• Screw Terminal Mounting — Radial can with screw terminals for secure, low-impedance connections in industrial power assemblies.
• High Ripple Current — Rated ripple current of 21.3 A at 120 Hz and 29.82 A at 100 kHz, enabling robust handling of switching and inverter-derived ripple.
• Long Life at Elevated Temperature — Qualified for 20,000 hours at +85°C under rated ripple current, supporting long-term reliability in thermal-stressed power systems.
• Operating Temperature Range — Specified for operation from −25 °C to +85 °C to accommodate industrial ambient conditions.
• Capacitance Tolerance & Polarization — ±20% tolerance at 120 Hz, 20 °C; polarized design for conventional electrolytic applications.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current not more than 3√CV (µA) or 5 mA, whichever is smaller (data from series specification).
• Safety & Environmental — Flame-retardant electrolyte available for select types; RoHS-compliant (2011/65/EU, (EU)2015/863).
• Physical Size — Package dimension listed as L: 15 × D: 9 cm in a radial can format with screw terminals for secure mounting.

Typical Applications

• Industrial Power Supplies and Inverters — Serves as DC-link and bulk capacitance in inverter circuitry and industrial power-conversion equipment where high ripple current and voltage are required.
• High-Voltage Power Conversion — Suitable for extra-high-voltage applications within the series-rated voltage range, providing energy storage and ripple filtering.
• General-Purpose Industrial Systems — Used in general-purpose industrial designs that require polarized, high-capacitance, long-life electrolytic capacitors with screw-terminal connections.

Unique Advantages

• High Ripple Endurance: Rated ripple current figures (21.3 A at 120 Hz, 29.82 A at 100 kHz) enable reliable operation in switch-mode and inverter environments.
• Extended Operational Life: 20,000-hour life at +85 °C under rated ripple current supports reduced maintenance and longer service intervals in industrial equipment.
• Robust Mechanical Connection: Screw-terminal radial can package provides a secure, low-resistance electrical connection for heavy-current applications.
• Series-Level Safety Options: Availability of flame-retardant electrolyte types supports designs requiring enhanced flammability performance.
• Regulatory Compliance: RoHS compliant to 2011/65/EU and (EU)2015/863, aiding regulatory alignment for industrial deployments.
• Clear Leakage Specification: Defined leakage-current limit after voltage application (3√CV µA or 5 mA) supports predictable conditioning and commissioning procedures.
