Fixed Inductors

Fixed inductors are often used in many different applications, such as electronic systems, power supplies, oscillators, signal processing systems, audio systems, and motor control applications. They are capable of providing precise signal frequency, or time-varying fields, to various electronic components.

The 0819R-20K is a type of fixed inductor, and is a small-sized, low-profile device designed for high-end power applications. This device offers a high-performance solution for various types of applications, and is ideal for use in all types of AC/DC and DC/DC converters as well as switched-mode power supplies.

The 0819R-20K consists of segmented, epoxy-filled, ferrite core that is crucial to its operation. It is designed to operate or act as a single inductor instead of two electrolytic capacitors. This helps reduce the overall size of the device while providing a more stable and reliable signal.

Working Principle

The 0819R-20K operates by supplying current through the core of the ferrite material. This current generates a magnetic field which induces a voltage on the wire winding coiled around the ferrite core. The amount of voltage that is induced is related to the size of the core, the amount of coils around the core, the number of turns in the winding, and the current passing through it.

The voltage induced on the winding due to this magnetic field is then used as voltage compensation, as the current flowing through the winding increases, the induced voltage compensates it in opposition to the current, thus stabilizing the output voltage of the device.

The 0819R-20K is capable of operating from DC to 100kHz, and is suitable for applications such as DC/DC converters, AC/DC motor control and the generation of high-power circuits. It can also be used to boost the performance and reliability of high-voltage DC systems.

The 0819R-20K offers several advantages, including high power output, low cost, small size, and ease of use. Additionally, it is easily integrated into existing systems, making it a popular choice for many applications.
