Super Capacitor 2.7V 500F

Super Capacitor 2.7V 500F delivers a powerful, high-capacity energy storage solution, bridging the gap between conventional electrolytic capacitors and rechargeable batteries. This single-cell ultracapacitor stores a massive 500 Farads of charge at 2.7 volts, consequently providing tremendous power density for instantaneous energy delivery. Since it relies on electrostatic charge rather than a chemical reaction, it supports over a million charge/discharge cycles and offers an exceptional lifespan. Therefore, system designers frequently choose this super capacitor for applications demanding fast charge times, high peak currents, and long-term reliability.

Key Features:

• Ultra-High Capacitance: The 500 F rating stores significant energy, perfect for high-power demands and short-term backup.
• Rapid Charge/Discharge: Allows for quick energy cycling, hence charging and discharging much faster than traditional batteries.
• Extended Cycle Life: Offers a cycle life of ≥ 500,000 cycles, providing superior longevity compared to chemical storage devices.
• Low ESR: A low Equivalent Series Resistance (ESR) of typically ≤ 10 mΩ minimizes internal power loss and maximizes peak power output.
• Wide Temperature Range: Operates reliably across a broad temperature range, typically from −40°C to +65°C.

Technical Specifications:

• Nominal Capacitance: 500 F (Farads)
• Rated DC Voltage (V_R): 2.7 V
• Capacitance Tolerance: −10% / +20% (Typical)
• Equivalent Series Resistance (ESR): ≤ 10 mΩ (Typical, measured at 1 kHz)
• Surge Voltage: 2.85 V max (Non-continuous)
• Leakage Current: ≤ 1.0 mA (After 72 hours)
• Operating Temperature Range: −40°C to +65°C

Mechanical Specifications:

• Case Type: Cylindrical Metal Can (Black/Blue)
• Terminal Type: Snap-in or Solder Lug (Varies by specific model/manufacturer)
• Material: Durable metal foil construction with clear polarity markings.

Dimensions:

• Body Diameter (ΦD): ≈ 35 mm
• Body Height (L): ≈ 60 mm
• Lead Spacing (P): ≈ 10 mm (For snap-in/radial versions)
• Weight: ≈ 60 g (Extremely lightweight for its capacity)

Pinout and Wiring:

• Positive Terminal (+): Connect this terminal to the positive voltage source.
• Negative Terminal (−): Connect the negative terminal to the system ground or the lower voltage line.
• Polarity Warning: Always observe correct polarity during installation. Otherwise, reverse voltage application will permanently damage the super capacitor.
• Series Connection: Connect multiple units in series to achieve higher operating voltages (e.g., six units create a 16.2V system); however, you must use a voltage balancing circuit in series configurations.
