LNK2W332MSEGBN

The LNK2W332MSEGBN is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNK series, offering 3.3 mF (3300 µF) capacitance at a 450 V rating. Designed for general-purpose high-voltage DC applications, it pairs bulk energy storage with screw-terminal robustness for secure electrical and mechanical connection.

Key value comes from a long load life (5000 hours at 85°C), significant ripple-current capability at both low and high frequencies, and RoHS compliance—features that support reliable filtering and smoothing in demanding industrial and power electronics environments.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) rated at 450 V, providing substantial bulk capacitance for high-voltage DC smoothing and energy storage.
• Screw Terminal Package — Radial can with screw terminals (M5 nominal bolt for φ63.5), enabling secure, low-resistance connections and easy replacement or assembly.
• Thermal and Lifetime Performance — Rated for operation from −25°C to +85°C with a guaranteed load life of 5000 hours at 85°C under rated ripple conditions.
• Ripple Current Capability — Rated ripple current of 12.1 A at 120 Hz and 16.94 A at 100 kHz provides effective performance across low and high frequency ripple environments.
• Electrical Losses and Leakage — Specified tan δ of 0.2 and measured leakage current of 3650 µA, enabling designers to account for dissipation and self-discharge in system budgets.
• Form Factor — Physical size φ63.5 × 115 mm (D: 6.35 cm, L: 11.5 cm) for applications where a compact high-voltage capacitor with screw terminals is required; supplied in cardboard packing for mass production handling.
• Regulatory — RoHS compliant, meeting the referenced RoHS directive requirements.

Typical Applications

• General-purpose high-voltage DC smoothing — Bulk capacitance and 450 V rating make this capacitor suitable for smoothing and energy buffering in high-voltage DC rails.
• Power conversion and filtering — Screw-terminal mounting and high ripple-current capability support use in power supplies and converter output filters where robust connections are required.
• Industrial power systems — Long 5000-hour life at 85°C and broad operating temperature range support continuous operation in industrial power conditioning and control equipment.

Unique Advantages

• High-voltage bulk energy storage: 3300 µF at 450 V provides substantial stored energy for high-voltage DC systems, reducing the number of parallel parts required.
• Screw-terminal reliability: Mechanical screw terminals enable secure, low-impedance connections that simplify assembly and maintenance in heavy-duty installations.
• Frequency-spanning ripple performance: Rated ripple current figures for both 120 Hz and 100 kHz let designers size components for low- and high-frequency ripple environments.
• Long operational life under load: 5000 hours at 85°C with rated ripple current ensures predictable aging and helps plan maintenance/replacement schedules.
• Clear electrical characteristics: Specified tan δ and leakage current values allow accurate thermal and leakage budgeting in system-level designs.
• RoHS compliant and production-ready: Cardboard-packed for mass production and compliant with RoHS directives for regulatory alignment.
