Re: FIC VA-503+ best replacement for Vcore caps
Hi all,
I stumbled onto this thread and am dealing with a VA-503+ recap, myself. I went onto mouser.com / digikey.com to find suitable caps and realized I needed the ESR. To that end, I recently discovered / bought an LCR-T4 Mega328 which seems to do reasonably well with ESR measurements.
Long story short, I popped off the caps from the board that looked good and measured them as follows. (Please note: these are my measurements of capacitors which are old, unknown whether the caps are completely out of spec & unknown whether my measurement device is accurate. In other words, caveat emptor!)
In addition, I measured the physical dimensions of the caps as follows:
Capacitance: width (mm) x height (mm), lead spacing (mm)
1500uF: 8 x 16, 3.5
1000uF: 8 x 12, 3.5
10uF: 4 x 8, 2.5
All caps are 105C rated on my board.
On my board I have 8 x 1500uF caps, 4 x 1000uF caps and 22 x 10uF caps.
Hopefully this well help the next person looking to recap a VA=503+. I'm going to look for capacitors now...
