Now obselelte. What do I call them? And where do I find them on DK?

Note these are listed under cores, 'cause they have a hole, no leads.

You dislike FeroxCube? Oh! How about Richco, Steward, Bourns, J.W. Miller, Murata, Pulse, TDK, and many others?

'hollow beads'

Do a search on Google images for "ferrite bead" and click on one of the subsequent candidates and there may be a link to where google found it.

Murata sells ferrite beads of several small form factors like that too.

Ask Fair-rite to cross it for you. Let them do the work!

I have a bunch of old Ferroxcube beads/cores that I bought when I was about 30. The ones you link to are pretty low frequency devices, given that their impedance looks like it peaks in the 30-MHz region.

I use pairs of beads of about that diameter but half as long, one each of type 3E2A (high frequency) and 4B (low frequency).

Thanks, I just couldn't find the right search terms/ designaters on DK. (I selected tubular cores.. should have been solid. go figure.)
