Can anybody identify this component?

Hey there - I was looking at the PCB that is attached to a Dell laptop
battery. I noticed a very odd component. I then was looking at another
Dell laptop battery PCB, and noticed a similar component. Can anybody
identify what this is?

One of them had two of the pins shorted and about 45 ohms between the
third pin and the two shorted pins. The other had all three leads
floating with respect to each other.

Thanks,

Weird, if this were on a backlight inverter I'd have guessed PZT
transformer but it looks a bit small for that.

Beats me, but what you normally find on a battery pack is some sort of
"cell protector" and maybe a PEPI or some sort of short circuit
protector. The cell protector should be a chip, so maybe this is a
short circuit protector, but then why would it need 3 terminals.

Looks like an SC protector. Google for "sc protector".

Basically the device works as a fuse that can also be blown by an external
control current.

One of them had two of the pins shorted and about 45 ohms between the
third pin and the two shorted pins. The other had all three leads
floating with respect to each other.

The first one is normal case, the device with floating pins has done its duty.
