LNK2W682MSEHBN

The LNK2W682MSEHBN is a screw‑terminal aluminum electrolytic capacitor offering 6.8 mF capacitance at 450 V rated voltage. Designed as a general‑purpose, high‑voltage bulk capacitor in a radial can with screw terminals, it delivers high ripple current capability and a 5000‑hour load life at 85°C.

This part is suited for applications that require robust bulk energy storage and high ripple handling in a secure, screw‑terminal package, with a rated operating temperature range from −25°C to +85°C and RoHS compliance.

Key Features

• High capacitance and voltage: 6.8 mF (6800 µF) rated at 450 V for substantial bulk energy storage in high‑voltage circuits.
• Screw terminal mounting: Radial can with screw terminals provides a secure mechanical and electrical connection for high‑current applications.
• High ripple current capability: Rated ripple current of 20.7 A at 120 Hz (low frequency) and 28.98 A at 10 kHz (high frequency) to handle demanding AC ripple conditions.
• Endurance / load life: 5000 hours at 85°C under rated ripple and DC bias, supporting long operational life under specified conditions.
• Operating temperature range: −25°C to +85°C to accommodate a wide range of ambient environments.
• Controlled leakage and dissipation: Specified leakage current of 5000 µA and tan δ of 0.2 for predictable performance; datasheet defines leakage limits after voltage application.
• Form factor: Compact radial can sized φ76.2 × 155 mm (L: 15.5 × D: 7.62 cm) for installations where a screw‑terminal, high‑capacitance capacitor is required.
• Regulatory status: RoHS compliant.

Typical Applications

• High‑voltage power supplies: Bulk filtering and energy storage where 450 V rating and high capacitance are required to stabilize DC rails.
• Power conversion and inverters: DC link and smoothing duties benefiting from the part's high ripple current capability and screw‑terminal connections.
• Industrial power equipment: General‑purpose high‑voltage energy storage for systems operating within −25°C to +85°C and requiring long endurance.

Unique Advantages

• High energy density at high voltage: 6.8 mF at 450 V provides significant stored energy per component for bulk‑filtering roles.
• Designed for high ripple loads: Specified ripple currents at both low and high frequencies reduce the need for parallel components to share ripple duty.
• Screw‑terminal reliability: Robust mechanical and electrical termination suitable for high‑current connections and serviceable installations.
• Long rated life under load: 5000‑hour endurance at 85°C under rated ripple supports predictable maintenance intervals and lifecycle planning.
• Clear specification set: Defined leakage current, tan δ, and tolerance (±20%) simplify selection and performance verification.
• RoHS compliant: Supports regulatory requirements for lead‑free electronic assemblies.
