LNC2G682MTEH

The LNC2G682MTEH from Nichicon is a screw‑terminal, stud‑bolt mount aluminum electrolytic capacitor specified at 6.8 mF (6800 µF) and 400 V. It is part of the LNC series designed for high‑ripple, high‑frequency charge/discharge environments where sustained performance and lifetime at elevated temperatures are required.

This capacitor targets industrial power electronics applications such as inverter circuitry and regenerative voltage circuits, delivering high ripple current capability, a tested 5000‑hour endurance at 85°C, and RoHS compliance for regulated designs.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 400 V with ±20% tolerance (120 Hz, 20°C), supporting bulk energy storage and DC link applications.
• High Ripple Current — Designed for heavy ripple loading: 23.1 A at 120 Hz (low frequency) and 32.34 A at 100 kHz (high frequency), enabling use in inverter and regenerative circuits.
• Thermal & Endurance — Rated operating temperature range −40°C to +85°C with a specified lifetime of 5000 hours at 85°C under rated ripple conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) = 0.2 measured at 20°C, 120 Hz, for predictable ESR behavior in AC and switching applications.
• Leakage Current — Specified leakage current of 4940 µA after standard voltage application, useful for design consideration in power‑supply hold‑up and standby scenarios.
• Mechanical & Mounting — Screw‑terminal, stud bolt mount package (radial can with screw terminals) sized φ76.2 × 120 mm (D × L) for robust panel or bracket installation.
• Environmental Compliance & Packaging — RoHS compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• Industrial Inverters — Bulk DC link and smoothing capacitor for inverter power stages where high ripple current and long life at 85°C are required.
• AC Servomotor Regeneration — Energy storage for regenerative braking and high‑frequency regenerative voltage circuits in motor drive systems.
• High‑Frequency Power Supplies — Filter and decoupling capacitor for switching supplies that demand low loss and strong charge/discharge tolerance at elevated frequencies.

Unique Advantages

• High ripple capacity: 23.1 A (120 Hz) and 32.34 A (100 kHz) ratings help manage thermal stress and extend system runtime under heavy switching loads.
• Long operational life at elevated temperature: 5000 hours endurance at 85°C under rated ripple current supports reliable service in industrial environments.
• Robust mounting and termination: Screw‑terminal stud bolt mount enables secure mechanical and electrical connections for high‑current applications.
• Clear electrical characterization: Specified tan δ (0.2 at 20°C, 120 Hz) and defined leakage current enable predictable ESR/impedance behavior during design and validation.
• Regulatory readiness: RoHS compliance facilitates use in regulated assemblies without additional component screening.
