In Reply to: RE: Please recommend an audiophile fuse posted by Duster on July 06, 2021 at 21:45:08
I've indeed seen a handful fuses on Ali that seem interesting, but I'm afraid of putting a 500mA fuse when a 200mA is required...
Follow Ups:
The fuse value for a low-current device such as an audio preamplifier is not necessarily written in stone. Fuse values of less than 500mA for an analog device such as a preamplifier seems unusually low. Concern about safety or damage to the circuitry caused by a 300mA gap is a non-issue in this case, IMO. I wouldn't suggest doing so unless I would also do it for my own wants/needs, KanedaK. Perhaps another AA Inmate will toss-in their own 2 cents.
The designer of K's pre amp more than likely did the standard type calculation for the fuse. There are safety reasons for this and I know of no reason that these standard type calculations do not apply to a low current device and it seems to me, unless the designer made a mistake that putting in a fuse 2.5x higher rated than the person smart and well trained enough to design a commercial pre-amp would not be too kosher, unless I'm missing something.

It's not so unusual to use a more readily available 500mA fuse rather than a 200mA fuse.

"Look at the 20VA transformer in the table. Short circuit current is just over 2A, and full load current is ~170mA. This ideally requires a 200mA fuse, although a more readily available 500mA fuse will work."

See link:
What is usual or unusual is not the issue. The designer calculated for a 200ma fuse, not a fuse 2.5 times that current rating. Your example states that the 200ma fuse would be ideal. If 500ma would work as well as a 200ma fuse for protection than why would anyone use a 200ma fuse? It's not all that unusual for people to believe that the sun revolves around the earth. Apparently 26% of people in the US believe it. I could come up with one or two more examples of irrationality if I thought hard enough. Tweaker456

Give it a rest. You can beg to disagree with anything you wish to, but there is no great rule being broken that deserves your complaint to the moderator.
