This is a 3.5uf cap, right?

Forgive me, but I only want to replace this once. Talking about the yellow one...

3uF actually.

To calculate cap codes: first 2 digits times the multiplier (third digit - 5 means 100000).
This gives 3,000,000pF or 3uF.
The j is the tolerance code, 5% in this case.

Here is a quick calculator.
Saves some math with lots of zeros. 🙂
