LNC2H682MTEJ

The LNC2H682MTEJ is a 6.8 mF (6800 µF), 500 V aluminum electrolytic capacitor in a stud (screw terminal) can package designed for industrial power electronics. It is part of Nichicon’s LNC series, engineered for applications that require high ripple current capacity and long operational life under elevated temperatures.

This stud bolt mount capacitor is suited for industrial power supplies and inverter circuitry, including high-frequency regenerative voltage for AC servomotors and general inverters, where high voltage, large capacitance and robust ripple-handling are required.

Key Features

• Capacitance and Tolerance – 6.8 mF (6800 µF) nominal with ±20% tolerance (measured at 120 Hz, 20°C), providing bulk energy storage for DC-link and smoothing applications.
• High Voltage Rating – Rated for 500 V operation to support high-voltage power supply rails and inverter DC-links.
• High Ripple Current Handling – Low-frequency ripple current 30 A (120 Hz) and high-frequency ripple current 42 A (100 kHz), enabling sustained charge/discharge and filtering under heavy dynamic loads.
• Loss Characteristics – Specified tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz for predictable dissipation behavior.
• Leakage Current – Leakage current specified at 5000 µA, defined after voltage application, for planning standby and leakage-related design considerations.
• Long Endurance – Rated load-life of 5000 hours at 85°C under rated ripple conditions to support reliable long-term service in harsh environments.
• Wide Operating Temperature – Operates across –40°C to +85°C for use in a range of industrial thermal conditions.
• Package & Mounting – Stud bolt mount, radial can with screw terminals, designed for secure mechanical and electrical connection in power assemblies. Packaging type: cardboard packing.
• RoHS Compliant – Conforms to RoHS requirements for restricted substances.

Typical Applications

• Industrial Power Supplies – Bulk DC-link smoothing and energy storage in high-voltage industrial converters and rectifier systems.
• Inverter and Motor Drives – Handling regenerative and high-frequency currents for AC servomotor drives and general inverter systems.
• High-Power Filtering – Ripple attenuation and charge/discharge buffering in high-current power electronics where sustained ripple capability is required.

Unique Advantages

• High-energy, high-voltage combination: 6.8 mF at 500 V provides significant stored energy for DC-link and bulk filtering in compact assemblies.
• Superior ripple capability: 30 A (120 Hz) and 42 A (100 kHz) ripple ratings let you design for both low- and high-frequency stress without oversizing capacitance.
• Designed for long duty life: 5000-hour endurance at 85°C under rated ripple conditions supports extended maintenance intervals and reliable operation.
• Robust mounting and connections: Stud bolt mount with screw terminals ensures secure mechanical fastening and low-impedance electrical contact in power modules.
• Smaller-sized, high-ripple design: Engineered to deliver high ripple current in a compact cylindrical can (φ90 × 145 mm), helping optimize board and enclosure space.
• Compliance-ready: RoHS compliance supports regulatory and environmental requirements in industrial deployments.
