Ferrite beads and chips refer to a type of component which includes various devices that use ferrite as a core material. One important type of component in this category is the PMC0805-202, which has a variety of different applications. This article will discuss the application field and working principle of this component.

The PMC0805-202 is a surface-mounted component for electronic-circuit control and protection applications. It is typically used in circuits to reduce AC or RF interference. In addition, it is also used as an anti-noise component in communication systems. The PMC0805-202 is widely used in IGBT motor drives and LED lighting systems.

The PMC0805-202 is a bead-type ferrite core chip that has a low-resistive nature. It is composed of a ferrite core, ceramic body, two copper wires and two pins. The ferrite core has a high electrical resistivity, while the ceramic body blocks interference from the outside. The two copper wires are used to connect the PMC0805-202 to the circuit and the two pins are used to attach it to the circuit board.

The working principle of the PMC0805-202 is based on its low-resistive nature. It works by subjecting the incoming signals to electromagnetic induction. When the incoming signals enter the core of the PMC0805-202, they are subjected to a high magnetic field. This field causes the electrons to move along the surface of the core in circles. This produces eddy currents in the ferrite chip and generates an opposing magnetic field which cancels the incoming signals.

The PMC0805-202 is an important component for various circuits and communication systems. Its low-resistive nature makes it an effective anti-noise component and its ability to reduce AC or RF interference makes it ideal for use in IGBT motor drives and LED lighting systems. By understanding the application field and working principle of the PMC0805-202, engineers and technicians can better use this component in different designs.
