PCB fuse types

[habanerocat]

I found a faulty PCB fuse in a PSU.

It's labelled as H 5A. So I presume it's a 5 Amp, but is it a quick or slow blow type? It's on the output side so I assume it might be fast blow but as it's soldered in I'd like to get it right and not have to dig it out again.

Is there a way of classifying these PCB fuses? A guide or chart?
I can't find anything on them at all.

Thanks,
Habcat.

See atached.

Are they colour coded or something?

Thanks, but how do I know if it's slow or fast acting?

Re: PCB fuse types

no idea - maybe the letter in the circle.

your foto is too crap to see it though.
there are about 5 speeds btw.

Ok Thanks, it's a H in a circle. I don't know what it means either and can't find out. I'll go with a quick blow as it's on the output side of the PSU and hope for the best.

Thanks again!

LittleFuse use Green color body for Fast-Blo, Yellow for time-delayed/Slo-Blo.

Thanks, I must remember that.
