Key Features

• Capacitance & Voltage: 3.3 mF (3300 µF) rated at 500 V for bulk energy storage in high-voltage power stages.
• Screw-terminal Package: Radial can with screw terminals for secure, low-inductance connections in power assemblies and easy serviceability.
• High Ripple Current: Handles 17.8 A at 120 Hz and 24.92 A at 100 kHz, supporting high-frequency inverter and regenerative loads.
• Temperature Range & Lifetime: Operates from −40°C to +85°C with a rated load life of 5,000 hours at 85°C under ripple current conditions.
• Compact Mechanical Size: φ76.2 × 105L (L: 10.5 × D: 7.62 cm) provides smaller footprint and higher ripple capability compared to LNX/LNK series.
• Robust Endurance: Designed to withstand 50 million charge–discharge cycles (ΔV = rated × 0.3, 3 Hz) while meeting capacitance, tan δ and leakage current limits.
• Leakage & Insulation Characteristics: Leakage current after 5 minutes is ≤ 3√V µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Safety Proof Voltage: Withstands AC 2500 V for 1 minute between terminal and bracket with no abnormality.
• Polarized Construction: Polarized electrolytic design appropriate for DC bus and bulk energy applications.
• RoHS Compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters: Bulk DC-link energy storage for inverter power stages where high voltage and high ripple current capability are required.
• AC Servomotor Drives: Regenerative and high-frequency voltage handling in servo amplifiers and motor control systems.
• Power Supplies for Industrial Equipment: High-voltage smoothing and surge absorption in industrial power supplies and converter modules.
• High-Speed Charge–Discharge Systems: Applications requiring frequent charge–discharge cycling, supported by the capacitor's 50 million cycle endurance specification.

Unique Advantages

• High Ripple Handling: Measured ripple currents of 17.8 A (120 Hz) and 24.92 A (100 kHz) enable reliable operation in demanding high-frequency power stages.
• Long Operational Life: 5,000 hours at 85°C under rated ripple conditions supports extended service intervals in industrial deployments.
• Compact High-Voltage Solution: φ76.2 × 105L package delivers high capacitance at 500 V in a footprint optimized relative to comparable series.
• Durable Under Repetitive Stress: Endurance validated to 50 million charge–discharge cycles reduces risk of premature degradation in cyclic applications.
• Robust Dielectric and Insulation Performance: Low leakage current limits and insulation resistance >100 MΩ at DC 500 V help maintain performance over time.
• Regulatory Compliance: RoHS conformity supports deployment in regions and projects that require restricted-substance compliance.
