Ferrite Beads

Ferrite Beads also known as ferrite chokes are passive devices and they are used to constrict high-frequency signals in electronic components. The ferrite becomes resistive over its intended frequency range and uses up the noise energy in the form of heat.

How do the ferrite beads work?

The ferrite bead is connected in series with the power supply rail and is often combined with t...
