LNU2G682MTEH

The LNU2G682MTEH from Nichicon is a screw-terminal aluminum electrolytic capacitor designed for high-voltage industrial power applications. It combines a 6.8 mF capacitance with a 400 V rated voltage in a radial, can-style package with stud bolt mounting.

Built for inverter and regenerative circuits, this capacitor is specified for operation from −40 °C to 105 °C, a 5000-hour load life at 105 °C under rated ripple conditions, and high ripple-current capability at both low and high frequencies—making it suitable for demanding power-supply and motor-drive environments.

Key Features

• Electrical Performance — 6.8 mF capacitance with ±20% tolerance and a 400 V rated voltage; polarized device suitable for DC link and energy-storage roles.
• High Ripple-Current Capability — Rated ripple currents of 19.5 A at 120 Hz and 27.3 A at 10 kHz enable effective handling of both low- and high-frequency ripple loads.
• Temperature and Lifetime — Rated for −40 °C to +105 °C operation and a load life of 5000 hours at 105 °C when subjected to rated ripple and DC bias.
• Rugged Construction & Mounting — Screw terminals and stud bolt mount (radial, can with screw terminals) provide secure electrical and mechanical connections for industrial assemblies.
• Endurance and Charge–Discharge Behavior — Designed to withstand high-speed charge–discharge loading and validated through long-term endurance testing, including charge–discharge cycling up to 50 million cycles under specified test conditions.
• Insulation and Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstanding AC 2500 V for 1 minute without abnormality.
• RoHS Compliance — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: DC link and bulk energy storage for inverter power supplies where high voltage and long life at 105 °C are required.
• Inverter & Motor Drive Circuits: Energy buffering and smoothing in general inverters and AC servomotor drives, including regenerative voltage handling.
• High-Frequency Regeneration: Circuits with high-frequency regenerative voltage or rapid charge–discharge demands that benefit from elevated ripple-current capability.

Unique Advantages

• High-voltage performance in a compact package: 400 V rating and described as smaller-sized than comparable LNT series parts, enabling higher voltage designs with reduced space impact.
• Designed for high-temperature endurance: 5000-hour load life at 105 °C supports reliable operation in thermally demanding installations.
• Strong ripple-current handling: Specified ripple currents at both 120 Hz and 10 kHz allow designers to address a wide range of switching and regenerative conditions.
• Secure mechanical and electrical connections: Screw-terminal construction and stud bolt mounting simplify integration into industrial power assemblies and improve connection robustness.
• Proven charge–discharge resilience: Endurance testing including tens of millions of charge–discharge cycles demonstrates suitability for high-speed cycling applications.
• Compliance-ready: RoHS compliance supports use in designs targeting current environmental directives.
