Introduction

Fixed inductors, or simply inductors, are passive components with the main function of storing energy in its magnetic field. This typically occurs in alternating current (AC) circuits, where inductors are used to delay current, smooth voltage, prevent voltage spikes or protect from overcurrent. Inductors come in a large variety of sizes and shapes, and one of them is the 0819R-60H.

0819R-60H

The 0819R-60H inductor is characterized by their high inductance. The 0819R-60H inductor is a fixed inductor featuring an epoxy-molded bobbin body package that reduces to a height of 8.2mm. The 0819R-60H inductor is great for high-current applications as they provide a high current tolerance. They also have a high saturation current, so they can withstand extended periods of peak currents. In addition, the 0819R-60H inductor features low stray magnetic flux, protecting internal parts or components from interference. The inductor also boasts a wide operating temperature range, allowing it to endure high thermal loading in environments where operating temperatures may be constantly changing.

Application Field of 0819R-60H

The 0819R-60H is a popular choice for applications where a high current rating is required, such as in switch mode power supplies, automotive electronics, audio system amplifiers, motor drives, and renewable energy systems. The lower profile and smaller package size of the 0819R-60H make it well-suited for tight space applications such as mobile phones.

Working Principle of 0819R-60H

The working principle of the 0819R-60H inductor is based on Faraday’s Law of Induction. The law states that the voltage across an inductor is directly proportional to the rate of change of current. That is, when current changes, voltage is induced across the inductor. This is known as inductive reactance and behaves similar to electrical resistance, dissipating energy as it opposes the change of current. This in turn creates a magnetic flux field in the inductor which stores energy. When AC current is applied to an inductor, the magnetic field around the inductor grows and collapses, inducing an alternating EMF in the inductor and creating an opposing voltage to that of the applied current. This opposing voltage is known as the back EMF, and is the basis of inductor’s current limiting effect. The diffusion of energy over a period of time causes current delivery to be smoother and with less current spikes; thus, inductors reduce the risk of system component damage due to overcurrents.

Conclusion

The 0819R-60H inductor is an excellent choice for applications requiring a high current rating. Its epoxy-molded bobbin body package enables it to withstand even high thermal loading environments, while its low profile and small package size makes it suitable for tight spaces. The inductor works based on Faraday’s Law of Induction, providing protection against current spikes and voltage fluctuations. Therefore, the 0819R-60H inductor can be considered a reliable and reliable solution for these dense current applications.
