LNC2V682MSEGBB

The LNC2V682MSEGBB is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNC series, rated 6.8 mF (6800 µF) at 350 V. It is a radial can with screw terminals designed for industrial power applications where high ripple handling and reliable DC link performance are required.

Engineered for inverter circuitry and industrial power supplies, this capacitor delivers high ripple-current capability and endurance for high-frequency regenerative and rapid charge–discharge conditions while complying with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance with a rated voltage of 350 V and ±20% tolerance at 120 Hz, 20°C.
• Mounting & Package — Screw terminal radial can package for robust electrical and mechanical connections in industrial assemblies; case dimensions φ63.5 × 135 mm (L: 13.5 × D: 6.35 cm).
• High Ripple Current — Rated ripple current of 20.3 A at 120 Hz and 28.42 A at 100 kHz to support high-frequency inverter and regenerative circuits.
• Operating Temperature & Life — Designed for –40°C to +85°C operation with a load life of 5000 hours at 85°C under rated ripple conditions.
• Charge–Discharge Endurance — Qualified for charge–discharge endurance (50 million cycles at ΔV = rated voltage × 0.3, 3 Hz) per series specifications.
• Leakage & Insulation — Leakage current specified as not more than 3√V µA or 5 mA (whichever is smaller) after 5 minutes at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket. Voltage proof: AC 2500 V, 1 minute between terminal and bracket.
• Series Advantages — Part of the LNC family, offering a smaller size and higher ripple capability compared with earlier LNX/LNK series designs for space-constrained industrial power systems.

Typical Applications

• Industrial Inverters — DC link and smoothing in inverter power stages where high ripple current and long endurance at elevated temperatures are required.
• AC Servomotor Regeneration — Handling high-frequency regenerative voltages in servo drives and motion-control systems.
• Industrial Power Supplies — Bulk energy storage and ripple filtering in power supplies for motor drives and factory automation equipment.
• High-Speed Charge–Discharge Systems — Applications that demand rapid charge–discharge cycling, supported by the LNC series' endurance characteristics.

Unique Advantages

• High ripple-current capability: Supports 20.3 A at 120 Hz and 28.42 A at 100 kHz, enabling reliable operation in high-frequency power circuits.
• Compact radial can design: φ63.5 × 135 mm package provides a smaller footprint compared with prior LNX/LNK options while maintaining performance for industrial use.
• Long operational life at elevated temperature: 5000 hours at 85°C under rated ripple current supports sustained service in demanding environments.
• Robust electrical safety margins: Insulation resistance >100 MΩ and AC 2500 V voltage proof between terminal and bracket enhance system reliability and safety testing.
• Designed for heavy charge–discharge cycling: Proven endurance to 50 million charge–discharge cycles (ΔV = 30% of rated voltage, 3 Hz), reducing replacement frequency in dynamic applications.
• RoHS compliant: Conforms to RoHS directive requirements for restricted substances, supporting regulatory compliance in end products.
