Guest AdamB Posted December 18, 2002 Report Share Posted December 18, 2002 So i go th the electronics store in Toronto(a hour drive from home) and get my parts. They didnt have thr BC337 transistor for the displat part of the core module. so the book said thst a 667 was the equiv. . not i think the part number is BC 667 but i may be wrong. i cant find any pinout forthis part, and need to make sure the pins are in the right place. Thanks all...ADam Quote Link to comment Share on other sites More sharing options...

TK. Posted December 18, 2002 Report Share Posted December 18, 2002 Hi Adam,based on this schematic: http://users.auth.gr/~mixos/projects/pcb/sensors/001/index_en.htm the pinout is the same, but the BC667 seems to be a PNP instead of a NPN - the polarity is exchanged, therefore the transistor has to be connected on a different way. Do you know, how to fix the circuit, or should I draw a schematic?Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
