Introduction

Fixed Inductors are components widely used in environmental protection, high-voltage magnetic induction and other fields to store energy. The 1638R-00H Fixed Inductor is a high-performance, high-frequency, low-noise fixed inductor designed specifically for two-port circuits. It is characterized by a high self-resonance frequency which is usually above 1 MHz, a small size, low RMS current and a wide operating temperature range.

Applications

The 1638R-00H Fixed Inductor has a wide range of applications in various fields. It can be used as part of a filter in a DC-to-DC converter and as an inductor in a piezoelectric speaker. This component is also suitable for applications such as beamforming antennas, tuned antennas, RFID tags, RFID readers, and wireless power devices. In addition, the 1638R-00H Fixed Inductor can be used in a variety of applications pertaining to environmental protection, such as particle filters, air filters, and air purifiers.

Construction and Operation

The core of the 1638R-00H Fixed Inductor consists of a ferrite core with a tin-plated and gold-plated copper conductor which is wound around this core in a spiral pattern. The inductor is enclosed in an epoxy shell and hermetically sealed to help prevent dust and other environmental contaminants from accessing the inductor\'s internal components.The operation of the 1638R-00H Fixed Inductor is based on Faraday\'s Law of Induction, which states that the magnitude of the induced electromotive force in a closed circuit is proportional to the rate of change of the magnetic flux in the circuit. In other words, when an electric current flows through the inductor, it will generate a magnetic field which induces a voltage in the inductor\'s windings. This induced voltage is the self-resonance frequency of the inductor.

Conclusion

The 1638R-00H Fixed Inductor is a versatile and reliable component which is widely used in various fields such as environmental protection, high-voltage magnetic induction, and other fields. It has a high self-resonance frequency which is usually above 1 MHz, a small size, low RMS current, and a wide operating temperature range. Its operation is based on Faraday\'s Law of Induction, making it an efficient and effective component for a variety of applications.
