Why Choose Kamcap 85°C High Temperature Supercapacitors?

In demanding industrial and automotive environments, standard capacitors often fail due to electrolyte degradation at elevated temperatures. Kamcap’s HT Series (2.7V) is specifically engineered to overcome these challenges, offering superior performance where others compromise.


Exceptional Thermal Stability: While conventional supercapacitors experience a sharp increase in Internal Resistance (ESR) at high temperatures, the HT Series utilizes a specialized electrolyte formulation and advanced sealing technology. This ensures the 2.7V supercapacitor maintains a consistently low ESR even at 85°C, preventing energy loss and overheating during rapid charge-discharge cycles.


Industrial-Grade Reliability: Our 2.7V high-temperature series is rated for 1,000 hours of endurance life at 85°C under full voltage. This longevity is critical for mission-critical applications like smart meters and automotive electronics, where maintenance-free operation over a 10+ year lifespan is expected.


Optimized for Harsh Environments: With an operating range from -40°C to +85°C, these ultracapacitors provide reliable power backup and pulse current support in extreme climates, ensuring your devices remain functional from freezing winters to scorching industrial heat.

FAQ: 2.7V High Temperature Supercapacitors

  • What is the maximum operating temperature for Kamcap 2.7V supercapacitors?

    Our HT Series 2.7V supercapacitors are specifically engineered to operate reliably at temperatures up to 85°C. This significantly surpasses standard industrial capacitors, which are typically limited to 65°C or 70°C, making them ideal for high-heat environments.

  • Can I use 2.7V supercapacitors in series for higher voltage applications?

    Yes. You can connect 2.7V cells in series to achieve higher voltage requirements (e.g., 5.4V, 12V, or 24V). When doing so, we recommend using a voltage balancing circuit to ensure each cell operates within its rated 2.7V limit, extending the overall lifespan of the module in UPS or solar storage systems.

  • What are the main advantages of an 85°C rated supercapacitor over a standard one?

    The primary advantages are thermal stability and longevity. At 85°C, standard capacitors suffer from rapid electrolyte evaporation and ESR (Internal Resistance) spikes. Kamcap’s HT Series maintains low ESR and high capacitance retention, ensuring 1,000 hours of endurance life even at peak temperatures.

  • Are these 2.7V supercapacitors suitable for automotive Dash Cams?

    Absolutely. Our 2.7V high-temp series is a preferred alternative to lithium batteries in Dash Cams. They can withstand the extreme heat inside a parked car under direct sunlight (often exceeding 70°C) without the risk of swelling or explosion, providing a safer and more durable power backup.

  • What is the typical lifespan (cycle life) of the HT-2R7 series?

    Under normal temperature conditions (25°C), the HT-2R7 series offers a cycle life of up to 1 million cycles with minimal capacity attenuation (≤ 30%). This makes them virtually maintenance-free for the entire lifecycle of most electronic devices.
