Electrolytic capacitors
Bulk input and output capacitors — ripple, ESR, and lifetime.
Aluminum electrolytics handle bulk energy and ripple current on power supplies. They are polarized: reverse voltage damages the part.
Key parameters
| Parameter | Notes |
|---|
| Rated ripple current | Must exceed supply ripple at frequency |
| ESR | Affects output ripple on regulators |
| Lifetime hours | Temperature drives aging; keep cool |
Pair a large electrolytic with ceramic bypass at the load for wideband decoupling.
