LNK2V682MSEGBN

The LNK2V682MSEGBN from Nichicon is a screw-terminal aluminum electrolytic capacitor offering 6.8 mF capacitance at a 350 V rating in a radial can with M5 screw terminals. Designed for general-purpose power applications, it combines high capacitance, substantial ripple handling, and a long rated life to support DC link, filtering and energy-storage duties in medium-voltage systems.

This part is RoHS compliant and intended for mass production deployments where robust mechanical connections, reliable long-term performance and easy serviceability are required.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 350 V provides substantial energy storage for DC-link and bulk-filtering functions.
• Screw-Terminal Package — Radial can with M5 screw terminals for secure, high-current connections and straightforward installation or replacement.
• High Ripple Capability — Rated ripple currents of 19.6 A at 120 Hz and 27.44 A at 10 kHz support demanding AC ripple and switching environments.
• Long Endurance — Load life rated at 5000 hours at 85°C under rated ripple conditions for sustained reliability in elevated-temperature installations.
• Operational Temperature Range — Specified for −25°C to +85°C to accommodate a wide range of industrial ambient conditions.
• Electrical Characteristics — Capacitance tolerance ±20%, tangent of loss angle (tan δ) 0.2, and leakage current specified at 4.48 mA for predictable performance and design margining.
• Packaging & Production — Supplied in cardboard packing and available in mass production quantities for volume manufacturing needs.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy storage in medium-voltage power supplies, leveraging 6.8 mF at 350 V and high ripple current ratings to smooth DC outputs.
• Motor Drive DC Links — DC-link smoothing in motor drives where screw-terminal mounting supports robust high-current busbar or cable connections.
• Uninterruptible Power Supplies (UPS) — Energy buffering and filtering in UPS systems that require sustained performance and a 5000-hour endurance at elevated temperature.
• Power Conversion & Inverters — Bulk capacitance for inverter/DC-DC converter stages, taking advantage of the capacitor’s frequency-dependent ripple capability up to 10 kHz.

Unique Advantages

• High Energy Density at 350 V — 6.8 mF nominal capacitance at 350 V provides significant stored energy in a compact screw-terminal can (φ63.5 × 155 mm), helping reduce the number of parallel components.
• Designed for High Ripple Environments — Specified ripple currents (19.6 A at 120 Hz, 27.44 A at 10 kHz) enable reliable operation under heavy AC ripple and switching stresses.
• Extended Load Life — 5000 hours at 85°C under rated ripple ensures predictable long-term behavior in continuous-duty installations.
• Serviceable Mechanical Connection — Screw terminals simplify installation, maintenance and replacement compared with soldered leaded devices.
• Clear Electrical Specifying Data — Published values for tan δ (0.2), leakage current (4.48 mA), and ±20% capacitance tolerance support accurate circuit design and margining.
• RoHS Compliance — Conforms to RoHS requirements for use in regulated assemblies.
