Fixed Inductors are used to store energy in the form of magnetic fields. These inductors can be used in a variety of applications, such as for radio frequency (RF) filters, power circuits, motor control, amplifiers and oscillator circuits. The inductors are typically constructed by winding a coil of wire on a core. Popular core materials are ferrite magnets, powdered iron cores, and ceramic cores.The 1331-274J fixed inductor is designed to be used in an 8-pin SOIC (“small outline integrated circuit”) package and performs the same function as other inductors on the market. It is rated at 1.2 µH (1.2 microhenry) and is designed for use in switched-mode power supplies’ voltage regulator circuits.The working principle of a fixed inductor is based on Faraday’s Law of Electromagnetic Induction. When a conductor is moved in a magnetic field, an electromotive force (EMF) is induced in the coil. This is explained by the fact that a changing magnetic field induces a current in the coil, which produces a magnetic field that opposes the original magnetic field. This phenomenon is known as mutual inductance and it is used to generate voltage or current in an inductor.There are two types of fixed inductors that are found in electronic circuits, wound inductors and air core inductors. Wound inductors are made up of a coil of insulated wire wrapped around an iron or magnetic core. The core material creates a magnetic field in the center of the coil, which increases the inductance of the circuit and provides most of the storing energy. Air core inductors do not contain a core material, they only consist of a coil of wire. They still have some mutual inductance, but their inductance is much lower than that of wound inductors and as such, they are used mainly for applications where a low amount of energy storage is desired, such as RF filters.The 1331-274J fixed inductor is a wound type inductor and the core material is a ferrite. The ferrite core increases the inductance of the circuit, allowing it to store more energy. In addition, as the frequency of the switching circuit increases, the inductance of the 1331-274J also increases, allowing it to handle higher frequencies with less losses. The 1331-274J also has a low DC resistance, which improves the efficiency of the circuit. The 1331-274J is ideally suited for high frequency switched-mode power supplies, such as those used in consumer electronics like televisions, personal computers, and mobile phones. It is also suitable for other applications such as LED lighting and power control circuits.Although the 1331-274J fixed inductor has been designed for use with 8-pin SOIC packages, it can also be used with other packaging types such as THT (through-hole technology) and SMD (surface mount devices). In addition, due to its small size, it is suitable for use in compact applications, where other inductors would be too large to fit.In conclusion, the 1331-274J fixed inductor is a versatile and reliable inductor that can be used in a variety of applications. Its small size, low DC resistance, and high inductance make it an excellent choice for high frequency switched-mode power supplies, LED lighting, and power control circuits.
