SIHC0813-3R0-16F Sodium Ion Capacitor | 3.0V 16F | 50,000 Cycles Ultra-Long Life & Wide Temperature (-40°C to 85°C)

Product overview

The SIHC0813-3R0-16F is a high-performance 3.0V 16F Sodium-Ion Hybrid Capacitor (SIHC) engineered for demanding industrial and commercial electronics. By integrating an advanced NaFePO4 cathode with a robust hard carbon anode, this next-generation energy storage solution bridges the gap between traditional EDLC supercapacitors and lithium-ion batteries. It delivers significantly higher energy density than standard supercapacitors, while maintaining exceptional pulse power, rapid charge/discharge capabilities, and an ultra-long operating lifespan.

Designed with an inherent focus on safety and environmental sustainability, its non-lithium chemistry eliminates thermal runaway risks, making it an ideal choice for high-reliability applications such as IoT devices, smart utility meters, electronic shelf labels (ESL), and critical backup power systems.
