ferrite bead, choke and inductor


The ferrite bead and choke are components that have inductance. This means that they have higher impedance at higher frequencies and this is why they are used. What is not clear is, why we have different terms ferrite bead and choke when we should just call them inductor.

I have searched youtube but not found any video on topic of ferrite bead and chokes and the different ways to use them and the different packages and shapes they come in and, what is the difference between them and inductor. It would be great if Dave made a video on this topic.

For reference:


its more like a resistor and a inductor

Kim Christensen:
Actually, a ferrite bead isn't an inductor until you pass a wire through it.   :popcorn:
