Eric Bogatin explains the impact of ferrite beads on power distribution networks and demonstrates when they can cause unwanted voltage spikes.
When a ferrite bead should not be used in power rail and when it is ok. Thank you Eric.

The problem
Power distribution network
What is inductance and why it is a problem
What is ferrite bead
The problem for what we need beads
Solution: LDO
Solution: Filter (ferrite bead)
: Inductor in power rail: Yes or No?
Practical example: Setup
Measurement: No filter
Measurement: Ferrite bead only
Measurement: Ferrite bead + capacitor
