Silicon Graphics System Capacitor Lists

[Docter60]

This thread hosts a collection of capacitor lists for various SGI boards (mainly for PSU recapping). The collection is not exhaustive and will be added to as more lists are provided. Feel free to notify me of any errors or requested additions.

Thanks for posting these up! I know they are in high demand

These lists have a big issue, without manufacturer name & family line...it's dangerous for PSU circuits. I was lead to believe that (with good reason) you're supposed to research what the OEM caps were and grab the correct upgrade (using cap charts) from either a newer family line that claims to be a transition from the one you saw, or shares the same intended usage to try to match-up ESR as best as possible with original caps. You don't just "find" a similar cap from another manufacturer and install it!

The reason it takes so long to develop a workable BOM is to FIND all the proper replacements to run the circuit as it was decades ago...not using different caps...similar caps.

If you stick a LOW ESR (new cap) in a deign never intended for it...you could actually do harm. PSU designs can be sensitive to changes in ESR due to oscillation requirements.

Matching ESR (at operating frequency, no less, since ESR measurements change versus frequency) can be a concern for some of the capacitors in the circuit. More important, for example, on the output capacitors than on the AC line side ones (for which ripple current is a larger concern), may or may not be important for various smaller capacitors in the control circuitry etc.

Hopefully people can contribute model data over time
