LNX2W682MSEJ

The LNX2W682MSEJ is an aluminum electrolytic, screw-terminal capacitor from the LNX series designed for extra-high voltage, high-ripple applications. With a rated capacitance of 6800 µF at 450 V and a robust radial can with screw terminals (φ90×150L / 15 cm × 9 cm), it targets industrial power systems that demand sustained performance under heavy ripple and elevated temperature.

Engineered for long life under load, this part provides predictable endurance for industrial power supplies and inverter circuitry where high ripple current and voltage capability are required.

Key Features

• Capacitance & Voltage: 6.8 mF (6800 µF) nominal capacitance with a 450 V rated voltage, suitable for extra-high voltage DC bus applications.
• Screw Terminal Package: Radial can with screw terminals for secure, low-resistance high-current connections; physical size φ90×150L (15 cm × 9 cm).
• High Ripple Capability: Rated ripple current of 17.1 A at 120 Hz and 23.94 A at 100 kHz to support heavy AC superimposed on DC in inverter and power-supply circuits.
• Long-Life Endurance: Designed for 20,000 hours of operation at +85°C when subjected to the rated ripple current, enabling extended service life in continuous-duty systems.
• Operating Temperature Range: Specified for −25°C to +85°C operation, aligning with industrial ambient conditions.
• Tight Electrical Controls: Capacitance tolerance ±20% at 120 Hz, 20°C; leakage current limited to not more than 3√(C·V) µA or 5 mA (after 5 minutes at 20°C), per series specifications.
• Polarized Design: Polar electrolytic capacitor intended for DC applications.
• Compliance & Safety Options: RoHS compliant; series offers flame retardant electrolyte types.

Typical Applications

• Industrial power supplies (inverter circuitry): Suited for DC link and energy storage roles in inverter and industrial power-supply designs that require extra-high voltage and high ripple capability.
• High-ripple, high-voltage systems: Intended for equipment where sustained ripple currents and elevated voltages are present and long operational life is required.
• Long-life industrial installations: Systems requiring predictable endurance over extended duty cycles at elevated temperatures benefit from the 20,000-hour rated life at +85°C.

Unique Advantages

• Extra-high voltage capability: 450 V rating enables use in high-voltage DC bus and inverter-related circuits without the need for series stacking.
• High ripple handling: Measured ripple ratings at both 120 Hz and 100 kHz support a wide range of switching and line-frequency environments.
• Extended in-service life: 20,000 hours at +85°C under rated ripple current reduces replacement frequency and supports continuous-operation applications.
• Robust screw-terminal connectivity: Screw terminals and a radial can package provide reliable, low-impedance connections for high-current paths.
• Controlled electrical characteristics: Defined capacitance tolerance and leakage current limits allow predictable filtering and energy-storage performance.
• Regulatory compliance and safety options: RoHS compliance and availability of flame retardant electrolyte types address environmental and safety considerations.
