Have you ever wondered what the actual coil inside the Nu capsule looks like? Here’s a close-up. There’s 1300turns, gauge 46AWG, in that miniature, bobbin-less coil.

The Nu capsule is encapsulated in epoxy. Looking at that small coil, I suppose you will understand why.
It’s the secret ingredient behind the Nu.
