BDW type choke

Beads on Wire of impedance of Z=10Ω at 1MHz frequency,
to Z=175Ω at 300MHz frequency.
Beads on wire are used to suppress or reduce a high frequency noise in electronic circuits, by utilitizing the characteristics of increasing the impedance in high frequency. Beads on wire are often called ferrite bead cores, ferrite EMI filters.
