Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) rated at 350 V for DC link and energy-buffer applications.
• Tolerance & Polarity: ±20% capacitance tolerance at 120 Hz, polarized type suitable for polarized DC circuits.
• High Ripple Current: Rated ripple current of 10.3 A at 120 Hz and 14.42 A at 100 kHz, supporting heavy ripple loading and high-frequency operation.
• Long Load Life: Designed for 5000 hours of load life at 85°C under rated ripple conditions, with specified endurance characteristics after the test period.
• Thermal and Environmental Range: Operating temperature range −40°C to +85°C; compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Mechanical & Mounting: Stud bolt (screw terminal) radial can package for robust electrical and mechanical connections; physical size L: 7.5 × D: 5.1 cm.
• Endurance for Charge–Discharge: Specified to survive 50 million charge–discharge cycles at room temperature under defined conditions, supporting high-speed cycling applications.
• Electrical Safety Characteristics: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute between terminal and bracket without abnormality.

Typical Applications

• Industrial Inverter Power Supplies: DC link and energy storage in inverter modules where sustained ripple handling and long load life are required.
• AC Servomotor Drives: Regenerative and high-frequency voltage buffering for servo inverter stages and motor drive electronics.
• High-Frequency Charge–Discharge Systems: Circuits requiring rapid charge–discharge cycles and robust endurance under repeated switching events.
• General Purpose Industrial Power Electronics: Bulk filtering and energy buffering in industrial power stacks and converter assemblies.

Unique Advantages

• High ripple-current capability: Explicit ripple ratings at both 120 Hz and 100 kHz (10.3 A and 14.42 A) allow designers to specify the capacitor for demanding ripple and high-frequency loads.
• Proven long-term reliability: Load life rating of 5000 hours at 85°C under rated ripple conditions provides a quantifiable metric for lifecycle planning.
• Compact, screw-terminal packaging: Stud bolt mount radial can with screw terminals simplifies mechanical mounting and high-current connections in power assemblies.
• High-frequency and regenerative readiness: Series design notes specifically call out suitability for high-frequency regenerative voltage and high-speed charge–discharge behavior.
• Robust electrical isolation: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V proof between terminal and bracket improve system safety margins.
• RoHS compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863) for regulatory and environmental requirements.
