Supercapacitors / Ultracapacitors

Supercapacitors, also known as Ultracapacitors, are high-capacitance energy-storage components designed to deliver and absorb electrical energy rapidly. They bridge the gap between conventional capacitors and rechargeable batteries, offering significantly higher energy storage than standard capacitors while providing faster charge and discharge capabilities than many battery technologies.

Supercapacitors are characterized by high power density, very long cycle life, low equivalent series resistance (ESR), and excellent charge/discharge efficiency. They are available in various capacitance values, voltage ratings, form factors, and configurations, including single-cell and multi-cell modules. Common applications include backup and hold-up power, memory and clock backup, energy harvesting, regenerative braking, power smoothing, peak-power support, industrial equipment, automotive systems, renewable energy systems, and portable electronic devices.
