I'm seeing photos which appear identical, called either Coupled Inductor or Common Mode Choke.
Aside from ratio, what's the difference?

How low is "low"?Common mode chokes ... low-frequency current through them cancels
I thought coupled inductors don't store energy, and just transfer the energy immediately to the secondary. Wrong?Inductors used for energy storage...
Won't that reduce inductance?... are wound on cores with low effective permeability
That increases inductance, right? Meaning flux, right? How does that affect storage?Common mode chokes, with rare exceptions, are wound on cores with very high permeability, typically 5000 or more and typically ferrite.
meaning low-current? How low?For signal applications
confused, because those usb-cable chokes have no leads at all...ferrites that are often found on things like video cables and sometimes USB cables are common mode chokes, though they are also made with "lossy" ferrite so that they behave as if they were frequency-dependent resistors in series with the lines.
Which other thread are you referring to?How many threads need to be started on the same subject by the same member??
You are the same "johnyradio" that has all of the other treads on this subject aren't you? They could have and should be just one thread. Asking the same thing over and over again in a different way and different threads won't get you different results.Which other thread are you referring to?
I had an accidental duplicate post. I deleted it.Asking the same thing over and over again in a different way and different threads won't get you different results.
You don't get it. All of your posts on current transformers could have been in one thread, not strung out all over the forum.I had an accidental duplicate post. I deleted it.

My other posts are different questions .
Thx
