What is this?

[Sanghera]

Hi,
Would anybody be able to tell me what this is? It is on a small transformer, but it doesn't look like what I know.
Thanks for the help guys.
I really appreciate it.

It almost looks like a 2 amp fuse. Do you have an ohmmeter to check continuity thru it? Is that one of those "wallwart" transformers?

If it is in series with the winding it could be a thermal fuse link.

I think that it is a 2 amp fuse because if you look at it close enough it has a 2 or something on it. If so, can I replace it with a inline 2 amp fuse? Also, how can I tell if it is in series with the winding?
Thanks.

Yes, it can be replaced by an inline 2 amp fuse. It looks to be inline, wire -to- fuse -to- winding in -to- winding out. I would check check the continuity thru the fuse first though. If the fuse is ok then check the continuity of the transformer windings. Sometimes the winding blows first, protecting the fuse in these small transformers.

Okay.
Thank you all very much for your help.
I really appreciate it.
We are going to replace the fuse.

Usually the reason the fuse is placed in or on the winding is that it is the thermal type, It opens with temperature not current, for current it can be place anywhere external to the transformer.
it looks like it has 120c marked on it.
