LNC2V682MSEH

The LNC2V682MSEH is a screw-terminal, aluminum electrolytic capacitor from Nichicon's LNC series designed for industrial power systems. It provides 6.8 mF capacitance at 350 V in a radial can with screw terminals, engineered for applications that require high ripple handling and long operational life.

Its design emphasizes higher ripple-current capability and compact sizing for inverter and regenerative circuits, with a rated lifetime of 5000 hours at 85°C and a wide operating range from −40°C to +85°C.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 350 V for bulk energy storage in high-voltage power circuits.
• Screw Terminal Mount — Radial can with screw terminals for secure, high-current connections and straightforward mechanical mounting.
• High Ripple Current — 19.7 A at 120 Hz and 27.58 A at 100 kHz to support high-frequency and high-current ripple conditions.
• Endurance — 5000 hours load life at 85°C when DC bias plus rated ripple current is applied; meets LNC series endurance criteria.
• Temperature Range — Operates from −40°C to +85°C, suitable for industrial environments within that range.
• Loss Angle (tan δ) — tan δ 0.2 (measurement: 120 Hz at 20°C), indicating dissipation characteristics under specified conditions.
• Leakage Current — 4.62 mA as specified for the part.
• Compact Mechanical Size — φ76.2 × 100L (approx. L: 10 cm × D: 7.62 cm) for a high-capacitance, high-voltage solution in a relatively small footprint.
• Regulatory — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial inverter power supplies — Bulk energy storage and ripple smoothing in inverter front ends for motor drives and power conversion.
• AC servomotor regenerative circuits — Handles high-frequency regenerative voltages and frequent charge–discharge loading.
• High-speed charge–discharge systems — Supports applications subject to rapid cycling and high-speed energy transfer.

Unique Advantages

• High ripple-current capability — Rated ripple currents at both 120 Hz and 100 kHz reduce heating under heavy AC ripple loads.
• Long rated life at elevated temperature — 5000 hours at 85°C provides predictable endurance in demanding industrial environments.
• Secure screw-terminal connections — Screw-terminal package simplifies installation and provides robust electrical/mechanical connections for high-current paths.
• Compact high-voltage energy storage — 6.8 mF at 350 V in a φ76.2 × 100L can offers substantial capacitance without excessively large packaging.
• Wide operating temperature range — −40°C to +85°C supports a broad set of industrial use conditions.
• RoHS compliance — Meets applicable RoHS directive requirements for regulated substances.
