Coin Cell Supercapacitors

Eaton Coin Cell Supercapacitors feature a high capacitance capability utilizing an electric double-layer capacitor (EDLC) construction. The capacitors offer low ESR for high power density with eco-friendly materials, which allows for a long cycle lifespan. The Eaton Coin Cell Supercapacitors are ideal for various applications, including utility meters, network switches/routers, motor control units, HVAC controls, Real-Time Clocks (RTCs), solar inverters, and more. All Coin Cell capacitors are lead-free and RoHS-compliant.
