As it says on the tin, 220 v 16 pin resistor DIPs is all the information my book, 123 robotics expmeriments for the evil genuis, seems to give in the text to describe that part. It does not state the resistince, but on the pictures in the example, the part number is (seemingly) 4110R-1, and on the next line221. I've found that part number for sale, I think, but no confirmation of what it actually is. I'm not terribly confident on what the bottom line on the part says, it has several characters/markings I can't make out, denoted by ?:
That might be a B.
Also, by convention what are these numbers trying to express?
Thanks for any assistance!
