LNK2G682MSEJ

The LNK2G682MSEJ is a screw-terminal aluminum electrolytic capacitor designed for general-purpose high-voltage power applications. It delivers 6.8 mF (6800 µF) capacitance at a 400 V rating in a radial can with screw terminals, combining high stored energy with robust mounting for power systems.

Key value comes from its long endurance and wide operating range: a 5000-hour rated life at 85°C, a −25°C to +85°C operating window, and measured ripple-current specifications to support demanding AC and DC ripple conditions.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) nominal capacitance rated at 400 V, with a tolerance of ±20% (120 Hz, 20°C).
• Screw Terminal Mounting — Radial can package with screw terminals provides secure, low-resistance connections for power rails and easy installation in power assemblies.
• Endurance & Temperature — Rated for 5000 hours of endurance at 85°C; operational across −25°C to +85°C for consistent performance in variable environments.
• Ripple Current Ratings — Specified ripple-current handling of 20.7 A at 120 Hz and 28.98 A at 10 kHz, supporting substantial AC ripple conditions when appropriately applied.
• Loss Tangent (tan δ) — Specified tanδ of 0.2 (measurement frequency: 120 Hz at 20°C), enabling predictable dissipation characteristics.
• Leakage & Insulation — Leakage current after 5 minutes is ≤ 3√(C·V) µA or 5 mA (whichever is smaller) at 20°C; insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand — No abnormality under AC 2500 V applied for 1 minute between terminal and bracket, per datasheet test conditions.
• Durability After Endurance Test — After DC bias plus rated ripple current for 5000 hours at 85°C and recovery to 20°C: capacitance change within ±20% of initial value; tanδ ≤ 300% of initial specified value; leakage current ≤ initial specified value.
• Package & Size — φ90 × 120 L form factor, radial can with screw terminals; packaged for mass production in cardboard packing.
• Compliance — RoHS compliant per provided product information.
• Optional Electrolyte Variant — Flame‑retardant type electrolyte is available according to manufacturer notes.

Typical Applications

• General-purpose power systems — Energy storage and smoothing where a high-voltage, high-capacitance electrolytic capacitor is required.
• Power supply filtering — Bulk filtering in high-voltage DC rails benefiting from the capacitor’s ripple-current ratings and endurance.
• Industrial power electronics — Integration into assemblies that require screw-terminal mounting and secure mechanical connections.

Unique Advantages

• High energy density at elevated voltage: 6.8 mF at 400 V supplies substantial capacitance for high-voltage DC bus and filtering tasks.
• Long endurance under rated stress: 5000 hours at 85°C under DC bias plus ripple current provides predictable lifetime behavior for design planning.
• Robust ripple handling: Specified ripple currents at both low and high frequencies support a range of switching and line-frequency applications.
• Secure screw-terminal interface: Facilitates reliable electrical and mechanical connections in power assemblies and simplifies installation and maintenance.
• Measured electrical stability: Defined tanδ, leakage, and insulation resistance limits enable deterministic thermal and leakage budgeting in designs.
• Regulatory alignment: RoHS compliance supports use in regions with restricted substance requirements.
