Fixed inductors, also known as coils, chokes, and reactors, are passive two-terminal electrical components, used to store energy in magnetic fields. The PT1000R-1400-VM is a type of fixed inductor. This article will discuss the application field and working principle of the PT1000R-1400-VM.

The PT1000R-1400-VM is typically used in high-power switching supplies, particularly those used to power fluorescent lamps and LEDs. Its primary function is to reduce the voltage spikes caused by switching. It is also used in metal halide ballast, to reduce the high-frequency noise emitted by those systems.

The PT1000R-1400-VM is composed of a ferrite core, an iron core, and a bifilar windings. The ferrite core has a high coercivity and provides an improved shielding effect, while the iron core maximizes the magnetic flux. The bifilar windings provide a low resistance path for the current, allowing the inductor to be used in high-power applications.

The PT1000R-1400-VM works by storing magnetic energy. When electric current passes through the windings, it creates a magnetic field in the core. This magnetic field stores energy, which is released when the electric current is removed. This stored energy is then used to reduce voltage spikes, and other high-frequency noise.

In conclusion, the PT1000R-1400-VM is a type of fixed inductor, primarily used in high-power switching supplies. It is composed of a ferrite core, iron core, and bifilar windings, and works by storing magnetic energy. This energy is used to reduce voltage spikes, and suppress high-frequency noise.
