Fixed inductors are used in a variety of electrical applications and come in different shapes and sizes. The PT12137SL is a type of fixed inductor designed for use with a wide range of circuits, depending on the application. This article outlines the PT12137SL’s application field and working principle.One of the most common applications of fixed inductors is in power supply designs. The PT12137SL is a surface-mount inductor designed specifically for these applications. This type of inductor has a high self-resistance, meaning that it is capable of drawing a relatively large amount of current with minimal losses. The inductor also features low insertion losses, meaning that it can transfer power over long distances with minimal energy loss.The PT12137SL also has applications in audio and telecommunication systems. Its wide frequency range and linear construction make this type of inductor an excellent choice for low-frequency audio applications, due to its ability to produce consistent audio signal output over long distances. Additionally, the PT12137SL’s low self-resistance and low insertion losses makes it an ideal choice for use in telecommunication systems, where it can transmit signals over long distances with minimal losses.The PT12137SL’s working principle is based on the principle of inductance. All inductors consist of a coil of wire and a core. When an electrical current is passed through the coil, a magnetic field is generated around the coil. This magnetic field induces a current in the core, which in turn creates an opposing magnetic field. When the magnetic fields from the core and the coil overlap each other, they create a repelling force, which forces the current to pass through the coil.The PT12137SL is a specific type of fixed inductor known as a polymer-based inductor. This type of inductor uses a special polymer material to increase the efficiency of the inductance process. The polymer material increases both the amount of current the inductor can draw and the amount of power it can transfer over long distances. It also reduces the amount of energy lost due to induction.In summary, the PT12137SL is a type of fixed inductor used in electrical applications such as power supplies, audio systems, and telecommunication systems. Its working principle is based on the principle of inductance and utilizes a special polymer material to increase efficiency. The PT12137SL offers good performance in terms of current handling, power transfer, and energy losses.
