Hi all. What fuse is this? It has T2H250V written on it. I believe this is slow blow 2A? It came out of an old TV. Where can I see an explanation of the color codes?

Is this too much voodoo?

Appears to be a 2amp normal glass fuse. Check bottom of this page for "four band" fuse: https://slimlab.net/mirror/fusecolours/fusecolours.htm

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

Thank you, that explains it. T2H = Slow blow 2A ceramic package

Wide blue band = Normal speed
Red-black-red bands= 2A

Not sure why they disagree on speed though. Slow blow should be a wide green band.

The band may have discoloured over time and slow/normal/fast are relative definitions. Slow/fast compared to?
