LNK2W472MSEH

The LNK2W472MSEH from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNK series, engineered for general-purpose power applications that require high capacitance at elevated voltages. This radial can, screw-terminal device combines 4.7 mF capacitance with a 450 V rating and is offered in a φ76.2 × 115 mm package for systems where robust, high-voltage bulk capacitance is needed.

Designed for mass production and shipped in cardboard packing, the LNK2W472MSEH emphasizes reliability with a rated lifetime of 5000 hours at 85°C and RoHS compliance for environmental consistency.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 µF) nominal capacitance with a 450 V rated voltage, suited to high-voltage bulk energy applications.
• Tolerance & Polarization — ±20% capacitance tolerance and polarized construction for predictable storage behavior in DC circuits.
• Mounting & Package — Screw terminal radial can package with screw terminals for secure, low-resistance connections in chassis-mounted or bracketed assemblies.
• Mechanical Dimensions — Physical size φ76.2 × 115 mm (L: 11.5 cm × D: 7.62 cm) to aid mechanical integration and bracket mounting.
• Temperature & Lifetime — Rated operating range −25°C to +85°C with a load life of 5000 hours at 85°C under rated ripple conditions.
• Loss, Leakage & Ripple Performance — Specified tangent of loss angle (tan δ) 0.2 and a documented leakage current value of 4360 µA; ripple current ratings include 15.1 A at 120 Hz and 21.14 A at 10 kHz.
• Regulatory — RoHS compliant to support environmental and material requirements.

Typical Applications

• General purpose power systems — Suited for applications that require high-voltage bulk capacitance and secure screw-terminal connections.
• Industrial electronics — Fits assemblies where a durable, high-capacitance, high-voltage polarized capacitor is needed for energy buffering and smoothing.
• Commercial equipment — Appropriate for equipment designs that call for long-life (5000 h at 85°C) electrolytic capacitors with robust mechanical mounting.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage DC circuits without stacking multiple lower-voltage parts.
• Large capacitance in a compact radial can: 4.7 mF provides substantial bulk capacitance while maintaining a defined mechanical footprint (φ76.2 × 115 mm).
• Secure screw-terminal mounting: Screw terminals provide reliable electrical and mechanical connection for chassis- or bracket-mounted installations.
• Documented ripple and leakage specs: Ripple current figures at 120 Hz and 10 kHz, along with a specified leakage current, support thermal and electrical budgeting during design.
• Longevity at elevated temperature: 5000 hours rated life at 85°C helps support durability expectations in continuous-duty applications.
• RoHS compliance: Meets RoHS directives for material restrictions, simplifying environmental compliance for end products.
