The Performance Characteristics of 3V Winding Supercapacitor：
High energy, high power series
Kamcap's 3v supercapacitor series is available in temperatures ranging from -40 to +65 °C and is suitable for long-term stability in high pressure environments.
SE/HE series kamcap high power supercapacitor products use a temperature range of -25 ° C ~ 70 ° C low leakage, suitable for long-term continuous discharge of small current.
SP/HP/LR seires kamcap super capacitor products use a temperature range of -40 ° C ~ 70 ° C low internal resistance, providing instantaneous high current output.
3V High Power Series: The Advanced Energy Solution
Kamcap’s 3V winding type supercaps (HP Series) represent a significant voltage upgrade from standard 2.7V cells, providing higher energy density and stability for modern electronic systems. Engineered for long-term reliability in high-pressure environments, these capacitors are the preferred choice for engineers seeking a balance between high power output and robust thermal endurance.
Optimized Voltage: The 3.0V rated voltage offers a higher energy buffer, reducing the number of cells needed in series configurations.
Broad Capacity Range: From compact 1F units for RTC backup to massive hp 500F cells for industrial power bursts.
Dual-Series Advantage: We offer the SE/HE Series for low-leakage, small-current discharge and the SP/HP/LR Series for instantaneous high-current demands.
Why Choose 3.0V Supercapacitors Over 2.7V?
When designing modern energy storage systems, upgrading from 2.7V to 3.0V supercapacitors (HP Series) offers significant technical and economic advantages. Here is why engineers are making the switch:
Higher Energy Density (23% Increase)
According to the energy formula ($E = 1/2 CV^2$), energy storage is proportional to the square of the voltage. A 3.0V cell stores approximately 23% more energy than a 2.7V cell of the same capacitance. This allows for a more compact device design without sacrificing power performance.
Superior Cost Efficiency & Simplified PCB Design
In common 6V, 12V, or higher voltage systems, using 3V cells reduces the total number of components needed in series. For example, two 3.0V cells can achieve a 6.0V system, whereas 2.7V cells might require more complex management. This simplification lowers the Total Cost of Ownership (TCO) and reduces the complexity of PCB layouts.
Enhanced Reliability in High-Pressure Environments
The Kamcap 3.0V series is specifically designed to handle high-pressure stability. By providing a higher voltage ceiling, these capacitors offer a larger safety margin against voltage spikes, ensuring long-term durability in mission-critical applications.
Superior Temperature Resilience for Outdoor Use
Our 3V winding type capacitors operate reliably across a wide temperature range from -40°C to +65°C. This ensures that critical infrastructure, such as Power Distribution Terminals (TTU) and Smart Meters, remains fully functional in extreme outdoor climates and harsh industrial environments.
Typical Application of 3V Winding Super Capacitor
Kamcap 3.0V ultracapacitor is widely applied into different industries. For example, it can be used in RAM, detonator, car recorder, water meter, electricity meter, gas meter, controller, vacuum switch, digital camera, motor drive and clock circuit. The 3.0v super capacitor also performs well in industrial backup power supply, toy, program-controlled switch, distribution Transformer supervisory Terminal Unit（TTU）etc.

Frequently Asked Questions About 3V 500F Super Capacitor
What is the maximum surge voltage for the Kamcap 3.0V series?
Our 3.0V HP series is designed with a surge voltage of 3.15V. This 5% buffer is critical for industrial power supplies, as it provides an extra safety margin against unexpected voltage fluctuations, ensuring the capacitor remains undamaged during transient spikes.
Can 3V supercapacitors directly replace 2.7V cells in existing designs?
Yes. In almost all applications, 3V cells serve as a superior upgrade to 2.7V cells. Because they offer a higher voltage ceiling, they provide a larger safety overhead and approximately 23% more energy density in the same footprint. This makes your system more robust without requiring a full PCB redesign.
What is the estimated cycle life and long-term reliability of the HP-3R0 series?
The Kamcap 3V series is engineered for extreme longevity, offering a normal temperature cycle life of over 1,000,000 cycles (measured at 25°C). For industrial users, this translates to a maintenance-free energy storage solution that can last for over a decade, far outperforming traditional chemical batteries.
How does the 3V series perform in low-temperature environments?
Our 3V winding type capacitors are built for resilience, maintaining stable performance in temperatures as low as -40°C. This makes them the ideal power choice for outdoor Smart Meters, TTU (Transformer Terminal Units), and automotive electronics where battery failure is common in winter.
Is it necessary to use a protection circuit with 3V modules?
When connecting multiple 3V cells in series to form a module, we highly recommend using a voltage balancing or protection circuit. This ensures each cell stays within its rated 3.0V limit, maximizing the overall lifespan of the system. (You can view our pre-built MK Modules for integrated protection solutions).
