LNT2G682MSEH

The LNT2G682MSEH from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNT series designed for high‑voltage, high‑capacitance, general‑purpose power applications. It delivers 6,800 µF capacitance at a 400 V rating with high ripple‑current capability and a long endurance rating at elevated temperature.

This radial can with screw terminals provides robust electrical and mechanical connections for systems that require substantial bulk capacitance, significant ripple handling, and extended life at 105°C.

Key Features

• High Capacitance & Voltage: 6.8 mF (6,800 µF) rated at 400 V for large energy storage in high‑voltage circuits.
• High Ripple Current Handling: Low‑frequency ripple current 27.6 A (120 Hz) and high‑frequency ripple current 38.64 A (100 kHz) to support demanding power filtering and smoothing tasks.
• Endurance at Elevated Temperature: Rated life of 5,000 hours at 105°C when subjected to rated ripple current and DC bias, supporting long service intervals in hot operating environments.
• Leakage Current Specified: Leakage current listed as 4,940 µA, providing a defined baseline for design margining and uptime calculations.
• Screw Terminal Radial Can Package: Robust screw terminal mounting (radial can) for secure, low‑impedance connections in power assemblies.
• Operating Temperature Range: –25°C to +105°C to match the 400 V voltage class within the LNT series temperature specification.
• Tolerance & Polarization: ±20% capacitance tolerance and polarized construction; suitable where polarized electrolytic capacitors are required.
• RoHS Compliant & Packaging: RoHS‑compliant material status and delivered in cardboard packing for handling and storage.
• Physical Size: Case diameter φ76.2 × length 170 mm (L: 17 × D: 7.62 cm) for layout and mechanical planning.

Typical Applications

• General‑purpose power systems — Bulk energy storage and smoothing in high‑voltage power supplies where 400 V rating and large capacitance are needed.
• Industrial power electronics — Filtering and ripple suppression in assemblies that require high ripple‑current capability and durable screw‑terminal connections.
• High‑temperature environments — Applications operating up to 105°C where a specified 5,000‑hour endurance supports reliable long‑term performance.

Unique Advantages

• Large energy reservoir: 6.8 mF at 400 V provides substantial capacitance for energy buffering and smoothing in high‑voltage designs.
• High ripple current capacity: Specified LF/HF ripple ratings (27.6 A at 120 Hz and 38.64 A at 100 kHz) enable effective handling of both low‑ and high‑frequency ripple in power converters.
• Long operating life at 105°C: 5,000‑hour endurance rating under rated ripple and bias reduces maintenance frequency in high‑temperature installations.
• Secure screw‑terminal mounting: Radial can with screw terminals simplifies reliable mechanical and electrical integration in power racks and modules.
• Clear electrical baseline: Specified leakage current and ±20% tolerance provide measurable parameters for margining and system design.
• RoHS compliance: Meets RoHS requirements for environmentally restricted materials handling and procurement.
