Hi.
I happen to have a bag with a component that I can't
find any data on.

It's made by "VAC", a german company.

It's like a dice in size and form. 17 x 18 mm and
13 mm hight (from the PCB). The upside is
marked "ZKB 472/142-80-W". Four pins at the bottom,
one in each corner and it's epoxy filled from the
bottom. I'v measured 1.20 mH between each
"pair" of pins, so it could be some kind of transformer...

I have found other ZKB xxx components made by VAC, and
they was all kinds of "inductors", "puls transformer",
"SCR driver/interface" and such like.

Since it gives the same mH reading on both coils (?), it
should/could be a 1:1 transformer, not ?

Anyway, if anyone have seen something like this before,
I'd be happy to hear about it !

Jan-Erik.
