Eaton XV series cylindrical snap on supercapacitor

Product Overview

Product positioning: Eaton XV series supercapacitors adopt an electrochemical double-layer capacitor (EDLC) structure, combined with high-performance materials, and are ultra-high capacity energy storage devices that can adapt to diverse current requirements from microampere level (lasting for several days) to ampere level (lasting for milliseconds).

Core strengths

Long lifespan: 10 years of working life at room temperature, 500000 cycles of charge and discharge life

Excellent performance: ultra-low equivalent series resistance (ESR) achieves high power density, and large capacity design achieves high energy density

Compliance: UL certified, compliant with ROHS standards, halogen-free, environmentally friendly and pollution-free
