I bought these.

Yageo 47.5K ohm 100ppm SMD (Surface Mount) Thick Film Resistor 0402 1% 1/16W RC0402F (Continuous strip of 500)

I have modded 3 GS's so far and they are running fine at 1150Mhz for 4 hours.

I need to get a better magnifying glass to do the rest of these.  It's like soldering a grain of sand.  Are these OK to use?  Is 1/16 ok?



think youll find that on SMD resistors its more the series that dicates the wattage. In this case 0402 is the correct series. 1% is great to. Should be ok.
Instead of usig a solidering iron i highly suggest getting access to a hot air station. i soldered smd before but never this small.
Hats off to ANYONE soldering these, thats serious skill. im using my hot air station on them Smiley

Just watch out not to blow any SMD away. I use kapton tape but sometimes I see that a few caps/resistors blew off (Even at speed 1 on my rework station :S).

Also, I got a few 49.9k Resistors like Wolfey did ("His mod", or whoever found it). I'll post updates on Monday (That's when I get them)
