I saw this type of transformer, but I could not find it anywhere,
nobody now what is it ?
What type of transformer is it ? How many spire do they have, which
voltage ???
Any information will be appreciate.
Thanks,

These are usually used with telephone lines.

As has been pointed out, they are 1:1 transformers used for isolation.
There's nothing magic about "600 ohm to 600 ohm".
Get two identical audio transformers. Connect both secondary windings,
or both primary windings, together. The two remainding windings, one
one each transformer, are your new in/out windings.

Where was that posted by the OP? Line transformers often have functions beyond
isolation.

You asked this already, don't expect email when posting to a
newsgorup.
They are audio transformers, for applications where isolation is
needed
but not voltage step up or step down is needed. |
