5.5V Supercapacitors That Keep Memory Alive – TS12 Series
Advanced energy storage for IoT and memory backup systems
In embedded electronics, ensuring memory retention during power interruptions remains a fundamental challenge. The Suntan TS12 5.5V Coin Type Supercapacitor delivers compact, efficient, and stable gold capacitor energy storage for MCUs, RTCs, and non-volatile memory.
Compared with traditional cells in the ongoing supercapacitor vs battery discussion, TS12 emphasizes low ESR, EDLC technology, and consistent power backup for IoT devices under transient loads — a maintenance-free capacitor approach favored in high reliability designs.
2. Technical Overview
The TS12 offers a rated voltage of 5.5V, a capacitance range of 0.047F–1.0F, and a low-ESR structure for efficient energy delivery. Its compact coin-type form factor provides high volumetric efficiency even in space-limited metering and sensor platforms.
