Sorry if this is not in the right section ( Mods please move if needed ).

I'm looking to purchase 0.2ohm 1 or 2 watt resistors. If tried multiple places but it seems like a very scarce resistor to come by.

Is there a place where I might find it? Preferably Western Cape if possible.

Thanks.
 
0.2 is a non-standard value, that is why you are not successful. The closest value is 0.22

Maybe. Space? Availability? etc. ;) or just use one o.22 ohm.

0.1Ω is quite common... plus honestly resistors are tiny and you can almost always get them in series. Surface mount or through hole, there are easy ways to do it.
Agree with just using a 0.22, depending on his application, in most cases should have the same effect.

I do have enough space to do that. Thanks for the idea!

Put a photo..... I find that very hard to believe. Unless you doing this with a pick and place machine.
Because looking at the board you showed it is easy to put 2 in series pretty much anywhere.... you have loads of space.
 
If I solder 2 through hole in series and then on to board, why would that be hard to believe?

Because you can orientate them any way you like, they can hover in the air, they can be stuck parallel to each other even. You can even lie them on other resistors as long as you insulate. Unless they are going into a board for something like a cellphone (even many of those they would fit), I don't believe that you can't fit them.

Lie them to the top right with wires to them.
The change in inductance will not affect the operation of the device.
You could alternatively put them together with wires to the points and then cover them in insulation or woodglue to avoid shorting.
Trust me, did much tighter stuff than this on smaller boards.
