Schurter Releases Ultra-Thin, High-Power Coin Cell Supercapacitors
The coin cell supercapacitors offer up to 1,500 mF of capacitance and 5.5 V operation for power supplies, medical equipment, electronics, and wearables.
Schurter has introduced a new line of coin-cell supercapacitors for applications that demand compact energy storage with high cycling endurance. The series includes two mounting variants, the SCCA for horizontal PCB mounting and the SCCC for vertical mounting, giving designers flexibility depending on board layout constraints.

How Do Coin Cell Supercapacitors Differ from Batteries?
Supercapacitors occupy a middle ground between conventional electrolytic capacitors and rechargeable batteries. According to Schurter, their energy density is roughly 10% that of a comparable rechargeable battery by weight, but their power density is ten to one hundred times greater. That tradeoff makes them well-suited for applications that require rapid charge and discharge cycles rather than sustained energy delivery over long periods.
Cycle life is another key differentiator. Where rechargeable batteries degrade after hundreds to a few thousand cycles, supercapacitors can endure many times that, making them a practical choice wherever frequent switching loads or periodic backup events are expected.

Schurter’s Coin Cell Supercapacitors
The Schurter coin cell series supports operating voltages up to 5.5 V and covers a capacitance range of 100 mF to 1,500 mF. Key electrical characteristics include low leakage current and a compact form factor that fits space-constrained designs.
Primary use cases include real-time clock (RTC) backup, memory backup, battery-swap ride-through, and triggering LED or audible alarms during power interruptions. The parts are also applicable in renewable energy systems and medical devices where reliable, maintenance-light energy storage is a priority.
The SCCA and SCCC coin cell supercapacitors are available now. Engineers evaluating parts for backup power or energy-buffering designs can reference Schurter’s product pages for detailed electrical parameters and mounting dimensions.
