Comment on Pretty part of the week: Ruishen RSCM11548 3-winding common-mode choke

I just realised how hard it would be to manufacture this thing.
Imagine having to bend those copper wires into that shape around an already-existing toroid ring. Or maybe they glue together a few pieces of ring?

i would feed a hot metal stick into a U-shaped form, so it curls around the ring a few times, then cut it and let it cool and harden. they probably have a machine doing that.
