LNK2W682MSEJBN

The LNK2W682MSEJBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNK series. It provides 6800 µF capacitance at a 450 V rated voltage in a radial can with screw terminals for secure, low‑impedance connections.

Targeted for general‑purpose power applications, this capacitor combines high voltage capability, substantial bulk capacitance and defined ripple‑current ratings to support AC/DC power conversion, filtering and energy storage needs in industrial and commercial equipment.

Key Features

• Capacitance and Voltage: 6.8 mF (6800 µF) nominal capacitance rated at 450 V for high‑voltage bulk capacitance requirements.
• Screw Terminal Mounting: Radial can with screw terminals (can - screw terminals) for robust mechanical and electrical connections in panel or chassis installations.
• Ripple Current Capability: Rated ripple current of 20 A at 120 Hz (low frequency) and 28 A at 10 kHz (high frequency), enabling handling of significant AC ripple in power circuits.
• Endurance and Operating Temperature: Designed for 5000 hours life at 85°C, with an operating temperature range of −25°C to +85°C.
• Leakage Current: Specified leakage current of 5000 µA; the series datasheet also states leakage limits based on the 3√(C·V) rule or 5 mA, whichever is smaller, after voltage application.
• Reliability Tests: Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket, and voltage proof of AC 2500 V for 1 minute between terminal and bracket as described in the series datasheet.
• Form Factor: φ90 × 125 mm size (L: 12.5 × D: 9 cm) suitable for installations requiring a compact, high‑capacitance, high‑voltage can.
• RoHS Compliance: Compliant with RoHS directive as stated in the product information.

Typical Applications

• General Power Supplies: Bulk energy storage and smoothing in general‑purpose AC/DC and DC/DC conversion systems where high voltage and large capacitance are required.
• Industrial Equipment: Use in industrial power systems and control cabinets that require robust screw‑terminal mounting and high ripple handling at elevated temperatures.
• Energy Filtering: Filtering and decoupling of high‑voltage DC buses and intermediate circuits in commercial power equipment.

Unique Advantages

• High Voltage Handling: 450 V rating enables deployment in higher‑voltage DC circuits without series stacking.
• Substantial Bulk Capacitance: 6.8 mF of capacitance provides significant energy storage for smoothing and transient support.
• Strong Ripple Performance: Defined ripple currents of 20 A (120 Hz) and 28 A (10 kHz) help manage both low‑ and high‑frequency ripple in power applications.
• Robust Mechanical Connection: Screw terminal package provides durable, low‑resistance connections for chassis‑mounted or high‑vibration environments.
• Proven Endurance: 5000 hours rated life at 85°C with specified endurance limits for capacitance change and dissipation, supporting predictable long‑term performance.
• Compliance and Safety Checks: Insulation resistance and voltage proof characteristics in the datasheet support safe integration between terminal and bracket.
