Introduction to Ferrite Beads and Chips

Ferrite beads and chips are a type of passive electronic components that can be used to filter out high frequency noise on power and signal lines. It utilizes a principle called impedance matching to block high frequency noise while passing the desired signal “noiselessly”. Ferrite beads and chips are widely used in any field where high frequency noise needs to be blocked, such as in power supplies, signal lines, data transmission, and computers.

What are Ferrite Beads and Chips?

A ferrite bead is a passive component that is composed of magnetizable ferrite material with a high impedance to high frequency noise. It works by acting like a transformer, converting alternating current to direct current. When an alternating signal (high frequency noise) is applied to the input side of the ferrite bead, the signal is “trapped” inside the bead and prevented from passing through to the output side. The trapped high frequency signal is dissipated as heat.A ferrite chip is a specific type of ferrite bead that is used in the same way but is typically smaller in size. It works in the same way as a ferrite bead but is designed to be more compact and suitable for use in a circuit board.

2773044446 Application Field and Working Principle

Ferrite beads and chips are mostly used to filter out high frequency noise in power and signal lines. This type of noise is often referred to as EMI (electromagnetic interference). Ferrite beads and chips can be used to eliminate this noise, by acting as an impedance matching device.Impedance Matching is a process where a device is used to match the impedance of two circuits. In the case of a ferrite bead, the beads impedance is much higher than the impedance of the noise it is trying to block. This causes the waveform of the noise to be altered as it passes through the bead, effectively blocking the noise.This same impedance matching principle is also used in data line applications, such as cables connecting modems and printers to computers. In these applications, ferrite beads can be used to reduce cross talk between signals and data.A ferrite chip can also be used to reduce RFI (Radio Frequency Interference) emitted from a circuit. In this case, the ferrite chip works as a filter to the radio frequency waves which can interfere with other electronic circuits.

Conclusion

Ferrite beads and chips are a type of passive electronic components used to block high frequency noise. They work by utilizing an impedance matching principle, where the beads impedance is much higher than the impedance of the noise it is trying to block. Ferrite beads and chips can be used to filter out high frequency noise in power and signal lines, reduce cross talk between signals, and reduce RFI emitted from a circuit.
