LNX2L682MSEJ

The LNX2L682MSEJ is an aluminum electrolytic capacitor in a screw‑terminal, radial can package designed for extra‑high voltage and high‑ripple current applications. It provides 6800 µF capacitance at a 550 V rating in a φ90 × 220L form factor, targeting industrial power electronics where robust energy buffering and ripple handling are required.

Part of Nichicon’s LNX series, this device emphasizes high ripple capability, polarized construction, and engineered reliability for sustained operation up to +85°C.

Key Features

• Capacitance & Voltage: 6.8 mF (6800 µF) nominal capacitance at a 550 V rated voltage suitable for extra‑high voltage DC bus and energy storage applications.
• Screw Terminal Mounting: Radial can with screw terminals (bolt nominal M5 for φ90) for secure, low‑impedance power connections and straightforward installation in power racks and assemblies.
• High Ripple Current: Rated ripple current of 19.5 A at 120 Hz and 27.3 A at 100 kHz to support demanding inverter and power conversion duty cycles.
• Operating Range & Polarization: Polarized capacitor rated for operation from −25°C to +85°C with ±20% capacitance tolerance at 120 Hz, 20°C.
• Endurance & Lifetime: Series endurance is specified for long life; for parts rated 500 V and 550 V (including this part) the specified endurance under DC bias plus rated ripple is 5000 hours at 85°C.
• Leakage Current Specification: After 5 minutes’ application of rated voltage, leakage current is limited to 3√(C·V) µA or 5 mA, whichever is smaller, providing predictable post‑assembly behavior.
• RoHS Compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk energy storage and DC bus smoothing in industrial power supplies where high voltage and ripple tolerance are required.
• Inverter Circuits: DC link and smoothing for motor drives and inverter stages that demand high ripple current handling and stable capacitance under load.
• High‑Voltage Power Conversion: Energy buffering and decoupling in power conversion systems operating at extra‑high voltages up to 550 V.

Unique Advantages

• Extra‑High Voltage Capability: 550 V rating enables use in power systems and DC buses that require elevated voltage margins.
• High Ripple Endurance: Substantial ripple current ratings at both low and high frequencies reduce temperature rise and extend service life in ripple‑intensive circuits.
• Screw‑Terminal Robustness: Screw terminals provide reliable mechanical and electrical connections for high‑current installations and ease of assembly.
• Specified Endurance for 550 V Parts: Clear endurance specification of 5000 hours at 85°C under DC bias plus rated ripple current informs lifetime planning for high‑voltage designs.
• Predictable Leakage Behavior: Defined leakage current limit after voltage application supports predictable system startup and leakage budgeting.
• Regulatory Compliance: RoHS compliance supports use in designs requiring restricted‑substance conformance.
