There are 10 47uF caps on an SE/30 motherboard: C1, C3, C4, C5, C7, C8, C9, C10, C12, C13.
Understand which caps must be changed, what the leading brand names are, exactly how to utilize the Mouser internet site as well as review the capacitor requirements. See just how I choose caps for the Macintosh SE/30 motherboard.
I do not like fluid electrolytes, so I directly will not make use of Polymer “Hybrid” Aluminum Electrolytics; yet I detailed that Hybrid cap since it practically will function great and also transcends to a routine light weight aluminum electrolytic.
SE/30 MOTHERBOARD CAPACITORS.
Instead than provide you a Mouser Cart for the SE/30 motherboard, I rather give web links listed below to specific capacitors on Mouser. That offers you flexibility to select a Can-shaped capacitor for a supply appearance, or your favored tantalum.
For the “supply appearance,” choose the “Panasonic OS-CON.” They have the most affordable ESR, however leak is two times Polymer Tantalum.
Desire the most affordable Leakage Current? Opt for the “Kemet SOLID 25V Mid-height.”.
If you desire the best Tantalum listed below, in regards to being much safer from a voltage spike that could eliminate the cap, the “AVX Polymer 25V Full-height” is suitable, albeit a little bit expensive. Also a 16V Polymer Tantalum is “secure” with the SE/30 motherboard’s 12V however, so practically any one of the Polymer Tantalums listed below are great selections for that application.

⚠ SOLDERING ADVICE! Maintain your 300 ° C to 350 ° C welding torch time to 3 secs or much less for either side of the capacitor, particularly for Polymer kinds! The Polymer extremely gradually weakens in time, however warm speeds up that destruction!

✴ NOTE: CAN-shaped Polymer Aluminum Electrolytics like OS-CON have greater leak present than Polymer Tantalum, and also a lot greater leak than Solid Tantalum or normal fluid-filled Aluminum Electrolytics. That leak specification does not matter for the SE/30 MEGABYTES, yet is a concern in circuits where reduced power issues, like battery-powered gadgets.
