Fixed Inductors

Inductors are fundamental passive components used in electronics. These electronic components store energy using a magnetic field and their electrical characteristics change in relation to the frequency of the current flowing through them. The type of inductor used depends on the application and the frequency of the current being produced. One type of inductor is the Fixed Inductor, and an example of this is the HF1008R-472G inductor.

HF1008R-472G Overview

The HF1008R-472G Fixed Inductor is a surface-mount device from Huatian Tech that was created to support high-frequency operations. In terms of its operating characteristics, it has a low equivalent series resistance (ESR) which is at around 0. 160Ω; its ideal inductance range lies between 0.4Ω to 47.2μH and it has a maximum DC current rating of 8.0A.The HF1008R-472G is a simple compact device, measuring less than 1 mm in height making it ideal for small space applications. It is RoHS compliant which means that it is safe for human usage and does not contain any hazardous materical. It has an operating temperature range of -40°C to +105°C and has a peak current rating of 13.40A.

HF1008R-472G Applications

The HF1008R-472G is most useful when used in high-frequency applications. Its flexibility and small form factor allow it to be used in a variety of high-frequency applications such as in low-noise automotive components, ultra-compact high-efficiency switching power supplies, low EMINotebook computers, and portable computers. The HF1008R-472G is also ideal for radiofrequency applications as it can help reduce spurious emissions as well as reduce the power supply conducted EMI. It is also suitable for use in mobile devices such as smartphones and tablets due to its low power consumption and low EMI emission.

HF1008R-472G Working Principle

The working principle of the HF1008R-472G Fixed Inductor is based on the theory that a changing current will create a voltage in a wire through electromagnetic induction. This changing current, also known as an alternating current (AC), will create a magnetic field around the wire. This magnetic field will then interact with the core of the inductor which is usually made of a material such as iron. The HF1008R-472G is also designed to limit the amount of AC current flowing through it, allowing the signal to pass through without distortion. This is critical for high frequency applications where distortion can cause signal loss and degrade the quality of the output.

Conclusion

The HF1008R-472G Fixed Inductor is a compact, versatile device that is designed for use in high-frequency applications. Its small size and low ESR make it ideal for use in many different electronic components such as in low-noise automotive components, ultra-compact high-efficiency switching power supplies, and low EMINotebook computers. The HF1008R-472G also has a low equivalent series resistance, a wide range of inductance values, and a peak current rating of 13.40A. Finally, its working principle is based on electromagnetic induction which helps limit the amount of AC current flowing through it without causing distortion.
