Just about to design a new board and need to use some zero ohm links to allow easy circuit isolation incase of any hardware debugging. Going to use a 1205 package. It's listed at 1/4 Watt. +/- 5%. Hmm, does that mean that you get some zero ohm links that amplify? ;) How does that work then? How much current do you have to put through zero ohms to get 1/4 watt power consumption? Ok, zero ohms must be a very small resistance. I wonder what it is? There must be a maximum current allowed. I simply can't believe that a zero ohm link in 1205 package can take, say, 100A. :D
zero ohm links, 1/4W ?

I would assume there is some current limit as you said. The package you want is a 1206, not a 1205, btw. Unless you want to use the smaller ones, in which case the package you want is 0805. Unless you want to use the *really* small ones, in which case 0603 is your best bet (but I wouldn't recommend going that small) Mouser or digikey will sell them to you 1000 to a reel for next to nothing.
