Ferrite Beads and Chips

Ferrite beads and chips are indispensable components for most electronic circuits. Not only do they help reduce electromagnetic interference (EMI) in an electronic system, but they can also serve as a protection against short circuits or significant voltage fluctuations. PE-1206PFB500ST, as one of the most commonly used ferrite bead components, is used to provide impedance control for high-frequency applications. This article will discuss the application fields of PE-1206PFB500ST and its working principle in detail.

Application Field of PE-1206PFB500ST

PE-1206PFB500ST is a type of low cost, high frequency ferrite chip bead with an operating temperature range of -55℃ to +125℃. It is designed for non-critical applications and is available in various forms such as a through hole, a surface mount device (SMD), or a vertical mount device (VMD). As a low-cost, high frequency part, it is ideal for applications such as power supplies, audio, and video devices, LCDs, mobile handsets, computer displays, or any other circuits that require impedance control.

This type of chip bead is also suitable for applications where the temperature range is not critical. It can be used in relatively low cost printed circuit boards, where it can be easily installed with no additional components. Furthermore, due to its simple construction, it offers excellent cost-to-performance ratio compared to other ferrite components.

Working Principle of PE-1206PFB500ST

The working principle of PE-1206PFB500ST varies depending on the application. Generally, this chip bead helps to provide impedance control by limiting the amount of current that can pass through the circuit. It does this by utilizing a ferromagnetic material, which works by changing its resistance at different frequencies. This, in turn, enables it to filter out any unwanted noise or interference, ensuring that the signal passing through the circuit is free from any type of electromagnetic interference (EMI).

The impedance of the chip bead also changes with the frequency. This is due to the way that the ferrite material absorbs the energy from the incoming signal, thus leading to a reduction in the amplitude of the signal. This helps to reduce any distortion that might occur in the signal, and can also act as a protection against transient voltage spikes.

The impedance of the chip bead also changes with temperature. This is due to the way that the ferrite material absorbs heat, leading to a change in its resistance. Thus, the chip bead helps to provide protection from temperature extremes, as well as any short circuit events that might occur in the circuit.

Conclusion

In conclusion, PE-1206PFB500ST is a type of low cost, high frequency ferrite chip bead that is used to provide impedance control for high-frequency applications. It is suitable for non-critical applications due to its simple design and operational temperature range. In addition, it works by utilizing a ferromagnetic material, which helps to reduce electromagnetic interference (EMI), protect against transient voltage spikes, and filter out unwanted noise.
