Product Description
Power your most critical, long-term industrial applications with the Tadiran TL-5903/S. Engineered with advanced Lithium-Thionyl Chloride ($\text{Li-SOCl}_2$) chemistry, this standard AA-size (ER14505) primary cell delivers an unmatched 3.6V of stable power. Featuring specialized solder tabs for secure circuit board integration, the Tadiran TL-5903/S is built to perform autonomously for up to 20 years in remote environments where traditional batteries fail.
Key Features & Benefits
-
High Energy Density: Delivers a nominal capacity of 2.4Ah in a lightweight, compact form factor (18g).
-
Exceptional Shelf & Operational Life: Boasts a remarkably low self-discharge rate (less than 1% per year), allowing for a 20+ year operating life in low-current applications.
-
Wide Temperature Tolerance: Operates reliably in extreme environments ranging from $-55^\circ\text{C}$ to $+85^\circ\text{C}$.
-
Secure Terminations: The
/Sconfiguration features reliable solder terminals optimized for PCB mounting and custom wire assembly. -
Industrial Reliability: Built with a hermetic glass-to-metal seal and a non-flammable electrolyte to prevent leakage and protect sensitive electronics.
-
Safety Standards: UL Component Recognized (MH 12193) and IEC 60086-4 certified.
