6 FAQs about Super Farad Capacitor Safety

How long does a super capacitor last?

The life of supercapacitors will double for every 10°C decrease in temperature or voltage by 0.1V. Supercapacitors operated at room temperature can have life expectancies of several years compared to operating the capacitors at their maximum rated temperature. L1= Load life rating of the super capacitor (typically 1000 hours at rated temperature).

Can a supercapacitor withstand high temperature?

If this is not possible, decreasing the applied voltage to the supercapacitor will assist in offsetting the negative effect of the high temperature. For instance, +85 °C ambient temperature can be reached if the applied voltage is reduced to 1.8 V per supercapacitor.

Can acetonitrile supercapacitor outperform traditional capacitors?

This enhances electrical series resistance (ESR), and, as shown in Figure 2, can outperform traditional capacitors by a factor of two at -40 °C. KYOCERA AVX has conducted an extensive study of acetonitrile SuperCapacitor safety performance.

How many volts can a supercapacitor handle?

Individual supercapacitors are limited to 2.5 V (P Series reaches 5 V using two supercapacitors in series). As many applications require higher voltages, supercapacitors can be configured in series to increase the working voltage.

What is a super capacitor?

SuperCapacitors have now become commonplace components in many areas of modern electronic design. They bridge an important gap between batteries - used for high density energy storage, and electronic capacitors - for local power supply stabilization and decoupling.

Are acetonitrile supercapacitor safe?

KYOCERA AVX has conducted an extensive study of acetonitrile SuperCapacitor safety performance. Several notable tests and results are presented here to demonstrate the applicability of these devices in safety critical applications.
