The Vinatech VEC3R0348 QG is a supercapacitor (ultracapacitor) designed for applications requiring high power, fast cycling, and a long lifespan. With an energy storage capacity of 4.25 Wh and a maximum power output of 11.25 kW, this device, housed in a compact package (Ø 60 × 138 mm), offers an attractive alternative to conventional energy storage devices.
Electrical performance
- Voltage and capacitance: 3.0 V at 3400 F (3.4 kF).
- Current delivery: Thanks to the extremely low ESR of 0.20 mΩ, peak currents of >3000 A are achievable, making the capacitor suitable for powerful energy pulses.
Lifespan and reliability
- Cycles: More than 1,000,000 charge and discharge cycles – significantly more than rechargeable batteries.
- Temperature resistance: After 1500 hours of continuous use at 65 °C, the capacity of >80% is maintained and the ESR increases only minimally.
The VEC3R0348 QG is suitable for applications such as emergency power supplies, peak-power buffering, start/stop systems, robotics and medical systems, where fast energy delivery and high reliability are essential.
This supercapacitor combines high power density with a robust lifespan, making it a solid choice for engineers seeking reliable, low-maintenance energy storage.
