I could really use everyone's help here. I've been trying to work on this for a long time. I am trying to rebuild a simple circuit board that has a bad component in it somewhere. It is a speed controller for a 120vac uh, um, fan, yea, that's it, a fan (actually it is a commercial food mixer, I know, I know this is a COMPUTER hardware forum, not a restaurant equipment forum - but this is the only place I was familiar with that had electronics experts.... Hey, it is an interesting exercise for all you folks who understand electronics. Plus, I build PCs, so.... Help already!) Please see the pics: http://picasaweb.google.com/smportis/SpeedController. Comments with the pictures. I can ID the resistors, no problem. 1. I can ID the capacitors, but can't find where to purchase them to match exactly. See below for my attempts to id and find matches. 2. I can't ID the diode - what are its specs? 3. I can't ID the black component - labeled as a "TR"? I need to purchase matching components. Have been looking at Digikey.com and Newark.com. Can the components experts help me? Thanks a ton! Scott ============================================== Components identified: There are 3 capacitors: 1. 473J 400v The cap pictured above has the code 473J which translates to: 47 * 1,000 = 47,000 pf or 0.047 uF The J indicates a tolerance of +/- 5% Size: 10 mm Long(L) x 9 mm high(h) x 5 mm thick(b).
