Super capacitors are perfect for applications where the capacity of a standard electrolytic capacitor is too small and a rechargeable battery is bigger than needed. This 1.5F capacitor will run an LED / Arduino board for 15-20mins

Features:

1. Capacitance : 1.5 F
2. Maximum operating voltage: 5.5 V
3. Body shape: Coin type(multi-layer structure)
4. Tolerance on capacitance: -20 to 80%
5. Internal resistance(max.) : 30 ohms
6. Category temperature range: -25?C to 70?C
