Introduction
Fixed inductors, also known as fixed chokes or fixed reactive components, are inductive devices that allow a steady current flow in one direction, but opposition to current flows in the opposite direction. One such device is the 0819R-68G series of fixed inductors.Application Fields
The 0819R-68G series of fixed inductors are specifically designed as DC power line filters, which are widely used in AC and DC input protection circuits for electrical equipment. The inductors also have a wide range of other applications. Examples include switching power supply filters, interference suppression circuits, and telecommunication line filters.Features
The 0819R-68G series of fixed inductors features a wide variety of options. The inductors are available in a variety of sizes and inductances with high stability and high rated currents ranging from 0.1A to 10.0A. The inductors also have temperature stabilities of +-50 to +-200ppm from -40°C to +85°C, and have an operating frequency range from 0Hz to 20MHz.Working Principle
Fixed inductors work on the principle of mutual inductance. The core material of the inductors is a soft magnetic material, typically a ferrite core, which allows varying magnetic fields to be created in the inductor’s winding. When an alternating current is passed through an inductor, an alternating magnetic field is created around the inductor, as well as an alternating flux in the core. When the alternating current passes through the winding, the magnetic forces oppose each other, resulting in an opposing force, or self-inductance. This opposed force slows down the current flow, and generates a voltage that is proportional to the rate of current flow.Advantages and Disadvantages
Fixed inductors are widely used in many electrical and electronic applications due to their low cost, simple construction and relatively low losses. They also have very low temperature drifts, ensuring a consistent performance over a wide temperature range. However, they exhibit a poor frequency response, meaning that their inductance characteristics change with frequency. This can have undesirable effects in applications where frequency-dependent response is required.Conclusion
The 0819R-68G series of fixed inductors are widely used in a variety of applications. Their low cost, simple construction, and relatively low losses make them ideal for DC power line filters, switching power supply filters, interference suppression circuits, and telecommunication line filters. These fixed inductors are designed to provide reliable performance over a wide temperature range, but their poor frequency response may be undesirable in applications requiring frequency-dependent characteristics.The specific data is subject to PDF, and the above content is for reference
