LNX2W682MSEHBB

The LNX2W682MSEHBB is an aluminum electrolytic capacitor in a screw-terminal can designed for extra-high voltage, high-ripple applications. It delivers 6.8 mF capacitance at a 450 V rating in a φ76.2 × 190 mm package, targeting industrial power electronics such as inverter circuitry and industrial power supplies.

Built for long-life operation under rated ripple conditions, this Nichicon LNX series part emphasizes high ripple capability, robust screw-terminal connections and long endurance at elevated temperature for reliable service in heavy-duty power systems.

Key Features

• Capacitance & Voltage: 6.8 mF (6800 µF) nominal capacitance with a 450 V rated voltage and ±20% tolerance, providing bulk energy storage for high-voltage power rails.
• High ripple capability: Rated ripple currents of 17.3 A at 120 Hz and 24.22 A at 100 kHz support heavy AC ripple stress in power conversion and inverter stages.
• Long endurance at elevated temperature: Specified for 20,000 hours of operation at +85°C under rated ripple current, offering extended service life for continuous-duty industrial use.
• Screw terminal package: Radial can with screw terminals for secure, low-inductance connections; nominal bolt diameter M5 for the φ76.2 size.
• Operating range: Specified operating temperature range of −25°C to +85°C to match typical industrial ambient conditions.
• Leakage and loss characterization: Leakage current specified as ≤ 3√(C·V) µA or 5 mA (whichever is smaller) after 5 minutes at 20°C; tan δ measurement referenced at 120 Hz, 20°C per datasheet.
• Safety and materials: Flame-retardant electrolyte available; RoHS compliant (2011/65/EU, (EU)2015/863).
• Form factor: φ76.2 × 190 mm (L: 190 mm × D: 76.2 mm), suitable where large capacitance and high voltage must be accommodated in a screw-terminal can.

Typical Applications

• Industrial power supplies: Bulk energy storage and smoothing for high-voltage industrial supply rails where sustained ripple capability and reliability are required.
• Inverter circuitry: DC-link and filtering applications in inverter stages that demand extra-high voltage handling and high ripple current endurance.
• Power conversion systems: Energy buffering and decoupling in converters and chokes where durable long-life capacitors reduce maintenance intervals.

Unique Advantages

• Extra-high voltage capability: 450 V rating enables use in high-voltage DC-link and industrial power topologies without series stacking.
• High ripple handling: Specified ripple currents at both low and high frequencies (17.3 A at 120 Hz, 24.22 A at 100 kHz) reduce overheating and extend system reliability under AC stress.
• Extended operational life: 20,000-hour endurance at +85°C under rated ripple current minimizes replacement frequency in continuous-duty installations.
• Robust mechanical termination: Screw-terminal radial can and M5 bolt accommodation provide secure electrical and mechanical connections for industrial assemblies.
• Regulatory and safety consideration: RoHS compliance and availability of flame-retardant electrolyte help meet environmental and safety requirements.
• Measurable leakage and loss limits: Defined leakage current and tan δ measurements per datasheet allow predictable performance characterization during design and qualification.
