Supercapacitor 4.7F 2.7V — Compact Energy Storage
The 4.7F 2.7V Supercapacitor is a compact ultracapacitor that stores enough energy for brief backup power, RTC keep-alive, and small energy harvesting buffers. Smaller than the 100F version but still far more energy storage than any standard electrolytic capacitor.
Technical specifications
| Capacitance | 4.7F |
|---|---|
| Voltage | 2.7V (max) |
| Type | EDLC (Electric Double-Layer Capacitor) |
| Cycle life | 500,000+ charge/discharge cycles |
