Fixed Inductors are electric components used for controlling electric circuits and systems. They are primarily used for regulating the flow of electricity and preventing large surges of current. The 1210-472K is one of the most common fixed inductors, used in many applications. This article will discuss the application field and working principle of the 1210-472K. The 1210-472K has an inductance range of 4.7uH to 10uH, making it suitable for a variety of applications. It has a maximum saturation current of 10A, withstanding currents up to 30A when properly cooled. It is used in switch mode power supplies (SMPS). It is also used in motor control systems, DC-DC converters, and other power supply applications. The 1210-472K is an air-core, non-polarized, cylindrical inductor. It is composed of a round copper coil wound on a plastic frame. The windings are insulated from each other and from the frame using an insulating material. The 1210-472K is very reliable and durable, and is able to withstand extreme temperatures and vibrations.The working principle of the 1210-472K is based on Faraday’s law of induction. When an electric current flows through the inductor, a magnetic field is generated within the air gap between the inductor windings. This magnetic field stores energy in the field, resulting in a voltage drop across the inductor terminals, based on Faraday’s law. This voltage drop creates a resistance to the flow of the current, causing the current to be limited to the desired value.The 1210-472K has many advantages over traditional inductors. It is very efficient and produces very low levels of EMI. It is also more compact and lighter than other types of inductors, making it easy to install and maintain. The 1210-472K also has a high ripple current and can withstand temperatures up to 125°C.The 1210-472K is a reliable and versatile inductor used in many applications. It is easy to install and maintain, and its efficiency, low levels of EMI, and high temperature rating make it a popular choice for many applications. This article has discussed the application field and working principle of the 1210-472K fixed inductor.
