arumblack Posted January 23, 2004 Report Share Posted January 23, 2004 what parts is it possible to put in backwards on the core.i know... diodes, the electrolytic caps..the regulator the rectifier , transistor,and the ic's. anything else? the other caps or the crystal?

Steven_C Posted January 24, 2004 Report Share Posted January 24, 2004 crystal can go in either way. Low value caps that are non polarised, like 10n can go in either way. Quote Link to comment Share on other sites More sharing options...
arumblack Posted January 25, 2004 Author Report Share Posted January 25, 2004 that's what i thought.just to be sure, how do i know wich caps are polarized?this would be clearly marked right? Quote Link to comment Share on other sites More sharing options...
pay_c Posted January 25, 2004 Report Share Posted January 25, 2004 Caps which are polarized are either clearly marked with a + (or -) and/or have a longer and a shorter leg (longer one always +). Quote Link to comment Share on other sites More sharing options...
arumblack Posted January 25, 2004 Author Report Share Posted January 25, 2004 gotcha, thanks...maybe this should be in the FAQ? Quote Link to comment Share on other sites More sharing options...
Echopraxia Posted September 28, 2007 Report Share Posted September 28, 2007 Hello I know it an old topic but I am new to this. I just put together my first module and started with the IIC module for my MBSEQ 3.2 All is good but I had a question about the capasitors direction. I am using the smash tv board first edition. In the diagram on smashtv there is one 15 pf cap facing one way and right next to it is another 15 pf cap facing the other way. Right below that there is a 100 nf cap that I am not sure which way it should go. The one that is directly to the right of the crystal. How can I determine which way a cap goes everytime? Also about the leds on the IIC board can they go in either way. I remember reading a post about which part of the led is positive and which is negative but I can't seem to find it now. I attached a gif of which ones I am talking about. Quote Link to comment Share on other sites More sharing options...
