LIHC1313 70F 3.8V LIHC 12.5x13.5mm 600mΩ DCR 2.5A Pulse 260mA Continuous

General Specifications
Rated capacitance at 25±3°C is 70F, measured between 3.8V and 2.5V. Nominal voltage is 3.8V. Operating voltage spans 2.5V to 3.8V. Maximum charging voltage is 4.2V. DCR is ≤600mΩ at 4.2V with 10ms pulse. ACR is ≤175mΩ at 1kHz and 3.6V. Continuous discharge current is 260mA. Pulse discharge current (<1s) is 2.5A. Maximum charge current is 500mA. Leakage current is ≤4.0μA after 72h at 25°C. Operating temperature is -40°C to 65°C. Storage temperature is 10°C to 40°C.

Physical Dimensions
Diameter ΦD is 12.5mm with +0.5mm maximum. Length L is 13.5±1.5mm. Lead length L1 is 29±1.0mm and L2 is 23±1.0mm. Lead diameter Φd is 0.6±0.1mm. Lead pitch P is 5±0.5mm. Weight is ≤3.5 grams. The cylindrical aluminum shell provides mechanical protection and sealing. The rubber plug prevents short circuits and electrolyte leakage. This 12.5mm diameter body offers a wider footprint with a shorter height compared to the 10mm diameter series.

Cycle Life Characteristics
Cycle life exceeds 250,000 cycles under 10C charge/discharge between 3.7V and 3.1V at room temperature. After 250,000 cycles, capacitance retention is at least 70 percent of initial value and internal resistance remains within 4 times the initial specified value.

Temperature Performance
At -20°C, capacitance retention is ≥70% of initial value and internal resistance ≤10 times initial specified value. At +65°C, capacitance change stays within ±10 percent of initial value and internal resistance remains within initial limits. High temperature and high humidity storage (60±3°C, 90±3% RH for 1000 hours) results in capacitance ≥70% and internal resistance ≤2 times initial value. High temperature float test at 65°C and 3.8V for 1000 hours maintains capacitance ≥70% and resistance ≤4 times initial value.

Safety and Quality
The product meets general safety requirements with no explosion and no fire under overcharge, short circuit, thermal exposure, and mechanical stress tests. It complies with IEC 62831 and IEC 62391 standards.

Applications
This LIHC is ideal for IoT devices and smart meters requiring intermittent data transmission and long standby life. It powers wireless communication modules (RF/GPS) for burst transmissions. It serves as a backup power source for memory retention and real time clocks. It provides energy buffering and peak power support for industrial sensors, actuators, and controllers. The wider 12.5mm diameter suits applications where height is constrained but board space allows a larger footprint.
