Inductors are passive electrical components which consist of a conductor loop or single coil. The flow of electric current through the conductor produces an electromagnetic field that induces a voltage proportional to the rate of change of the current through the loop. Inductors are often used in electrical circuits to store energy and control circuit performance. Fixed inductors, such as the PT400-1200-VM, have been designed for specific applications and feature specific working principles.

The PT400-1200-VM fixed inductor is a high-performance part designed to meet the demands of high-current applications in air and vacuum environments. This inductor is constructed from ferrite beads with an enameled copper or aluminum wire and is characterized by low induction, low DC resistance, high current capacity, and high frequency response. Additionally, the PT400-1200-VM is designed with a high voltage-saturation current rating, making it an ideal solution for high-voltage circuits with high-current applications.

The PT400-1200-VM fixed inductor’s working principle is centered around the principle of inductance, which states that a sinusoidal current produces an alternating magnetic field and an alternating voltage in the form of an electromotive force. As the current flow through the inductor is increased, the RF interference is also increased, resulting in electromagnetic coupling. This inductive action creates the desired response of the inductor, allowing it to effectively filter out external interference.

Additionally, the PT400-1200-VM fixed inductor has been optimized to minimize flux leakage while providing high current capacity. This part utilizes a number of winding techniques to achieve the desired effect, such as a high pitch winding or stacked ferrite cores with a balanced flux saturation. These techniques have been designed to provide multiple layers of protection for high-current applications, eliminating crosstalk or interference from outside sources. Furthermore, the use of a ferrite core helps to reduce AC losses and thermal beyond practical temperature limits.

The PT400-1200-VM fixed inductor is specifically designed for use in high-current applications in air and vacuum environments. With its optimized low induction, low DC resistance, high current capacity, and high frequency response, this part offers an ideal solution for these demanding applications. Its optimized winding techniques provide multiple layers of protection, eliminating crosstalk or interference from outside sources. Furthermore, the use of a ferrite core helps to reduce AC losses and keep thermal levels below permissible limits. By understanding the working principles and applications of the PT400-1200-VM, engineers can easily determine if this is the optimal solution for their current application.
