LNC2G682MSEGBB

The LNC2G682MSEGBB is a screw-terminal aluminum electrolytic capacitor from Nichicon designed for industrial power electronics. It delivers 6800 µF at 400 V in a compact radial can with screw terminals, optimized for inverter circuitry and high-frequency regenerative voltage applications.

Engineered for demanding load and ripple environments, this capacitor offers higher ripple-current capability in a smaller size, a long 5000-hour load life at 85°C, and stability across –40°C to +85°C operating temperature.

Key Features

• Capacitance and Voltage — 6800 µF nominal capacitance with a 400 V rated voltage and ±20% capacitance tolerance (at 120 Hz, 20°C).
• High ripple-current capability — Rated ripple current of 23.8 A at 120 Hz and 33.32 A at 100 kHz, supporting heavy AC and high-frequency loading profiles.
• Long load life — Endurance specified as 5000 hours with rated ripple current at 85°C, with defined limits for capacitance change, tan δ, and leakage current after the test.
• Temperature and stability — Rated for operation from –40°C to +85°C; impedance stability characterized down to –40°C (Z(–40°C)/Z(+20°C) ≤ 8).
• Robust charge-discharge endurance — Specified endurance for charge-discharge behavior over 50 million cycles (ΔV = rated voltage × 0.3, 3 Hz) with limits on capacitance, tan δ and leakage current.
• Construction and mounting — Screw terminal type in a radial can package for secure electrical and mechanical connections; printed marking (white on black sleeve) for easy identification.
• Leakage, insulation and voltage proof — Leakage after 5 minutes not more than 3√(V) µA or 5 mA (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V, 1 minute voltage proof between terminal and bracket.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact footprint — Smaller-sized and higher ripple capability compared to LNX and LNK series; physical size listed as L: 16.5 × D: 6.35 cm.

Typical Applications

• Industrial inverter power supplies — Energy storage and smoothing for inverter front-ends where sustained ripple and long life at 85°C are required.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltage from motor drives and supports repetitive charge-discharge loading.
• General inverter systems — Bulk capacitance and high ripple-current handling for inverter DC-link and intermediate circuits.

Unique Advantages

• Higher ripple-current handling: Specified 23.8 A at 120 Hz and 33.32 A at 100 kHz to support heavy AC and high-frequency loads, reducing thermal stress in demanding designs.
• Smaller-sized solution: Designed to provide higher ripple performance in a reduced package compared with LNX and LNK series, enabling tighter power-system packaging.
• Proven endurance under load: 5000-hour rated life at 85°C with defined post-test criteria for capacitance, tan δ and leakage current, providing predictable long-term performance.
• High-frequency and charge-discharge resilience: Qualified for 50 million charge-discharge cycles at specified conditions, making it suitable for rapid dynamic energy exchanges.
• Secure, serviceable connections: Screw-terminal mounting simplifies installation and replacement in industrial equipment.
• Standards-driven specifications: Comprehensive leakage, insulation resistance and voltage-proof limits for reliable integration into safety-conscious designs.
