LNX2W682MSEJBB

The LNX2W682MSEJBB is an aluminum electrolytic, screw-terminal capacitor engineered for industrial power applications. Its screw-terminal radial can design and high rated voltage make it suitable for use in industrial power supplies and inverter circuitry where large capacitance and robust mounting are required.

Designed for extra-high voltage operation and sustained ripple environments, this part delivers long operational life and measured ripple performance while meeting RoHS environmental requirements.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance with a rated voltage of 450 V and tolerance of ±20% at 120 Hz, 20°C.
• Screw-Terminal Package — Radial can with screw terminals for secure, low-resistance connections in industrial enclosures; physical size φ90 × 150L (L: 15 × D: 9 cm).
• High Ripple Capability — Rated ripple current of 17.1 A at 120 Hz and 23.94 A at 100 kHz, supporting heavy AC ripple and high-frequency decoupling in power conversion circuits.
• Extended Lifetime — Endurance specified for 20,000 hours at +85°C under rated ripple current conditions, supporting long-term reliability in continuous-duty systems.
• Operating Temperature Range — Specified for use from −25°C to +85°C.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20°C).
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863); flame-retardant electrolyte option is available in the series.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and smoothing in industrial rectifiers and supplies, including inverter front-ends.
• Inverter Circuitry — DC-link and decoupling duties where high ripple current and extra-high voltage rating are required for reliable operation.
• High-Voltage Power Systems — Energy buffering and filtering in systems that demand large capacitance at elevated voltages and extended lifetime.

Unique Advantages

• High Energy Density: 6.8 mF at 450 V provides substantial charge storage for DC-link and smoothing functions, reducing the number of parallel components required.
• Robust Ripple Handling: Measured ripple ratings at both low and high frequencies (17.1 A at 120 Hz, 23.94 A at 100 kHz) support demanding AC and switching environments.
• Long Service Life: 20,000-hour endurance at +85°C under rated ripple extends maintenance intervals and supports continuous industrial operation.
• Secure Mechanical Termination: Screw-terminal mounting enables repeatable, low-resistance electrical connections and simplifies installation in rugged equipment.
• Standards-Conscious Design: RoHS compliance and the availability of flame-retardant electrolyte types facilitate regulatory and safety planning in product designs.
