Fixed Inductors are widely used in many applications including power supply, switched mode power supply, high speed, filter, and high current applications. The PT400R-1200 is a fixed inductor that is used in many of these applications. This product is ideally suited for use in both DC and AC circuits and provides excellent current handling capabilities. In this article, we will take a look at the application field and working principle of the PT400R-1200.

Application Field of the PT400R-1200

The PT400R-1200 can be used in a variety of applications, especially ones where compact, high power requirements are necessary. It is used in power supply applications where it can handle high current, as well as in high speed filter applications when stable performance is needed. This product also works well in motor control, high speed rail, and LED lighting applications. Additionally, the PT400R-1200 is also suitable for applications in switches, converters, and inverters.

Working Principle of the PT400R-1200

The PT400R-1200 is a fixed inductor that is constructed with a ferrite core and copper wire. When a current passes through the copper wire, a magnetic field is generated around the inductor. This magnetic field produces an EMF (Electromagnetic Force) which then induces a current in the surrounding wire. This current counteracts the current that is flowing through the inductor, resulting in the voltage across the inductor to drop. This drop in voltage is known as the inductor\'s inductance.

As the current passing through the inductor increases, the inductance also increases. This increase in inductance reduces the rate of change in the voltage across the inductor. This means that the inductor is able to store energy as the current passes through it, making it suitable for applications that require a high level of both current and voltage stabilization.

Conclusion

The PT400R-1200 is an excellent product for applications in power supplies, motor control, and high speed filtering. It is constructed with a ferrite core and copper wire, which when current passes through creates a magnetic field that induces an EMF to counteract the current. This results in a voltage drop and an increase in inductance, which can help stabilize both current and voltage. As such, the PT400R-1200 is a reliable fixed inductor to use for many applications.
