Going back I had picked up some oddball resistors. They have the standard bands on them but were is packages using letters and numbers (ie) R-A3D3 R-A4D3K etc. How do these letter codes work?

Are they chip resistors?

No I actually got these as a resistor package from AES. Standard ones are 5K, 10K, 1M etc but these used other odd coding like above.

Sounds like 3.3 ohm and 4.3k ohm. A is probably a tolerance rating like 5%; D for dot (?)
