Key Features

• Capacitance & Voltage: 33,000 µF nominal capacitance at a rated voltage of 80 V, ±20% tolerance for bulk energy storage and smoothing.
• High Ripple-Current Capability: Rated for 9.9 A at 120 Hz and 11.385 A at 100 kHz, enabling effective suppression of AC ripple and transient currents in power rails.
• Endurance & Temperature: Rated lifetime of 2,000 hours at +105°C with DC bias plus rated ripple current; operational temperature range from −40°C to +105°C.
• Low Loss & Leakage: Specified tanδ of 0.3 and leakage current of 4,870 µA, supporting stable performance under continuous bias.
• Package & Mounting: Radial can with screw terminals (φ76.2 × 100L, L: 10 × D: 7.62 cm); screw-terminal construction provides secure, low-impedance connections for high-current applications.
• Compliance & Availability: RoHS compliant and listed as in mass production, suitable for volume deployment.

Typical Applications

• General-purpose power systems: Bulk energy storage and smoothing where high capacitance and high ripple current capability help stabilize DC rails.
• Industrial power electronics: Energy buffering and ripple suppression in equipment that requires robust screw-terminal connections and extended temperature operation.
• DC-link and bus capacitors: High-capacitance, high-ripple handling suited to general-purpose DC-link smoothing and transient absorption tasks.

Unique Advantages

• High energy storage: 33,000 µF at 80 V provides substantial bulk capacitance for smoothing and hold-up without parallel arrays.
• Strong ripple handling: 9.9 A (120 Hz) and 11.385 A (100 kHz) ripple-current ratings reduce thermal stress and extend service life in ripple-intensive applications.
• Screw-terminal robustness: Screw terminals and radial can packaging deliver secure mechanical and electrical connections for high-current installations.
• Wide operating range: −40°C to +105°C operating range with a 2,000-hour endurance at 105°C provides predictable performance in elevated-temperature environments.
• Measured electrical characteristics: Specified tanδ (0.3) and defined leakage current (4,870 µA) allow engineers to design with explicit, verifiable parameters.
• Production readiness: RoHS compliant and in mass production, supporting procurement and supply continuity for production programs.
