Ferrite beads and chips are electronic components that help reduce electromagnetic interference (EMI). FBMH2016HM251NTV is one such component used to suppress EMI in many applications. This article will discuss the application field and working principle of this specific component.

Application Field

FBMH2016HM251NTV can be used in a variety of applications. It is commonly used for the suppression of radio frequency interference (RFI) in data signal lines, such as Ethernet cables. It can also be used in high-frequency circuits, for example to reduce harmonics on the outputs of power supplies. Power amplifiers used in audio systems, as well as power adapters and computer peripherals, may also benefit from FBMH2016HM251NTV.

Working Principle

Ferrite beads work by presenting a high impedance to high-frequency currents, and a low impedance to low-frequency currents. FBMH2016HM251NTV utilizes this principle to provide EMI suppression. The bead is made up of a ferrite core, which is a material with a very high magnetic permeability, as well as an insulated wire coil.

When a high-frequency signal passes through the bead, its high magnetic permeability causes the signal to be attenuated. This is due to the high inductance of the bead, which is the result of its closely packed turns of wire. By attenuating these high-frequency signals, the bead reduces electromagnetic interference.

At low frequencies, the bead behaves as an open circuit, meaning that only a very small amount of current is allowed to pass through it. This reduces the amount of low-frequency radiation emitted from the system, as well as reducing the amount of crosstalk between components.

Conclusion

In conclusion, FBMH2016HM251NTV is a ferrite bead that is used for the suppression of electromagnetic interference. It can be used in a variety of applications, including data signal lines, high-frequency circuits, power supplies, amplifiers, adapters, and computer peripherals. It works by presenting a high impedance to high-frequency currents, and a low impedance to low-frequency currents.
