Fixed Inductors are among the most common components used in electrical circuits and their range of applications is very wide. PT12117SL is a high heat resistant fixed inductor typically used for high frequency applications, including in power supplies, inverters, converters, LED display, and motor control devices. The PT12117SL is designed for automatically temperature compensation and with a built-in ESD diode, it becomes a great choice for use in high frequency switching mode power supplies.The PT12117SL fixed inductor is used for providing inductance in electrical circuits. This inductor is made up of an inner core, usually made of iron, whose job is to create a magnetic field. Around this core is wound a wire coil of copper, which acts as a conductor to the flow of electrical current. When an electric current is passed through the coil, a magnetic field is created in the vicinity of the iron core, which then interacts with the electrical current, producing an electromagnetic field. The effect of this field is to induce an opposite current to flow in the opposite direction to the electrical current.This effect is known as inductance, and it is important for controlling the voltage and current in the electrical circuit. When used in power supplies, the inductor will be used to raise the input voltage and reduce the output current, allowing the device to work more efficiently. In other types of circuits, the inductor is used to provide stability and address over-voltage or surge current problems.The PT12117SL fixed inductor is a special type of inductor because it is capable of withstanding higher temperatures compared to other inductors, making it suitable for use in high frequency applications. It is automatically temperature compensated, meaning that it accommodates to higher temperatures, which can extend its lifetime. Additionally, it has a built-in ESD diode, which reduces electrical noise and protects it from electrostatic shocks. This makes it great for use in a variety of high-performance circuits.The PT12117SL fixed inductor is available in a variety of sizes and ratings, so it is suitable for a wide range of applications. It is a high reliability and low cost component, and is therefore widely used in for various electronics devices. The higher temperature tolerance and ESD protection makes this inductor an ideal choice for circuit designs that require reliable and efficient performance.
