LNK2V122MSEFBN

The LNK2V122MSEFBN is a screw-terminal aluminum electrolytic capacitor in Nichicon’s LNK series, offering 1200 µF capacitance at a 350 V rating and designed for general-purpose power applications. It features a radial can with screw terminals and a compact “smaller-sized” footprint (φ51 × 75 mm) for secure mechanical and electrical connections.

Engineered for systems that require high-voltage bulk capacitance with robust ripple handling, this capacitor delivers a 5000 hour endurance at 85°C, RoHS compliance, and specified ripple current performance across low and high frequencies.

Key Features

• Rated Capacitance & Voltage: 1.2 mF (1200 µF) at 350 V — provides substantial bulk capacitance for high-voltage circuits.
• Mounting & Package: Screw-terminal radial can (φ51 × 75 mm) for secure, high-reliability connections in panel- or chassis-mounted power assemblies.
• Operating Temperature Range: -25°C to 85°C — specified for typical general-purpose environments.
• Endurance / Lifetime: 5000 hours at 85°C under rated ripple current — designed for extended service under continuous ripple load.
• Ripple Current Capability: 5.5 A at 120 Hz and 7.7 A at 10 kHz — supports both low- and high-frequency ripple conditions.
• Leakage, Loss, and Tolerance: Leakage current listed as 2.07 mA, tan δ of 0.2, and capacitance tolerance ±20% — clear electrical characteristics for design validation.
• Regulatory / Production Status: RoHS compliant and in mass production — suitable for production BOMs requiring environmental compliance.

Typical Applications

• General-purpose power supplies: Bulk smoothing and energy storage where a 350 V, 1200 µF capacitor is required to stabilize DC rails.
• High-voltage DC filtering: DC link or intermediate bus filtering in power conversion equipment that benefits from screw-terminal mounting for mechanical robustness.
• Industrial power equipment: Applications that demand sustained ripple handling and long endurance at elevated operating temperatures up to 85°C.

Unique Advantages

• High-voltage bulk capacitance: 1200 µF at 350 V delivers substantial energy storage for high-voltage circuits without stacking multiple components.
• Screw-terminal reliability: Robust screw terminals simplify strong electrical connections and secure mounting in mechanically demanding assemblies.
• Designed for continuous ripple: Specified ripple current ratings at 120 Hz and 10 kHz support designs with both low- and high-frequency ripple loads.
• Extended endurance at elevated temperature: 5000 hours at 85°C under rated ripple current provides predictable life for long-term installations.
• Clear electrical specs for design margins: Explicit values for leakage current (2.07 mA), tan δ (0.2), and ±20% tolerance aid accurate simulation and selection.
• Regulatory-ready production: RoHS compliance and mass-production availability simplify procurement and environmental compliance planning.
