Fixed inductors are common electronic components found in most electrical and electronic applications. They are used to generate and store magnetic fields, providing inductive reactance or inductance. The 1210R-391G is a type of fixed inductor that utilizes a radial-lead form factor, thereby increasing its versatility and allowing it to be used in a wide range of applications. It is a surface mount 6.3mm tall and 6mm wide, with an inductance of 2.2mH and resistance of 2.0 ohms.

Working Principle

The basic structure of the 1210R-391G fixed inductor is similar to that of an inductor. It consists of a coil of wire wrapped around a ferrite core or other magnetic material. When current flows through the coil, a magnetic field is generated, which creates a force, known as inductive reactance. This force resists changes in the current and therefore acts as a type of impedance. The amount of inductive reactance generated by the 1210R-391G depends on several factors such as the size of the coil and the inductance of the core, as well as the amount of current flowing through the coil. Inductance is a measure of the amount of inductive reactance created by a given amount of current, while resistance is a measure of the total current flow.

Applications

The 1210R-391G fixed inductor is commonly used in power supplies, DC-DC converters and other power electronic applications. They are also used to protect sensitive electronic components from voltage and current spikes, as well as to filter out unwanted frequencies. Additionally, they are often used to isolate and reduce electromagnetic interference (EMI) from other sources. The 1210R-391G is also used in radio frequency (RF) circuits and power amplifiers, as well as audio and video applications.

The 1210R-391G fixed inductor is a versatile and important electronic component that has a wide range of applications. Its small size and easy installation makes it an ideal choice for use in many different types of electronic systems. Although inductors are relatively simple, they can provide significant benefits in terms of power conversion and protection.
