LNK2W122MSEF

The LNK2W122MSEF from Nichicon is a screw-terminal aluminum electrolytic capacitor delivering 1.2 mF capacitance at a 450 V rated voltage. Designed as a general-purpose, high-voltage electrolytic solution, it combines a compact radial can package with robust ripple handling and long endurance for power-focused assemblies.

Targeted at engineers and procurement for industrial and power-electronics designs, the part offers high-frequency and low-frequency ripple capability, 5000 hours of rated life at 85°C, and RoHS compliance for environmentally conscious production.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance rated for 450 V DC, suited to high-voltage smoothing and energy storage in general-purpose designs.
• Tolerance — ±20% capacitance tolerance at 120 Hz, 20°C, providing predictable performance for design margin calculations.
• Ripple Current Performance — 6.3 A low-frequency ripple current at 120 Hz and 8.82 A high-frequency ripple current at 10 kHz, supporting substantial AC ripple loading in power applications.
• Leakage & Loss — Specified leakage current of 2200 µA and a tangent of loss angle (tanδ) of 0.2 for controlled dissipation characteristics.
• Endurance — 5000 hours load life at 85°C when rated ripple current and DC bias are applied, enabling longer maintenance intervals in continuous-use systems.
• Operating Range — Rated to operate from −25°C to +85°C, suitable for a wide range of ambient conditions.
• Mounting & Package — Screw terminal radial can (φ51 × 85 mm length) for secure mechanical and electrical connections in chassis- or bracket-mounted power modules.
• Compliance — RoHS compliant for regulatory alignment in controlled-material assemblies.

Typical Applications

• Power supplies and DC link capacitors — Provides bulk energy storage and smoothing where 450 V rating and high ripple capability are required.
• Industrial power electronics — Suitable for general-purpose filtering and decoupling in industrial converters and control systems.
• High-voltage filtering — Use in circuits requiring polarized, high-voltage capacitance with secure screw-terminal connections for robust mounting.

Unique Advantages

• High ripple handling: 6.3 A (120 Hz) and 8.82 A (10 kHz) ripple ratings enable the capacitor to absorb substantial AC stress, reducing stress on upstream components.
• Long rated life: 5000 hours at 85°C under rated ripple and DC bias provides predictable durability for continuous-duty applications.
• Screw-terminal reliability: Radial can with screw terminals ensures secure electrical and mechanical connection for heavy-current and vibration-prone environments.
• Clear thermal specification: −25°C to +85°C operating range supports deployment across a broad set of ambient conditions.
• Regulatory alignment: RoHS compliance facilitates integration into assemblies requiring restricted-substance adherence.
