Title: Power rating of the 0 ohm resistors?
Post by: Deke609 on August 10, 2020, 01:13:13 AM

What is the required power rating of the two 0R resistors? Less important question: are they used as fuses?

MTIA, Derek

IIRC 0 ohm resistors or "links" are used as short circuit jumpers of a sort.  Sometimes it is easier to install them than very short pieces of wire, especially in SMD applications.
All they have to do is handle the current in the design application. Current and voltage will determine the power rating  (P=I^2R).

Thanks Adrian. I seem to recall reading something to the same effect somewhere on this forum. If that's the case, I'll just use wire.

I do find it funny that they have a power rating.  I suppose that's more about the size they are than anything else. 

The teflon coated wire we provide is super nice, but it's also hard to strip the ends of a really short piece, so a 0 ohm resistor makes things much easier.

Cool. Thanks.

I deal with that by stripping the entire length of wire that I need, cut the removed teflon jacket to desired length, and slide back on. Being teflon, it slides on easily.
