I am replacing the caps on my G3 DV logic board and having some trouble identifying a cap. I think it's 47uf 25V, but I'm having some trouble confirming that. Still learning about identifying caps. The cap's markings show E2 470E UD. Just a google search for that string pulls up the data sheet located here but still having some trouble reading out that value.

Good find on the datasheet. On the first page, in the lower left quadrant, it says that the "E2" is the lot number, which we can ignore, and the "UD" is the "series", which is the specific model line of capacitors from this manufacturer. It also says that the "470" is the capacitance code and "E" is the voltage code, and that "E" means 25 volts. The next page has a chart that says that "470" means that it's 47uF. So, 47uF 25V.
The datasheet also gives physical dimensions (which are largely standardized), so you can find substitutes from another manufacturer that still fit the board footprint (I've had replacement cap kits that don't control for this, which can be a pain). | Posted by: mcbeav on 2024-07-20 11:44:35

Thank you for the help! I really appreciate the detailed breakdown! | | 1 |
