DCR ratio, making it more efficient than other inductors.In terms of working principle, an inductor works by storing and managing energy in the form of a magnetic field. The main functionality of an inductor is to convert alternating currents into direct currents, and vice versa. An AC current applied to the inductor causes the formation of a magnetic field in the core that stores energy. This stored energy is released when the AC current is removed, and a DC current is generated in its place. Similarly, a DC current applied to the inductor produces energy stored in the magnetic field that is released as an AC current when the DC current is removed.The working frequency range of an inductor depends on its design. For the 103-820JS, it is designed to work within a frequency range of 10kHz to 1GHz. High-frequency inductors, such as the 103-820JS, allow for higher switching rates, making them well-suited for DC-DC converters or power supplies for LED lighting.In summary, an inductor is a component designed to store and manage energy, and the 103-820JS is a high-performance medium-power inductor designed for space-constrained applications. It features high-current capabilities, low DC resistance, and a high inductance-to-DCR ratio, making it an efficient and reliable component for applications where circuit space is limited. Additionally, its low-E resistance and flame-retardant outer encapsulation make it a suitable component for applications with high efficiency ratings and low temperatures.
