# What is this transformer-like component with only two leads

I found this while taking apart a PSU, the closest label was B1. It appears to be a transformer-like component with two leads, and the coils on the vertical part around the core seem to be connected opposite the leads. Googling the label got me nowhere.

Interesting. I got some leads on the inscription, but they all seem to point to the frame of the unit which is apparently called U3216. For example this –  AndrejaKo Nov 16 '11 at 12:26
Looks to me like it's just an inductor - kind of like a toroidal one with a closed loop for the induction core, just not in the shape of a toroid. –  Majenko Nov 16 '11 at 12:31
Dumping a 3000 x 2250 picture on us is ridiculous. It should be resized to 800 max. It wouldn't hurt to hold the camera still and focus more carefully either next time. –  Olin Lathrop Nov 16 '11 at 13:41

It would also help if you put a ruler next to it for scale. –  starblue Nov 17 '11 at 8:05
