Fixed Inductors

IMC1812EB680J application field and working principle

Inductors, which also can be called coils, are one of the most common and important types of electronic components. Fixed inductors, as their name implies, are inductors that once specified do not change their value. Common fixed inductors are categorized into several different types, namely high-frequency inductors, wire-winding inductors, multi-layer chip inductors, power inductors and so on. The IMC1812EB680J is a fixed inductor in wire winding form.The application field of the IMC1812EB680J can be divided into two categories, digital and analog. In the digital field, it is widely used in switching power supplies because of its low resonance and low cost, such as laptops, mobile phones, cameras, mp3/mp4 players and some other digital products. In the analog field, it is used in the fields of communication and radio frequency, such as base station power stations, satellites, etc., because of its excellent features of high current and high frequency.The working principle of coil is based on Faraday’s electromagnetic induction law. When an alternating current passes through a coil, an electromagnetic field is generated around it. This electromagnetic field is then couples with the electric field in the coil to form an inductance. This electromagnetic induction produces a self-induced electromotive force within the coil, which is in direction opposition to the main source, thus creating a pressure difference. This pressure difference provides a damping effect on the current flow, thereby limiting or regulating the current. The size of the damping effect is proportional to the inductance.The IMC1812EB680J has a wide range of applications, and its working principle is quite important to many areas in electronics industry. Its self-induced electromotive force helps to provide a damping effect on current flow, which helps to maintain a stable electric condition in the circuit and eliminates noise. In terms of application field, it is mainly used in switching power supplies, communication, and radio frequency products, as it is much lower in cost than regular inductors.
