High-Power Supercapacitors

Eaton Electronics High-Power Supercapacitors are high-reliability and ultra-high capacitance energy storage devices utilizing proprietary materials and processes. These supercapacitors feature low ESR, long life cycle, and low self-discharge. The high-power supercapacitors can be used as sole energy storage or with batteries to optimize cost, lifetime, and run time. These supercapacitors are UL-recognized and are maintenance-free. The high-power supercapacitors are ideal for backup power, electronics communications, electric vehicles, and IoT nodes.
