SIHC0415-3R0-4F 3.0V High-Pulse Sodium-Ion Coin Cell Battery

Product Overview

The SIHC0415-3R0-4F is a cutting-edge 3.0V, 3mAh Sodium-Ion button cell battery engineered for high-performance, high-rate charge and discharge applications. Combining a compact coin-cell form factor with exceptional thermal stability, this sodium-based cell delivers a reliable power solution across a wide operating temperature range (-20°C to +60°C). Designed with an industry-leading safety profile, it features extremely low risk of rupture or ignition under stress and supports safe 0-volt transportation, dramatically simplifying shipping logistics and reducing regulatory compliance burdens.

Key Features

• High-Rate Pulse Performance: Supports standard 1C charging/discharging (3mA) and extreme continuous high-rate currents up to 25C (75mA), making it ideal for high-pulse power demands.

• Advanced Sodium-Ion Chemistry: Offers a safer, highly stable alternative to traditional lithium chemistries with zero risk of thermal runaway, explosion, or catching fire under mechanical or electrical abuse.

• Hassle-Free 0V Transportation: Can be fully discharged to 0 volts for transport and storage without degrading the battery's capacity or life cycle, eliminating strict lithium shipping restrictions.

• Wide Thermal Tolerance: Reliable operation in harsh environments with a discharge and charge temperature range spanning -20°C to +60°C.

• Compact, Reliable Form Factor: Optimized in a micro-sized coin cell profile, providing a low internal impedance (≤ 600 mΩ) and steady 3.0V nominal voltage output.
