I see only 2 wires. Then it is a choke, not a transformer.
There are millions of things that look like this but they are all different.

A choke has inductance that can be measured. It also has a small resistance and a max current rating.

I can't think of any circuit that needs a choke. About 45 years ago I had a vacuum tubes amplifier that used a choke in its power supply.

Chokes are still widely used today. Power companies use them to filter out harmonics and power factor correction - they are huge.
