The LNK2W222MSEHBN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNK series, offering 2.2 mF (2200 µF) capacitance at a 450 V rating. Designed for general-purpose applications, it provides high-voltage bulk capacitance with screw-terminal convenience for robust electrical and mechanical connections in production environments.

Built for continuous operation across a wide ambient range and mass-production use, this component balances high ripple handling, long life at elevated temperature, and RoHS compliance.

Key Features

• Capacitance and Voltage — 2.2 mF (2200 µF) rated at 450 V, suitable for high-voltage bulk energy storage in general-purpose circuits.
• Screw Terminal Mounting — Radial can with screw terminals simplifies secure, repeatable connections for heavy-current or mechanically demanding assemblies.
• High Ripple Current Capability — 9.4 A low-frequency ripple (120 Hz) and 13.16 A high-frequency ripple (10 kHz) ratings support demanding AC ripple conditions.
• Leakage and Loss — Specified leakage current of 2980 µA and tan δ of 0.2 provide measurable electrical characteristics for design verification.
• Temperature and Lifetime — Rated operating range −25°C to +85°C with a load life of 5000 hours at 85°C under specified ripple conditions.
• Compact, Smaller-sized LNK Package — φ76.2 × 85L form factor (L: 8.5 × D: 7.62 cm) supports space-conscious designs while providing screw-terminal robustness.
• RoHS Compliant — Meets RoHS directive requirements.
• Frequency Coefficient Information — Series frequency coefficients include 1.00 at 120 Hz and up to 1.40 at 10 kHz or more, useful for ripple-current scaling across frequency.
• Production and Marking — Supplied for mass production with white-on-black sleeve marking and cardboard packing.

Typical Applications

• General-purpose power electronics — Provides high-voltage bulk capacitance for energy storage and smoothing in general-purpose circuits where 450 V rating is required.
• High-ripple environments — Suitable where sustained ripple current at both low and high frequencies must be supported, leveraging specified 120 Hz and 10 kHz ripple ratings.
• Production assemblies — Screw-terminal packaging and cardboard-packed mass-production supply enable repeatable installation in manufactured products.

Unique Advantages

• High-voltage bulk storage: 2.2 mF at 450 V gives substantial energy-holding capability in a single capacitor for designs requiring high DC voltage handling.
• Robust ripple handling: Specified ripple currents of 9.4 A (120 Hz) and 13.16 A (10 kHz) reduce the need for parallel components in many applications.
• Long life at elevated temperature: 5000 hours rated life at 85°C under rated ripple ensures predictable endurance in high-temperature operating conditions.
• Secure mechanical and electrical connection: Screw terminals provide durable terminations for higher-current or vibration-prone installations.
• Traceable production form factor: Smaller-sized LNK package and standardized marking support consistent integration in mass-production builds.
• Regulatory alignment: RoHS compliance helps streamline environmental conformity requirements.
