LNK2W222MSEG

The LNK2W222MSEG is a screw-terminal aluminum electrolytic capacitor in Nichicon's LNK series, offering 2200µF capacitance at a 450V rating. It is designed as a smaller-sized, high-ripple-capability solution for general-purpose power applications where high voltage handling and robust ripple performance are required.

With an 85°C operating limit, a rated load life of 5000 hours at 85°C, and RoHS compliance, this capacitor targets applications that need durable DC-link or smoothing components with secure screw-terminal connections and straightforward mechanical mounting.

Key Features

• Electrical Capacity: 2.2 mF (2200µF) capacitance with ±20% tolerance, suitable for bulk energy storage and smoothing tasks within its rated voltage.
• High Voltage Rating: 450 V rated voltage for higher-voltage power electronics and DC bus applications.
• High Ripple Current: Specified ripple capability of 9 A at 120 Hz and 12.6 A at 10 kHz, supporting elevated AC components on the DC bus.
• Screw Terminal Mounting: Radial can with screw terminals provides secure, low-resistance electrical connections and simplified field serviceability.
• Temperature and Lifetime: Operating range −25°C to +85°C with a load-life rating of 5000 hours at 85°C under rated ripple conditions.
• Leakage and Insulation Characteristics: Series specification limits leakage current to not more than 3√CV (µA) or 5 mA after 5 minutes at 20°C; insulation resistance is specified as more than 100 MΩ at DC 500 V between terminal and bracket.
• Compliance and Construction: RoHS compliant and available in a smaller-sized screw-terminal can for space-conscious designs.
• Physical Dimensions: Package dimensions: length 9.0 cm × diameter 6.35 cm; polarized radial can with screw terminals for bracket mounting.

Typical Applications

• General-purpose power systems: Bulk smoothing and energy storage in power supplies and industrial power electronics where a 450V rating and high ripple capability are required.
• DC-link and inverter circuits: DC-link smoothing in equipment that imposes substantial ripple currents at mid-to-high frequencies.
• Industrial equipment: Power filtering and energy buffering in machinery and control systems that demand secure, serviceable screw-terminal connections.

Unique Advantages

• High-voltage capability: 450V rating enables use in elevated-voltage DC buses and circuits without stacking capacitors.
• Designed for ripple-heavy environments: Published ripple current values at 120 Hz and 10 kHz provide quantifiable margins for designs with significant AC components.
• Durability under load: 5000-hour rated load life at 85°C supports longer service intervals in continuous-duty applications.
• Robust, serviceable connections: Screw-terminal package simplifies assembly and maintenance compared with solder-only terminals.
• Compact footprint for its class: Smaller-sized radial can provides a space-efficient solution for high-voltage capacitance needs.
• RoHS compliant: Meets environmental directive requirements for materials compliance.
