Fixed inductors, or sometimes referred to as edge wound coils, are an essential type of inductor that are used in a broad range of applications. Among the most common types of fixed inductors are the 1210R-390J, which is an inductor that offers both high performance and a low profile. This article will discuss the application field and working principle of the 1210R-390J fixed inductor.

The 1210R-390J is a fixed inductor designed primarily for power systems, such as power supplies, power converters, dc-dc converters, and motor drives. It is also suitable for use in many other applications, such as radio frequency (RF) circuits, audio amplification, and instrumentation. The 1210R-390J fixed inductor is especially well-suited for power supplies because it is capable of providing a high-current output without consuming a large amount of board space. This is due to its unique design, which combines a conductive winding with an impregnated ferrite core material.

The 1210R-390J fixed inductor is composed of two main components. The first is a conductive winding, which is composed of high-purity copper wire wound on an aluminum base core. This creates an inductive loop, through which electrical current flows. The second component is a ferrite core material, which is impregnated with a high-grade epoxy resin. This material is designed to help increase the inductance of the inductor and reduce losses due to eddy current heating.

The 1210R-390J has a rated current of up to 2.5A, and a room temperature inductance of 390mH. It also has a temperature coefficient of 1.5%/°C. The inductor is designed to be used in an ambient temperature range of -40°C to +85°C. Additionally, the 1210R-390J has a maximum rated DC resistance of 0.05Ω, making it suitable for use in high-current applications.

The working principle of the 1210R-390J is based on the concept of Faraday’s law of induction. When a current is passed through the conductive winding, it produces a magnetic field. The magnetic field interacts with the ferrite core material, which in turn produces an opposing field. This creates a feedback loop, which induces a voltage in the coil and increases the inductance. This is how the 1210R-390J produces an inductive output.

The 1210R-390J fixed inductor is an ideal choice for many applications, due to its high-current output, low profile design, and temperature performance. It is capable of providing inductive output in a variety of environments, and its reliability makes it a great choice for power supplies, converters, dc-dc converters, RF circuits, and audio amplification applications.
