LNK2G682MSEJBB

The LNK2G682MSEJBB is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNK series. It provides 6.8 mF (6800 µF) capacitance at a 400 V rated voltage in a radial can with screw terminals for secure, high-current connections.

Engineered for general-purpose power applications, this capacitor offers long-term endurance at elevated temperature (5000 hours at 85°C under rated ripple conditions) and RoHS compliance for regulatory compatibility.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 400 V with ±20% tolerance, providing substantial bulk energy storage for high-voltage circuits.
• Screw Terminal Construction — Radial, can-style package with screw terminals for robust mechanical retention and reliable high-current connections.
• Operational Temperature Range — Rated for operation from −25°C to +85°C to match a broad set of general-purpose environments.
• Long Endurance — Load-life specification of 5000 hours at 85°C when subjected to DC bias plus rated ripple current; capacitance change is specified to remain within ±20% after the endurance test.
• Ripple Current Capability — Designed to handle significant ripple: 20.7 A at 120 Hz and 28.98 A at 10 kHz as specified for this part.
• Insulation & Voltage Proof — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute without abnormality between terminal and bracket.
• Leakage Current — After 5 minutes’ application of rated voltage at 20°C, leakage current is specified not more than 3√CV (µA) or 5 mA, whichever is smaller.
• Package Dimensions — Compact radial can dimensions listed as L: 12 × D: 9 cm to assist mechanical planning and layout.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Bulk energy storage and smoothing in 400 V-class power supplies and converters where high capacitance and ripple handling are required.
• Industrial power electronics — Energy buffering and DC-link support in industrial assemblies that require screw-terminal mounting for secure connections.
• Repair and maintenance-friendly designs — Systems that benefit from screw-terminal serviceability and straightforward replacement in the field.

Unique Advantages

• High capacitance at high voltage — 6.8 mF at 400 V provides significant bulk charge storage for demanding DC systems.
• Robust ripple handling — Specified ripple current values at both low and high frequencies help maintain performance under real-world AC ripple conditions.
• Durability under elevated temperature — 5000-hour load-life rating at 85°C supports longer service intervals in warm operating environments.
• Secure, serviceable connections — Screw-terminal package simplifies installation, replacement and mechanical retention for heavy-current applications.
• Clear electrical qualification — Defined insulation resistance, leakage current limits, and voltage-proof testing provide measurable acceptance criteria for design-in.
• Regulatory readiness — RoHS compliance supports use in assemblies that must meet contemporary hazardous-substance regulations.
