Identifying a fuse

[deisenberg]

I have a PSU from a Sony dvp-cx985v disc changer that I some how popped an on board fuse, two actually. At least I believe they are fuses. Both look the same, see picture. I can't figure out how to identify it for the life of me. It's the green with 1 black strip, item pcb number p502

Part number in the schematics is 9-885-024-65 labelled as a link IC - no idea why as it's for the -11v rail.

Thanks everyone!

Edit: added model of sony disc changer

Picofuse?

looks like a zero ohm resistor

I'd agree if the black stripe were in the middle, which it is not. Fuses are essentially zero-ohm resistors until they become open-circuit resistors.

P is an unusual prefix for a fuse, however. Looks like there's something on the PCB under the fuse. Perhaps a better look at that might be helpful?

It would be a Japanese-make part and hard to know who makes it. In North America Littelfuse is the only thing close, and best to use a slo-blo part as many Picofuses are super fast and not ideal where inrush currents happen.
It should have colour-coding beyond one stripe so you know what the fuse's value is and don't mix them up in Production. If the other fuses are different value but same markings then I would be puzzled or tend to think it's zero-ohm jumper.

9-885-024-65
is described as
"Ic Protector 20N1000"

which from more googling is a 1A Fuse

Ah, and of course replacing the fuse won´t help as it blew for a reason probably

Here is the PCB with out the pico fuse. Green fuse above it with a red strip is the other that is dead as well. P301 9-885-036-14 LINK, IC.

Thanks your google fu is much better then mine!

Also the problem was caused by myself, I tried to power an Adriuno mega from the 11v rail and that's when the -11v stopped working. It's possible I shorted it out.


edit: For anyone else that has this issue

P301 9-885-036-14 LINK, IC is a 20N2000 is a skygate 2a/250 fuse.
P501 9-885-024-65 LINK, IC is a 20N1000 is a skygate 1a/250 fuse.
I used https://www.jotrin.com/ to pull up the details.

Thanks everyone for your help!
