LNX2H682MSEJBB

The LNX2H682MSEJBB is a screw-terminal aluminum electrolytic capacitor offering 6.8 mF capacitance at a 500 V rating in a radial can package with screw terminals. It is engineered for high-ripple, extra-high-voltage applications commonly found in industrial power supplies and inverter circuitry.

Designed for long operational life under rated ripple conditions, this capacitor supports heavy ripple currents and sustained operation up to +85°C, making it suitable for demanding power-conversion environments that require reliable DC-bus smoothing and energy buffering.

Key Features

• Capacitance and Voltage: 6.8 mF (6800 µF) nominal capacitance with a 500 V rated voltage for high-voltage DC applications.
• High ripple current capability: Rated ripple current of 18.5 A at 120 Hz and 25.9 A at 100 kHz to support heavy AC ripple on the DC bus.
• Long-life endurance: Endurance rating of 5000 hours at +85°C under rated ripple current for sustained, reliable service in high-stress power circuits.
• Temperature range: Operates from −25°C to +85°C, enabling use across typical industrial ambient conditions.
• Screw terminal mounting: Radial can with screw terminals for secure, low-inductance, high-current connections in power assemblies.
• Capacitance tolerance: ±20% (at 120 Hz, 20°C), allowing predictable filtering and energy storage sizing.
• RoHS compliant: Meets RoHS requirements and offers a flame-retardant electrolyte type as an available option.
• Physical size: Compact high-energy package with nominal dimensions L: 17 cm × D: 9 cm for integration into power racks and enclosures.

Typical Applications

• Industrial power supplies: DC-bus smoothing and energy storage in high-voltage industrial supplies and power racks.
• Inverter circuitry: Bulk and smoothing capacitor for inverter DC-link circuits where high ripple current handling is required.
• High-voltage power conversion: Energy buffering and ripple attenuation for converters and choppers operating at extra-high voltages.

Unique Advantages

• High-voltage capability: 500 V rating enables use in extra-high-voltage circuits without series stacking.
• High ripple handling: Substantial ripple current ratings at both low and high frequencies reduce thermal stress and support tighter DC regulation.
• Durable under elevated temperature: 5000-hour endurance at +85°C under rated ripple conditions provides predictable service life in hot environments.
• Robust screw-terminal connection: Facilitates secure, low-resistance installation for high-current bus connections in power assemblies.
• Regulatory and safety options: RoHS compliance and availability of a flame-retardant electrolyte option support regulatory requirements and improved safety considerations.
