LNX2W682MSEH

The LNX2W682MSEH is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNX series, offering 6.8 mF of capacitance at a 450 V rating. Engineered for industrial power systems, it is suited for inverter circuitry and other high‑ripple, extra‑high‑voltage applications where long operational life and reliable performance are required.

Key electrical and mechanical characteristics include high ripple current capability, a rated operating temperature range of −25 °C to +85 °C, a long endurance of 20,000 hours at +85 °C under rated ripple, and RoHS compliance.

Key Features

• High Capacitance: 6.8 mF (6800 µF) nominal capacitance for bulk energy storage and smoothing in power circuits.
• Extra‑High Voltage Rating: 450 V rated voltage for high‑voltage power applications.
• Screw Terminal Mounting: Robust radial can with screw terminals for secure electrical and mechanical connections in industrial assemblies.
• High Ripple Current: Rated ripple current of 17.3 A at 120 Hz and 24.22 A at 100 kHz to support heavy AC ripple conditions.
• Long Life and Reliability: Endurance specified for 20,000 hours at 85 °C when operated at rated ripple current; designed for extended service in demanding environments.
• Temperature and Tolerance: Operating range −25 °C to +85 °C with capacitance tolerance of ±20% (at 120 Hz, 20 °C).
• Leakage Current Specification: Leakage after 5 minutes is limited to 3√(C·V) μA or 5 mA, whichever is smaller (at 20 °C), enabling predictable leakage behavior for design calculations.
• Flame‑Retardant Electrolyte Available: Flame retardant electrolyte options are available for specified types in the series.
• RoHS Compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Used in inverter circuitry and power supply designs requiring high voltage and sustained ripple handling.
• High‑Voltage Power Modules: Bulk energy storage and smoothing where a 450 V rating and high ripple current capability are needed.
• General Purpose Power Electronics: Suitable for applications calling for long life and reliable performance within the specified temperature range.

Unique Advantages

• Designed for High‑Ripple Environments: Specified ripple current values at both low and high frequencies support reliable operation under heavy AC stress.
• Extended Operational Life: Endurance rating of 20,000 hours at +85 °C under rated ripple current reduces frequency of replacement and maintenance in long‑running systems.
• Robust Mechanical Termination: Screw terminal construction offers secure electrical connections and ease of installation in industrial assemblies.
• Predictable Electrical Behavior: Clear leakage current and tolerance specifications allow accurate margining and thermal/ripple budgeting during design.
• Regulatory Compliance: RoHS conformity and available flame‑retardant electrolyte types support regulatory and safety considerations.
• Compact High‑Energy Footprint: 6800 µF at 450 V in a φ76.2 mm × 190 mm form factor provides significant stored energy in a single radial can.
