Adjuncts in plugpack output cables

My guess also.

I've seen them. Depending on which end they're on, they're either there to stop radiated hash coming from the plugpack (switchmode), or, the equipment it's connected to inducing hash back up the supply cable.

Though for the latter, it would also be my guess that the equipment would have this ferrite suppressor built into itself in the first place, and not rely on the (perhaps unknown) plugpack manufacturer doing the job for them.

This being a generic plugpack, it strikes me as odd that they'd go to the cost of adding a relatively expensive suppressor (presumably at the plug end?) to insure against whatever it's connected to, that they have no real control over. And it's not their job anyway.

Yes they are awkward. But have a look at:

Sounds like a factory fitted ferrite bead, e.g:

Can you post a (web based) photo?

Yes, they are not unusual on plugpacks supplied with equipment, but on a generic individual plugpack I find it rather strange. Perhaps it's a big surplus buy where it was intended to go with another product?

Yep, ok, good point. All the more curious then... Would be nice if Bruce could post a photo.

Did you notice the schematic specifies D1 - 4 as 1N4001?

Has to be a typo.....
