LIHC1013 3.8V 40F Hybrid Capacitor 250000 Cycles -40°C to 65°C 3A Pulse
Scope
This specification describes the characteristics,test methods,and precautions of the ECOLTOLIHC Series (Lithium-ion Hybrid Capacitors).
This product is developed based on ECOLTO internal standards,with reference to:
General Specifications
Rated capacitance at 25±3°C is 40F measured between 3.8V and 2.5V. Nominal voltage is 3.8V. Operating voltage range is 2.5V to 3.8V. Maximum charging voltage is 4.2V. DC internal resistance (DCR) is ≤400mΩ measured at 4.2V with 10ms pulse. AC internal resistance (ACR) is ≤175mΩ measured at 1kHz and 3.6V. Continuous discharge current is 150mA. Pulse discharge current (less than 1 second) reaches 3.0A. Maximum charge current is 300mA. Leakage current is ≤3.0μA after 72 hours at 25°C. Operating temperature range is -40°C to 65°C. Storage temperature range is 10°C to 40°C.
Physical Dimensions
Diameter ΦD is 10mm with +0.5mm maximum. Length L is 13.5±1.5mm. Lead length L1 is 28.5±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 ≤2.5 grams. The cylindrical aluminum shell provides mechanical protection and sealing. The rubber plug prevents short circuits and electrolyte leakage.

Cycle Life Characteristics
Cycle life exceeds 250,000 cycles under standard test conditions (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 percent 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.
