LNK2W222MSEH

The LNK2W222MSEH from Nichicon is a screw-terminal, radial aluminum electrolytic capacitor in the LNK series engineered for high-voltage, high-ripple applications. With a rated capacitance of 2200 µF (2.2 mF) at 450 V and a compact screw-terminal can, it is designed for general-purpose power applications that require robust ripple handling and long life at elevated temperatures.

Key design attributes include a 5000-hour endurance at 85°C, RoHS compliance, and screw-terminal mounting for secure electrical and mechanical connections in industrial and power electronics assemblies.

Key Features

• High Capacitance at High Voltage — 2200 µF rated capacitance at 450 V for energy storage and DC bus applications that require substantial charge capacity.
• Screw Terminal Mounting — Radial can with screw terminals provides a secure, low-impedance connection suited to high-current installations.
• Robust Ripple Current Capability — Rated ripple current of 9.4 A at 120 Hz (low frequency) and 13.16 A at 10 kHz (high frequency), enabling effective smoothing under heavy AC ripple conditions.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.2 at 20°C and 120 Hz, supporting predictable dissipation performance in filter and smoothing roles.
• Endurance and Temperature Range — Load life of 5000 hours at 85°C and an operating temperature range of −25°C to +85°C for stable performance in elevated-temperature environments.
• Polarized, General-Purpose Design — Polarized aluminum electrolytic construction with ±20% capacitance tolerance for general-purpose power-electronics use.
• Dimensions and Packaging — Physical size φ76.2 × 85 mm (L: 8.5 × D: 7.62 cm) in a radial can package; supplied in cardboard packing and in mass-production status.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• High‑voltage DC bus filtering — Large capacitance at 450 V provides energy buffering and smoothing for DC link circuits where high-voltage ripple suppression is required.
• Power supply smoothing — High ripple current ratings at both low and high frequency make the capacitor suitable for bulk smoothing on rectified supplies and switched‑mode power supplies.
• Industrial power electronics — Screw-terminal mounting and long endurance at 85°C support use in industrial converters and power modules that demand secure electrical connections and sustained performance.

Unique Advantages

• High-energy storage at 450 V — Enables compact implementations of high-voltage filtering and energy buffering without parallel arrays of smaller parts.
• Engineered for sustained ripple load — Specified ripple currents at 120 Hz and 10 kHz allow designers to match the component to expected frequency content and thermal loading.
• Long rated life at elevated temperature — 5000-hour endurance at 85°C provides predictable aging characteristics for maintenance planning and reliability assessments.
• Secure screw-terminal connections — Simplifies installation and serviceability in assemblies that require robust mechanical and electrical attachment.
• Clear, verifiable specifications — Leakage current, tan δ, capacitance tolerance, and insulation/voltage proof characteristics are specified for engineering validation.
