The LNU2G682MTEJ is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNU series, rated 6800 µF at 400 V and specified for operation to 105°C. It is a stud‑bolt, radial can with screw terminals, designed for general purpose and industrial power applications where high voltage handling and high ripple tolerance are required.

Engineered for continuous operation under demanding thermal and electrical load, this capacitor offers a 5000‑hour load life at 105°C and is RoHS compliant, making it suitable for mass‑production deployment in power conversion systems.

Key Features

• Capacitance & Voltage — 6800 µF nominal capacitance with a rated voltage of 400 V and ±20% tolerance (120 Hz, 20°C).
• High temperature rating — Rated for operation from −40°C to +105°C and endurance specified for 5000 hours at 105°C under rated ripple conditions.
• Screw terminal / Stud bolt mount — Radial can with screw terminals and stud bolt mounting for secure, low‑impedance power connections in high‑current systems.
• Ripple current capability — Specified ripple current of 18.8 A at 120 Hz and 26.32 A at 10 kHz, supporting both low‑ and high‑frequency ripple conditions.
• Compact high‑voltage form factor — φ90 × 105 mm overall dimensions (L: 10.5 cm × D: 9.0 cm) offering a high‑voltage solution in a smaller footprint compared with larger series options.
• Durability and charge‑discharge endurance — Designed to withstand repeated charge/discharge cycles (endurance defined in series data) and meet leakage, tan δ, and capacitance stability requirements after endurance testing.
• Environmental compliance — RoHS compliant.

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing for inverter and converter front ends in industrial power supplies where 400 V class capacitors are required.
• AC servo and motor drives — Support for high‑frequency regenerative voltage and rapid charge‑discharge cycles in servo amplifiers and drive inverters.
• General inverter systems — DC link and energy buffering in inverters used for industrial motors, power conversion, and renewable energy inverters.
• High ripple environments — Applications requiring elevated ripple current handling at both low and high frequencies, leveraging specified 120 Hz and 10 kHz ripple ratings.

Unique Advantages

• High voltage capability: 400 V rated voltage provides headroom for 400 V class DC link and power conversion designs.
• High temperature endurance: 105°C maximum operating temperature and a 5000‑hour rated life at 105°C help ensure long service life in thermally demanding installations.
• Robust mechanical connection: Screw terminal and stud‑bolt mounting deliver secure, low‑resistance electrical connections for high current paths.
• Wide ripple handling: Specified ripple current values at 120 Hz and 10 kHz allow designers to dimension for both mains‑frequency and high‑frequency switching environments.
• Series‑level reliability features: Endurance, shelf‑life, and charge‑discharge performance are specified in the LNU series data to maintain capacitance, tan δ, and leakage current within limits after stress tests.
• RoHS compliance: Meets RoHS requirements for restricted substances, simplifying environmental compliance for finished equipment.
