LNC2V682MTEG

The LNC2V682MTEG is a screw‑terminal (stud bolt mount) aluminum electrolytic capacitor from Nichicon’s LNC series, rated 6800 µF at 350 V. It is designed for industrial power electronics where compact bulk capacitance and high ripple handling are required.

Targeted use cases include inverter circuitry and high‑frequency regenerative circuits for AC servomotors and general inverters. The device combines high ripple‑current capability with a 5000‑hour endurance at 85°C to support sustained operation under heavy electrical loading.

Key Features

• Core Electrical — 6800 µF nominal capacitance with ±20% tolerance, polarized design suitable for bulk energy storage and smoothing at 350 V rated voltage.
• High Ripple Current — Low‑frequency ripple current of 20.3 A (120 Hz) and high‑frequency ripple current of 28.42 A (100 kHz), enabling handling of both mains-frequency and switching‑frequency stress.
• Endurance and Reliability — Specified life of 5000 hours at 85°C with rated ripple current applied, meeting the LNC series endurance criteria for industrial applications.
• Thermal Range — Operates across −40°C to +85°C, supporting a wide range of industrial ambient conditions.
• Mechanical & Mounting — Stud bolt (screw terminal) mount in a radial can package (φ63.5 × 135 mm) for secure high‑current connections and straightforward mechanical installation.
• Leakage and Loss — Specified leakage current of 4620 µA and tangent of loss angle (tan δ) of 0.2 measured at 20°C, 120 Hz for predictable dissipation characteristics.
• Compliance & Availability — RoHS‑compliant and listed as mass production status within the LNC series.

Typical Applications

• Industrial Inverter Power Supplies — Bulk smoothing and energy buffering in inverter front‑ends where 350 V systems require high capacitance and sustained ripple handling.
• AC Servomotor Regenerative Circuits — Support for high‑frequency regenerative voltages and rapid charge/discharge cycles in motor drive systems.
• High‑Speed Charge/Discharge Systems — Suitable for applications that place repeated charge/discharge stress on capacitors, supported by the LNC series endurance specification.
• Power Electronics Filtering — Bulk decoupling and filtering for converters and DC bus architectures subject to both low‑ and high‑frequency ripple currents.

Unique Advantages

• High ripple‑current capability: 20.3 A at 120 Hz and 28.42 A at 100 kHz provide margin for both mains and switching ripple stress, reducing the need for parallel parts.
• Compact high‑capacitance package: 6800 µF in a φ63.5 × 135 mm can offers significant bulk capacitance in a stud‑mount form factor for dense power assemblies.
• Long rated life at elevated temperature: 5000 hours at 85°C under rated ripple current supports prolonged operation in demanding industrial environments.
• Wide operating temperature: −40°C to +85°C enables deployment across varied ambient conditions without derating the core application.
• Robust mounting and high‑current terminals: Stud bolt screw terminals provide reliable high‑current connections and simplify installation in power racks and panels.
• RoHS compliant and production ready: Meets RoHS requirements and is available as a mass production part for consistent supply in production designs.
