Hi guys!
Long time no post! I bought a new (to me) car and it's got an issue with one of the modules. Some smart fellow took his apart in order to save the $2,000 USD that it would require to buy a new one and he found 3 regular capacitors on the board, one of which was shot. He replaced it and it fixed his problem. Cool beans!
OK, so I scanned my car the other day and it reports the very same issue and the symptoms are exactly the same. So...I'm planning on going in and finding out what the capacitor values are and ordering up all three.
This particular module resides in the engine compartment so higher temperatures are encountered. Anyway, one of the caps is 22μF/50v/105°C and they are through-hole regular caps. I was looking at digikey and can get the same thing in a through hole cap (CAP ALUM POLY 22UF 20% 63V T/H) with a higher lifespan etc.
I don't know a lot about capacitors or the differences between a 'regular' cap and a polymer cap but I do know in the computer industry they went away from 'regular' caps a long time ago.
My goal is to replace the 3 'regular' caps with really good modern caps that should not need revisiting. Are there any other differences that I'm not aware of or is it just a matter of match the specs and install them?
