Fixed Inductors - 0819-90K Application Field and Working Principle

Fixed inductors, also known as chokes, coils, or reactors, are electrical components consisting of an inductive coil wound around a magnetic core, usually made of iron. They are used in AC circuits to limit current or smooth the power supply, regulate voltage, block direct current (DC) and isolate circuits from one another. One example of an inductor is the 0819-90K model, a radial-design inductor which provides a high current capacity and low DC resistance.

Applications

The 0819-90K inductor is primarily used to suppress line interference in SMPS or other DC/DC converters. Because of its strong inductive reactance and large current capacity, the 0819-90K can suppress conducted and radiated noise in a variety of applications. These applications include computer power supplies, white-goods inverters, telecommunication, industrial control systems, and automotive electronic systems. Additionally, the 0819-90K can be used in pulse and short-term power supply and as an input filter.

Working Principle

The electrical current in an inductor is proportional to the rate of change of its magnetic flux, as described by Faraday’s law of induction. As alternating current (AC) is applied to the inductor, the magnetic flux within the wound coil produces a voltage which opposes the current, creating an inductive reactance. In a DC/DC converter, the 0819-90K inductor works by limiting the current travelling through the switching transistors. By limiting the amount of current passing through the transistors, the inductor ensures that the system operates without distortion or excessive stress, ensuring a stable output voltage and efficient operation. The inductive reactance also suppresses interference travelling through the circuit, reducing disturbing signals from other electronic components. Moreover, the design of the 0819-90K helps distribute the power evenly amongst the windings to reduce excessive heat generated during operation.

Conclusion

The 0819-90K inductor is a radial-design component designed to suppress line interference in SMPS or other DC/DC converters. It is primarily used in power supplies, white-goods inverters, telecommunication, industrial control systems, and automotive electronic systems due to its high current capacity and low DC resistance. When AC is applied to the inductor, the magnetic flux within the wound coil produces a voltage which opposes the current, creating an inductive reactance. This inductive reactance both limits the current travelling through the switching transistors and suppresses interference travelling through the circuit, making the component an ideal choice for many applications. By combining efficient operation with the right design characteristics, the 0819-90K is a reliable and efficient choice for inductive-based applications.
