LNK2W472MSEG

The LNK2W472MSEG from Nichicon is a screw‑terminal aluminum electrolytic capacitor in the LNK series, specified for high‑voltage, high‑ripple applications. It delivers 4700 µF capacitance at a 450 V rating with a polarized radial can and screw terminal mounting.

Designed for general‑purpose use, this capacitor combines a wide operating temperature range (−25 °C to +85 °C), a 5000‑hour load life at 85 °C under rated ripple conditions, and RoHS compliance to support reliable energy storage and ripple handling in high‑voltage assemblies.

Key Features

• High Capacitance and Voltage — 4700 µF nominal capacitance with a 450 V rating provides substantial bulk energy storage for high‑voltage systems.
• Screw Terminal Package — Radial can with screw terminals simplifies secure mechanical and electrical connections in chassis‑mounted or bracketed installations.
• High Ripple Current Capability — Rated ripple current of 15.6 A at 120 Hz and 21.84 A at 10 kHz supports heavy AC ripple and switching currents.
• Temperature and Lifetime — Operating range −25 °C to +85 °C and endurance of 5000 hours at 85 °C when subjected to DC bias plus rated ripple current.
• Reliability Specifications — Leakage current limited to 3√(C·V) μA or 5 mA (whichever is smaller) after 5 minutes at rated voltage; insulation resistance >100 MΩ at DC 500 V between terminal and bracket; AC 2500 V voltage proof for 1 minute between terminal and bracket.
• Manufacturing and Compliance — Part of Nichicon’s LNK series with RoHS compliance and white printing on black sleeve marking for clear identification.

Typical Applications

• High‑Voltage Power Modules — Bulk energy storage and ripple handling where 450 V ratings and high ripple currents are required.
• Industrial Power Supplies — Filtering and smoothing under sustained ripple conditions, supported by a 5000‑hour endurance rating at 85 °C.
• Chassis‑Mounted Systems — Screw terminal radial can enables robust mounting and secure electrical connections in cabinet or bracketed assemblies.

Unique Advantages

• High Energy Density at 450 V: Provides substantial capacitance (4700 µF) for applications that demand elevated DC bus voltages.
• Engineered for Ripple Endurance: Specified ripple current values at both low and high frequencies help designers size capacitors for switching and line‑frequency ripple profiles.
• Long Operational Life at Elevated Temperature: 5000 hours at 85 °C under rated conditions supports predictable long‑term performance in thermal environments.
• Robust Electrical Safety Margins: Insulation resistance and voltage‑proof test values reduce the risk of terminal‑to‑bracket failures in high‑voltage assemblies.
• Easy Integration into Mechanical Designs: Screw terminal and radial can package simplify mounting and wiring in rack, cabinet, and chassis installations.
