Re: beads and zero ohm resistors

Hello John,
...

No.

Have a look at the video and the pics here:
http://www.we-online.de/web/en/electronic_components/produkte_pb/we-mpsb~1.php
to get an idea. I don't now how the produce the helix and how they fill 
the gaps with ferrite.
Some are at least produced as multilayer components, just like you would 
build a multilayer transformer coil or antenne on a PCB.

Cheers

Robert
