Fixed Inductors: 2534R-72K Application Field and Working Principle

Fixed inductors, such as the 2534R-72K, are passive electronic components with a designed inductance in a single coil. They are widely used in many practical circuits where low noise is needed and power dissipation is an issue. This article will discuss the application field and working principle of the 2534R-72K.The 2534R-72K is a type of fixed inductor which is best suited for high frequency applications, such as for switching power supplies or for radio frequency (RF) applications. It consists of a single winding coil made from a high-quality magnetic core material such as ferrite, iron powder, or ceramic core. The design of the single winding coil determines the resistance and inductance of the component. The inductance of the 2534R-72K is rated at 72K ohms, and its AC resistance is 0.4 ohms. The maximum working current is 2 Amps, and the voltage rating is up to 100V. It is designed to be physically robust, allowing it to be mounted securely, and is suitable for operation in temperatures up to a maximum of 105°C.The working principle of the 2534R-72K is relatively straightforward. When current passes through the winding coil, it creates a magnetic field around it. This magnetic field creates an opposing voltage to the voltage applied to the coil. This opposing voltage is referred to as inductive reactance and it is a function of the frequency of the current passing through the coil.The inductive reactance increases with increasing frequency, and is inversely proportional to the current through the coil. As the frequency of the applied current increases, the opposing voltage also increases, resulting in a decrease in current. This decrease in current is known as the inductive lag. This inductive reactance is what allows the 2534R-72K to be used in high frequency applications, where low noise is needed.In summary, the 2534R-72K is a type of fixed inductor designed for high frequency applications. It has a rated inductance of 72K ohms and an AC resistance of 0.4 ohms. The working principle of the 2534R-72K relies on its inductive reactance, created when a current passes through the winding coil, which creates an opposing voltage to the applied voltage. This opposition increases with increasing frequency, resulting in a decrease in current and reducing noise.
