AW-PZ-2R7-108

The AW-PZ-2R7-108 is rated for maximum continuous current of 0.6A at 25°C, limited by thermal considerations of the thin package. At this current, power dissipation in the ESR is approximately 29mW (0.6² × 0.08), resulting in minimal temperature rise. For pulse applications, currents up to 3A are permissible for durations up to 1 second. The higher current capability compared to the 5F model is due to the lower 80mΩ ESR. For applications requiring sustained currents above 0.6A, parallel connection of multiple cells or selecting a higher-capacitance model is recommended. Current capability decreases at elevated temperatures - approximately 0.5A at 45°C and 0.35A at 65°C. Always verify actual operating temperature in your application.

For continuous currents above 0.6A, parallel multiple cells or select the 30F model with lower ESR.

The AW-PZ-2R7-108 stores approximately 0.01 Wh of energy (E = 0.5 × 10F × 2.7V² = 36.45 Joules). Backup time depends on load current and allowable voltage drop. For a constant 50mA load from 2.7V to 1.35V (50% voltage drop), backup time is approximately 10F × 1.35V / 0.05A = 270 seconds or 4.5 minutes. At 100mA load, backup time reduces to approximately 2.25 minutes. For burst applications typical in IoT devices (e.g., 500mA for 1 second every minute), the cell can support thousands of transmission cycles. The actual usable energy should be calculated using E_usable = 0.5 × C × (V_max² - V_min²) where V_min is your system's minimum operating voltage. For precise calculations, contact our FAE team with your specific load profile.

The AW-PZ-2R7-108 should be charged using a current-limited source with the following parameters: Maximum charge current: 1A (0.1C rate) for standard charging, up to 3A for fast charging with reduced cycle life. Charge voltage: 2.7V maximum, with 2.5V recommended for extended cycle life. Charge profile: Constant current (CC) until reaching charge voltage, then constant voltage (CV) until current tapers to 0.01C. Charge time from fully discharged: approximately 15 seconds at 3A fast charge, or 45 seconds at 1A standard charge to reach 90% capacity. Simple resistor-limited charging can be used for low-cost applications, though this is less efficient. Always include overvoltage protection (2.85V absolute maximum) to prevent cell damage. The cell can accept charge at temperatures from -40°C to +65°C, though charging at elevated temperatures reduces cycle life.

Use a dedicated supercapacitor charger IC for optimal performance. Contact our FAE team for recommended charger circuits and ICs.

The AW-PZ-2R7-108 is suitable for outdoor applications within its specified operating temperature range of -40°C to +65°C. The aluminum laminate packaging is sealed against moisture and dust when properly handled. For outdoor installations, additional environmental protection is recommended: enclosure with IP65 rating or better, UV protection if exposed to direct sunlight, and protection from physical damage. The wide temperature range accommodates most outdoor environments, though performance varies with temperature. At low temperatures (-40°C), ESR increases to approximately 300mΩ, limiting high-current capability. At high temperatures (+65°C), leakage current increases and cycle life is reduced. For extreme outdoor applications, consider thermal management or selecting cells specifically rated for extended temperature ranges. The cell is not rated for submersion or high-humidity condensation environments without additional protection.

For outdoor applications, ensure adequate enclosure protection. Contact our FAE team for environmental sealing recommendations.

The AW-PZ-2R7-108 has a shelf life of 2 years when stored in original unopened packaging at temperatures between -20°C and +35°C and relative humidity below 60%. After 2 years, the cell may require additional charging cycles to achieve full performance. Storage at elevated temperatures accelerates aging and should be avoided. The cell is shipped at approximately 50% state of charge for safety and longevity. During storage, some voltage drop due to self-discharge is normal - the cell may drop to 0.5V or lower over extended storage periods. This does not damage the cell; normal capacity is restored after charging. For long-term storage beyond 2 years, cells should be charged to 2.0-2.5V and stored in a cool, dry environment. Always check cell voltage before use after extended storage and charge if below 0.5V.

Rotate inventory to use cells within 2 years of receipt. Contact us for long-term storage recommendations if needed.

Visual inspection can identify most handling damage to the AW-PZ-2R7-108. Check for: punctures or tears in the aluminum laminate packaging, swelling or bulging of the cell body, electrolyte leakage (oily residue), bent or damaged tabs, and discoloration of the packaging. Electrical testing should measure: capacitance within ±20% of rated 10F, ESR less than 80mΩ, and leakage current less than 0.03mA at 72 hours. Significant deviation from these parameters may indicate damage. A damaged cell should not be used - dispose of according to local regulations. If electrolyte contacts skin, wash immediately with water. The cell contains organic electrolyte that can be irritating but is not highly toxic. Damaged cells may vent gas or heat if charged - never charge a visibly damaged cell.

Perform incoming inspection on all cells. Reject any cells showing visible damage or out-of-spec electrical parameters.
