SIHC0613-3R0-7F Sodium Ion Hybrid Capacitor | 3.0V 7F, 50,000 Cycles, Wide Temp (-40°C to 70°C)

Product overview

The Ecolto SIHC0613-3R0-7F is an ultra-compact, high-performance 3.0V 7F Sodium-Ion Hybrid Capacitor designed specifically for space-constrained and energy-demanding applications. Utilizing an advanced NaFePO4 cathode paired with a hard carbon anode, this cylindrical cell (6x13mm, weighing just 0.9g) bridges the gap between traditional EDLC supercapacitors and batteries. It delivers significantly higher energy density, safe non-lithium chemistry, exceptional pulse discharge capabilities, and a reliable 50,000-cycle life—making it an ideal, cost-effective power solution for next-generation industrial and IoT hardware.

Key features

• Extreme Cycle Longevity: Engineered for 50,000+ deep charge/discharge cycles, maintaining >=70% capacitance retention and outstanding internal resistance stability over its operating lifespan.

• High Pulse Power Delivery: Supports a continuous discharge current of 40mA and handles peak pulse discharge currents up to 800mA (<1s), perfect for bursts of wireless data transmission.

• Wide Operating Temperature Range: Operates reliably in harsh environments from -40℃ to 70℃, ensuring performance stability where standard lithium options fail.

• Enhanced Safety & Compliance: Built on stable, non-lithium sodium-ion chemistry enclosed in a robust aluminum shell with a secure rubber plug seal. Fully certified under UN38.3 and MSDS for safe, hassle-free global shipping.

• Ultra-Low Leakage Current: Features an exceptionally low leakage current of <=2.0μA (after 72 hours at 25℃), conserving critical energy during prolonged standby periods.

Built to Go the Distance

The headline is 50,000 deep cycles—and the cell delivers. Engineered to withstand rigorous long-term deployment and harsh environmental aging, its key durability metrics include:

• Extreme Cycle Life: Retains >=70% of its initial capacitance after 50,000 full charge/discharge cycles, with internal resistance remaining well within 4x the original specification.

• High-Temp / High-Humidity Stability: After undergoing accelerated aging tests at 60℃ and 90% RH for 1,000 hours, the cell maintains >=70% capacitance and keeps resistance inflation under <=2x the initial value.

• Extended Shelf Life: Demonstrates excellent long-term shelf stability, retaining >=90% of its capacitance with a minimal resistance change of <=2x when stored.

Applications

• IoT Sensors & Edge Devices: Provide robust backup power and pulse current capabilities for smart sensors, environmental monitoring nodes, and remote industrial tracking hardware.

• Electronic Shelf Labels (ESL): Act as a maintenance-free, long-life energy storage component to handle screen refreshes and wireless data syncing in retail environments.

• Smart Utility Meters: Deliver the necessary peak current bursts for automated water, gas, and electricity meters to transmit readings via cellular or RF networks.

• Automotive & Industrial Backup Systems: Serves as a reliable hold-up power source for dashboard electronics, data loggers, and critical actuators during unexpected power interruptions.

• Asset Tracking & Logistics: Offers a lightweight, wide-temperature power solution for active RFID tags and fleet tracking hardware subjected to harsh transit climates.
