Ultra Small Power for Space‑Constrained Designs
The SIHC0613‑3R0‑7F is a 3.0V 7F sodium ion hybrid capacitor that packs serious performance into a 6x13mm cylinder weighing just 0.9g. It combines a NaFePO4 cathode with a hard carbon anode, delivering higher energy density than EDLCs, excellent power delivery, and reliable operation down to -40°C. With a 50,000‑cycle life and sodium‑based (non‑lithium) chemistry, it’s a safe, cost‑effective choice for IoT sensors, electronic shelf labels, and backup power.
What’s Inside
Cathode: NaFePO4. Anode: Hard carbon. Separator: Ion‑permeable membrane. Electrolyte: Organic system. The aluminum shell seals everything tight, and the rubber plug prevents leaks and shorts. Lead terminals are tinned copper‑clad steel for easy soldering and reliable connections.
Key Numbers at a Glance
Nominal voltage: 3.0V. Operating range: 1.5V to 3.6V (max charge 3.65V). Capacitance: 7F (measured between 3.6V and 1.5V). DCR ≤900mΩ, ACR ≤600mΩ. Continuous discharge: 40mA. Pulse discharge (<1s): 800mA. Max discharge: 60mA. Leakage current: ≤2.0μA after 72h at 25°C. Storage: 10°C to 40°C.
Built to Go the Distance
50,000 cycles is the headline—and it delivers. After all those cycles, capacitance stays ≥70% of initial value, and internal resistance stays within 4x the original spec. High‑temp/high‑humidity storage (60°C, 90% RH for 1000h) leaves capacitance ≥70% and resistance ≤2x initial. Long‑term storage? Capacitance ≥90%, resistance ≤2x initial.
