Capacitor Reference - PowerBook 1400cs
I'd recommend recapping the 1400cs at this point, if you're confident in your soldering abilities. They don't always need it yet, but they can occasionally leak or cause problems.
Reference Values
Logic Board
I'd recommend buying smaller diameter replacements for the 100uf caps to make it easier to solder the new ones in. There isn't much clearance with the original size.
| Value | Count | Type | Diameter | Height |
|---|---|---|---|---|
| 100uf 35v | 9 | Surface-Mount Electrolytic | 10mm | 10mm |
| 33uf 25v | 1 | Surface-Mount Electrolytic | -- | -- |
Display (Sharp LM80C24)
Some 1400cs units shipped with a Hitachi LCD instead. I don't have the cap values for that one yet.
| Value | Count | Type | Diameter | Height |
|---|---|---|---|---|
| 33uf 10v | 1 | Surface-Mount Electrolytic | 5mm | 5mm |
| 10uf 16v | 1 | Surface-Mount Electrolytic | 4mm | 5mm |
| 3.3uf 50v | 4 | Surface-Mount Electrolytic | 4mm | 5mm |
Backlight Inverter Board
| Value | Count | Type | Diameter | Height |
|---|---|---|---|---|
| 10uf 50v | 1 | Surface-Mount Electrolytic | ~6.2mm | 5.5mm |
| 2.2uf 50v | 1 | Surface-Mount Electrolytic | 4mm | 5.5mm |
