I am stripping parts from TV circuit boards, I keep finding this. Some circuit boards have 2, some have 1, some have none.
I assume they are chokes they have only 2 wires. Wire is would on a ferrite piece with a magnet between the ferrite and the plastic base. The heat shrink plastic keeps the magnet from falling out. They look just like these but these have no magnet. They all have 2 wires. One if these in the photo has 3 pins but wire goes to only 2 pins.
