Ferrite Beads and Chips have the potential to reduce EMI (Electromagnetic Interference). In particular, the PE-0805PFB301ST is an example of a ferrite bead/chip that is used widely. In this article I will discuss the application field and the working principle behind the PE-0805PFB301ST.
The PE-0805PFB301ST is an inductor mountable ferrite bead with a maximum working frequency of 5GHz. The standard conditions of the PE-0805PFB301ST is rated at 0.5A maximum current and its impedance range is from 40 to 500 ohm. Its total size is 0805 (8.0 x 0.5mm) and the total weight is 0.013g. Further specs on the PE-0805PFB301ST can be found on most product spec sheets.
One of the main application fields for the PE-0805PFB301ST is in EMI filters. It is used to reduce EMI that is caused by current/voltage passing through cables, otherwise known as "electrical noise." As current passes through a wire, it creates an electro-magnetic field that actually radiates and can induce unwanted signals in nearby material. By using ferrite beads, they can reduce the generated EMI by providing a path for the current to flow around and not through the filter disrupting the flow of any other devices.
The working principle behind the PE-0805PFB301ST is relatively simple. Basically, the ferrite beads act like an inductor, absorbing any higher frequency signals while allowing lower frequency signals to pass through. Since the PE-0805PFB301ST can handle frequencies up to 5GHz, it is ideal for applications where there are high frequency signals that could potentially interfere with other devices. This is a common problem in areas such as medical instruments and cellular communication.
In summary, the PE-0805PFB301ST is a common type of ferrite bead or chip used in EMI filters with a maximum working frequency of 5GHz. Its main purpose is to absorb any high-frequency signals that could interfere with other devices, while allowing lower frequency signals to pass through. This effectively reduces EMI and allows for a smoother flow of current and voltage that will not disrupt other devices.
