Ferrite Beads and Chips

The PMH0805-800, a type of ferrite bead, has many application fields and a distinct working principle. A ferrite bead is an inductive component that is used to suppress high frequency electrical noise in electronic circuits. The PMH0805-800 is a high frequency wide band ferrite beads with impedance 40ohm – 1000ohm.

Application Fields and Benefits:

Some of the application fields of the PMH0805-800 include:

• Telecommunication equipment
• High-speed digital signal processing
• Computer peripheral controllers
• Remote control systems
• Power conversion circuits
• Automotive electronics

The PMH0805-800 ferrite bead is beneficial because it attenuates high frequency by a maximum of 800 MHz (which includes operation in the 100 MHz - 800 MHz range). This means that its transmission-line-iterrupting technology, which breaks up potentially harmful high-frequency interference, is more effective than other types of ferrite beads. In addition, the PMH0805-800 provides low mutual inductance and high self-resonance to allow for a high signal-attenuation level across the entire frequency range.

Working Principle

The PMH0805-800’s working principle is based on high-frequency inductive absorption technology. This type of technology is used to break up high-frequency interference using an alternating current (AC) without using an electrical filter.

Simply put, the ferrite bead works by causing high-frequency current to flow through the material that composes the bead. This results in conversion of the high-frequency energy into heat energy, which is then dispersed in the surrounding environment. This interruption of current flow effectively eliminates potentially harmful interference which could otherwise cause damage to a given device.

The PMH0805-800 ferrite bead also provides a high level of self-resonance, ensuring that magnetic interference is minimized or eliminated. By disrupting the magnetic fields that can be generated inside a device, this type of ferrite bead helps lower the risk of impact on sensitive electronic components.

Conclusion

The PMH0805-800 is a ferrite bead with many application fields and a distinct working principle. Its inductive absorption technology is beneficial for suppressing high frequency electrical noise in electronic circuits. It can also reduce the risks of magnetic interference, ensuring that sensitive electronic components are protected from potentially hazardous interference.
