Electrolytic Caps....

Post by HRDROKN » Wed Jan 21, 2009 10:17 pm

Hey Guys....

Have a rookie question.... I want to be sure how to identify the (+) side of an electrolytic cap?

Hrdrokn, I usually just look at it and check for the + sign on the appropriate end. For non-polarized electrolytics, there is no + or _ to worry about.

The caps have a gray stripe on one side with what looks like a line drawing of a (-) sign? No (+) on them though. The pcb is marked for the (+) side so I'm assuming that they go a certain way.

Ooops, sorry, I meant the - sign. One way or another it is clearly indicated so as to not plug them in backwards. And yes, the side with a stripe is the negative side. I don't replace caps very often but I have never managed to replace one backwards. I haven't built anything (where I don't remember hooking 1 up backwards either) from scratch for almost 30 years so I'm sorry about the mistake!

Also, the plus lead is longer on radial caps. BTW, Marchand makes a fine crossover! =D>

If you do put one in backwards it will explode (quite often) like a bomb, spewing some ugly and hard to clean up residue throughout the immediate area. A co-worker of mine did that once during a bomb scare at the plant we worked in - it sure got their attention!
