Introduction

Fixed inductors, commonly known as choke coil or ferrite core inductors, are basic electrical components used in power electronic design and industrial automation fields. PM75-820K-RC is one of the popular fixed inductors in the market. It features very low DC resistance at the time of its high inductance and provided with a full metal shield which increased resistance to external influences such as electro-magnetic waves and shocks. The fixed inductor is used in power electronic circuits such as DC-DC switching converters and power supplies and also in the industrial fields due to its features like high power inductance and wide operating temperature range. This article will discuss the application fields and working principle of the PM75-820K-RC fixed inductor in detail.

Application Field

The PM75-820K-RC Fixed Inductor is mainly used in power electronic circuits such as DC-DC switching converters and power supplies due to its features such as low resistance and high inductance, wide operating temperature range of -40°C to 85°C) and strong resistance to external influences. It is also used in the industrial fields due to its features like high power inductance, excellent anti-interference ability and high efficiency.In the power electronic fields, the PM75-820K-RC Fixed Inductor can be used as a filter and assist in controlling the current and voltage in power supplies and DC-DC switching converters. It can also increase the system\'s efficiency by reducing the common mode noise in these converters and provide smooth current and voltage passage. It is also compatible with high-frequency switching circuits and current sensors. In the industrial fields, the PM75-820K-RC Fixed Inductor can be used as a transformer or choke coil, providing sufficient load current for industrial automation tasks. It also functions as an inductive check for detecting motor faults, enabling proper speed control and monitoring of loads in automatic weaving machines, dynamic machining centres and conveyer belts.

Working Principle

The PM75-820K-RC Fixed Inductor is based on the law of inductance, which is that when current flows through a conductor, a magnetic field is produced which induces a voltage in the same conductor. The voltage induced by the magnetic field is proportional to the rate of change of the current. This induction acts as an opposition to any changes in current and hence, the current does not change at the same rate as the applied voltage. So, the current remains constant over a period and therefore, the inductor acts as a filter for unwanted frequencies, hence providing a steady current and voltage.The PM75-820K-RC Fixed Inductor also has a wide operating temperature range of -40°C to 85°C, which makes it suitable for use in industrial applications. It also has a strong resistance to external influences such as electro-magnetic waves and shock, ensuring that correct current and voltage values are maintained in power electronic circuits. The PM75-820K-RC Fixed Inductor also functions as a transformer or choke coil, providing sufficient load current to a variety of industrial automation tasks.

Conclusion

The PM75-820K-RC Fixed Inductor is a popular fixed inductor in the market and is most commonly used in power electronic circuits and industrial applications. The fixed inductor is based on the law of inductance which helps in providing a steady current and voltage at the time of its high inductance and wide operating temperature range. It is also strong resistance to external influences due to its protective shield, making it ideal for use in harsh environments. The PM75-820K-RC Fixed Inductor is an important component in power electronic and industrial applications which ensures good performance and efficient operation of the equipment.
