I've reconsidered the contents of this post because I realised I was having a bit of a "thick" moment.
When considering the resistor type for the miniE board, can anyone recommend what wattage / tolerance I should be looking at? Listed components below.
Additionally - does the 0207/10 mean anything important? Googling it reveals nothing useful.
R2 500 Ohm RESISTOR 0207/10
R3 1k Ohm RESISTOR 0207/10
All help appreciated!
0207/10 is the size of the
0207/10 is the size of the resistor: 02 = 2mm wide, 07 = 7mm long, /10 = 10mm lead spacing. An 0207 resistor will always be below 1/3rd watt, so wattage isn't terribly important here. Tolerance will depend on the application, but 5% is pretty standard. You'll find that Vishay-Dale makes some excellent Mil-Spec resistors in about that size that run 1% tolerance, I tend to use these for analog uses, like the button chain setup to one analog input on the DollyShield.
Here, for example, is a 499Ohm resistor (which will work fine for 500 Ohm), and will fit that footprint: http://www.mouser.com/ProductDetail/Vishay-Dale/RN55D4990FB14/?qs=sGAEpiMZZMsPqMdJzcrNwvkdYAxQ3%2fr%2f7I3qZZdc9pw%3d
