Aug 29, 2014 at 0:02 comment added Michael George @ThePhoton I've seen them in an old circuit (PCB). The numbers are not printed on the side, they are printed on the top (plan view).but I'm not sure that these are actual model numbers because I searched on google and I've found No results. That's why I'm asking here.
Aug 28, 2014 at 23:53 comment added The Photon Where did you find them? In a catalog? On EBay? In a drawer? What do you mean by "their numbers"? Are these numbers printed on the side? Or are these actual model numbers?
