LNK2W682MSEHBB

The LNK2W682MSEHBB is a screw-terminal aluminum electrolytic capacitor providing 6.8 mF of capacitance at a 450 V rating. Designed for general-purpose power applications, it pairs large bulk capacitance with a screw-terminal can package for secure, high-current connections.

Key engineering attributes include an operating temperature range of −25°C to 85°C, a 5000-hour endurance at 85°C under DC bias plus rated ripple current, and RoHS compliance—making it suitable for industrial and high-voltage DC rail applications where durable bulk energy storage is required.

Key Features

• Capacitance & Voltage — 6.8 mF (6800 µF) rated at 450 V for high-voltage bulk storage and smoothing.
• Tolerance — ±20% capacitance tolerance at 120 Hz, 20°C for predictable design margins.
• Endurance — Load life of 5000 hours at 85°C when subjected to DC bias plus rated ripple current; capacitance change remains within ±20% after the test.
• Temperature Range — Specified operation from −25°C to +85°C to accommodate a wide range of ambient environments.
• Ripple Current Capability — Rated ripple current: 20.7 A at 120 Hz and 28.98 A at 10 kHz, supporting high AC ripple scenarios in power conversion designs.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.2 (measurement conditions per datasheet), providing a quantified dissipation factor for design calculations.
• Robust Termination — Screw terminal mounting in a radial can package for secure mechanical and electrical connections in high-current installations.
• Polarized — Polarized electrolytic design for DC applications where polarity is controlled.
• Mechanical Dimensions — Diameter φ76.2 mm with length 155 mm (size listed as L: 15.5 × D: 7.62 cm), enabling planners to verify enclosure and bracket fit.
• Electrical Safety & Leakage — Leakage current after 5 minutes is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20°C); insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket; voltage proof AC 2500 V for 1 minute between terminal and bracket as defined in the datasheet.
• Compliance — RoHS compliant per the product data.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage on high-voltage DC rails where 450 V rating and large capacitance are required.
• Industrial power conversion — Filtering and ripple handling in converters and inverters that operate within the −25°C to +85°C temperature window.
• High-voltage DC systems — Energy buffering and decoupling on 350–500 V class DC systems (part-specific rating: 450 V).

Unique Advantages

• High bulk capacitance at elevated voltage: 6.8 mF at 450 V provides substantial energy storage for smoothing and hold-up functions.
• Long-rated life under load: 5000 hours at 85°C with DC bias plus rated ripple current, with capacitance change within ±20%, supports long-term reliability planning.
• High ripple handling: Specified ripple currents of 20.7 A (120 Hz) and 28.98 A (10 kHz) enable designs that face significant AC stress.
• Secure screw-terminal connection: Radial can with screw terminals simplifies high-current wiring and mechanical retention compared with leaded types.
• Measured electrical characteristics: Specified tan δ (0.2) and quantified leakage/insulation values allow designers to include conservative, verifiable parameters in system models.
• Regulatory compatibility: RoHS compliance facilitates use in assemblies targeting regional hazardous-substance requirements.
