Key Features

• High Capacitance / Voltage: 12,000 µF at 350 V delivers bulk energy storage for power conversion, smoothing and hold-up in industrial power systems.
• Screw Terminal Mounting: Radial, can package with screw terminals for secure mechanical and electrical connections in heavy-current installations.
• Long Endurance: Rated for 20,000 hours of standard ripple current at +85°C, supporting long-term operation under rated conditions.
• High Ripple Current: Rated ripple current of 24.8 A at 120 Hz and 34.72 A at 100 kHz, enabling reliable performance under high AC stress.
• Wide Operating Range: Operation from −25 °C to +85 °C with an impedance ratio Z(−25 °C)/Z(+20 °C) of up to 8 for stable low-temperature behavior.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller (measured at 20 °C).
• Flame-Retardant Electrolyte Option: Series offers flame-retardant electrolyte types where required for enhanced safety.
• RoHS Compliant: Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Dimensions: Nominal size L: 15 cm × D: 9 cm with a maximum seated height of 5.906 inch, supporting integration into rack- and chassis-mounted power assemblies.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and smoothing for converters and rectifiers in industrial supply systems.
• Inverter Circuitry: DC link and buffering in inverter stages where high ripple current and extra-high voltage capability are required.
• High-Voltage, High-Ripple Environments: Power electronics demanding sustained ripple handling and long operational life at elevated temperatures.

Unique Advantages

• Long Operational Life: 20,000-hour endurance at +85 °C under rated ripple current reduces maintenance and replacement frequency in continuous-duty systems.
• High Ripple Capability: Specified ripple currents at both 120 Hz and 100 kHz provide measurable performance for designers balancing low- and high-frequency ripple stress.
• Secure, High-Current Termination: Screw-terminal construction simplifies connection and accommodates robust current paths for industrial installations.
• Clear Leakage Specification: Leakage current limit (3√CV µA or 5 mA) gives predictable startup and hold characteristics for power designs.
• Safety & Compliance Options: Availability of flame-retardant electrolyte types and RoHS compliance support regulatory and safety considerations.
