- Peak current booster for motor or servo startups
- Solar garden light energy storage
- Camera flash capacitor replacement (check voltage)
Compatibility
This supercapacitor works with any DC circuit within its 25V rating. Common pairings include 3.3V and 5V microcontrollers like Arduino Uno, ESP8266, and Raspberry Pi through a charging circuit. For series connections above 25V, use balancing resistors to prevent overvoltage on individual cells.
Wiring Notes
Charge through a current-limiting resistor (e.g., 10–100 ohms) to avoid inrush current. Observe polarity if the capacitor is marked; reverse connection can damage it. Keep wire lengths short to minimize ESR impact.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, it can be used as a backup power source for Arduino's RTC or to stabilize the 5V rail, but requires a charging circuit to limit current from the Arduino's output.
Can I use this for starting motors?
Absolutely. The 100F capacitance provides high current bursts, ideal for overcoming motor startup torque. Ensure the motor voltage does not exceed 25V.
How do I charge it safely?
Use a constant-current source or a resistor in series with your power supply. Never exceed 25V. For fast charging, monitor the voltage and disconnect when full.
