LNU2G682MSEJ

The LNU2G682MSEJ is a screw-terminal aluminum electrolytic capacitor offering 6.8 mF capacitance at a 400 V DC rating. Designed for high-voltage, high-ripple environments, it is intended for industrial power electronics such as inverter circuitry and regenerative power applications.

With a 105°C operating rating, a 5000-hour endurance at 105°C under rated ripple current, and RoHS compliance, this radial can with screw terminals provides a robust power-filtering solution for heavy-duty systems that require reliable high-frequency and high-current handling.

Key Features

• Capacitance & Voltage: 6.8 mF nominal capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20°C), suitable for bulk energy storage and DC link filtering.
• High Ripple Current Capability: Low-frequency ripple current of 18.8 A (120 Hz) and high-frequency ripple current of 26.32 A (10 kHz), enabling handling of substantial AC ripple and regenerative currents.
• Thermal & Endurance Performance: Rated for operation from −40°C to +105°C with a specified load life of 5000 hours at 105°C under rated ripple conditions.
• Low Leakage & Loss: Specified leakage current of 4940 µA and a tangent of loss angle (tan δ) of 0.2 for stable electrical behavior under load.
• Robust Mechanical & Mounting Package: Radial can with screw terminals (φ90×105L dimension; nominally L: 10.5 × D: 9.0 cm) for secure bolted connections in panel or chassis-mounted power systems.
• Polarized Construction & Compliance: Polar aluminum electrolytic design with RoHS compliance and mass-production availability from Nichicon.

Typical Applications

• Industrial Inverter Power Supplies: Bulk DC link and smoothing capacitor for inverter stages used in motor drives and industrial power conversion.
• Regenerative Drive Circuits: Energy buffering and ripple handling in high-frequency regenerative voltage systems for AC servomotors and regenerative braking.
• High-Ripple Power Systems: Filtering and peak current support in systems that experience frequent charge–discharge cycles or high-speed switching loads.

Unique Advantages

• High Current Handling: Elevated ripple-current ratings at both low and high frequencies provide margin for designs with significant AC ripple or regenerative energy flow.
• High-Temperature Endurance: 5000-hour life at 105°C under rated ripple current supports long-term reliability in thermally demanding environments.
• Secure Screw-Terminal Connections: Screw-terminal construction enables robust, low-resistance bolted connections for chassis- or bracket-mounted power assemblies.
• Compact High-Voltage Form Factor: φ90×105L radial can provides a high-voltage solution in a manageable footprint for high-voltage power stages.
• Manufacturer Production Readiness: Mass production status from Nichicon assures availability for volume designs and consistent supply.
• Regulatory Compliance: RoHS compliance supports designs targeting regulated markets and reduced-hazard materials.
