Question about 0.1 uf film caps

chevy2410 · 21st January 2006, 06:08 PM

Hi all,

I've got a question about the 0.1 uf film caps. I just recieved BrianGt's Lm 3886 stereo kit and was wondering.... The 3 0.1 uf square blue caps, on one side they have a small white line that I assume indicates negative. Now I wanted to know when I go to solder them to the pcb on C3, C4 and Cz which side is negative and which is positive? I saw something awhile and can't find it, but I think C3 and C4, when soldered on, negative is on the botton, but I'm not sure about Cz.

thanks,
Chevy

Film caps are not polarized.
Install it either way... you'll be fine.

Thanks for the info head_spaz! I finished soldering the amp board and now moving on to the PS board.

Cheers,
Chevy
