Question about Fuse Ratings
 

I'm in the process of building a 70Mhz DDS frequency generator. I've
sourced all of the parts but I have one snag. The schematic calls for a
fuse 32mAT. What I don't know is if that is a rating for a fuse or some
kind of part number. I thought that fuses were rated in amperes, so I don't
know where the T comes from. The Frequency Generator I am building is from
the Octrober 2003 issue of Elektor electronics. So this is probably a
European part number.

I appreciate any help I can get on this. Thank-you.

32 milliamp (0.032 amps - very low current!) The T may be a size or a speed.
Europeans use a smaller physical size of fuse that the old US 1/4" style.

I'll bet it isn't terribly critical. What kind of circuit is it in?

"T" = time delay fuse not a quick blow one :-)


The fuses usually have a spring that can be seen through the glass

Please don't take this the wrong way, do you hold much chance of getting a
working unit if you can't work out what a 32m/a T fuse is

;-)

Don't be too tough. It's not easy for Yanks to figure out European designs
etc. I've worked on all sorts so I'm not too puzzled.

Yeah, good point
