LNC2W682MTEH

The LNC2W682MTEH is a screw‑terminal (stud bolt mount) aluminum electrolytic capacitor in Nichicon’s LNC series, rated at 6800 µF and 450 V. It is designed for industrial power electronics where high capacitance, high voltage tolerance and elevated ripple handling are required.

Typical use cases include industrial power supplies, inverter circuitry and regenerative voltage applications for AC servomotors and general inverters. The part offers high ripple current capability, extended load life at elevated temperature, and a compact can-style screw‑terminal package for secure mechanical mounting.

Key Features

• High Capacitance & Voltage — 6800 µF nominal capacitance with a rated voltage of 450 V for bulk energy storage and DC link applications.
• Elevated Ripple Handling — Low‑frequency ripple current of 23.8 A at 120 Hz and high‑frequency ripple current of 33.32 A at 100 kHz to support high charge/discharge and inverter workloads.
• Long Load Life — Rated for 5000 hours at 85°C under rated ripple conditions, delivering predictable endurance in demanding thermal environments.
• Screw Terminal / Stud Bolt Mount — Radial can with screw terminals and stud mount configuration for robust electrical connection and mechanical fixation in industrial assemblies.
• Operating Temperature Range — −40°C to +85°C to accommodate a wide range of industrial ambient conditions.
• Leakage and Dissipation — Leakage current specified at up to 5000 µA and tan δ (DF) at 0.2 (measured at 20°C, 120 Hz), providing clear electrical characteristics for circuit design.
• RoHS Compliant — Conforms to RoHS requirements for use in assemblies where restricted substances compliance is required.

Typical Applications

• Industrial Inverters — Bulk DC link and smoothing capacitor in inverter power stages where 450 V ratings and high ripple capability are necessary.
• AC Servomotor Drives — Supports regenerative voltage and high‑speed charge/discharge cycles in servo and motor drive systems.
• Power Supplies — Energy storage and filtering in industrial power supplies subject to sustained ripple currents and elevated operating temperatures.
• High‑Frequency Power Electronics — Suitable for circuits requiring high ripple current at both low and high frequencies (120 Hz and 100 kHz data provided).

Unique Advantages

• High energy density for 450 V systems: 6800 µF capacitance at 450 V supports significant energy storage in DC link and smoothing applications.
• High ripple capability across frequencies: Specified ripple currents of 23.8 A (120 Hz) and 33.32 A (100 kHz) enable use in both line‑frequency and high‑frequency switching environments.
• Proven endurance at elevated temperature: 5000‑hour rated life at 85°C under ripple load provides predictable longevity for industrial deployments.
• Mechanically robust mounting: Screw terminals and stud bolt mount simplify secure installation and provide reliable electrical connection in heavy‑duty assemblies.
• Compact can package: φ76.2 × 145 mm dimensions (L: 14.5 × D: 7.62 cm) deliver a smaller footprint while maintaining high ripple performance as noted for the LNC series.
• Regulatory compliance: RoHS conformity supports use in assemblies requiring restricted‑substance compliance.
