CHIP FERRITE BEADS

1.0 Ferrite Beads

2.0 Parts Number Legend

It is known as absorptive beads, is more lossy and make good power filter networks because they are designed

to absorb high-frequency noise currents and dissipate it as heat. These beads have high impedance over wide high-

frequency bands, making them ideal as low-pass noise filters.
