LNX2L472MSEJ

The LNX2L472MSEJ from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNX series, rated 4700 µF (4.7 mF) at 550 V. It is designed for extra-high-voltage applications where high ripple current capability and durable performance are required.

Typical applications include industrial power supplies and inverter circuitry where robust bulk capacitance, secure screw-terminal connections, and long endurance under rated ripple conditions are important.

Key Features

• High Voltage Rating — Rated for 550 V to support extra‑high‑voltage power circuitry.
• Large Capacitance — 4700 µF (4.7 mF) nominal capacitance with ±20% tolerance for energy storage and bulk filtering.
• High Ripple Current Capability — Rated ripple current of 14.5 A at 120 Hz and 20.3 A at 100 kHz to handle demanding AC ripple in power converters.
• Long Endurance at Elevated Temperature — Specified endurance for the 500 V and 550 V rated parts: performance maintained after 5000 hours under DC bias plus rated ripple current at +85°C.
• Robust Screw-Terminal Package — Radial can with screw terminals for secure, low-impedance connections and easy mounting in power racks and assemblies; package dimensions L: 17 × D: 9 cm and height seated max 6.693 inch.
• Operating Temperature Range — −25 °C to +85 °C to match common industrial ambient conditions.
• Safety and Environmental — Flame-retardant electrolyte type available; RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk energy storage and filtering in high-voltage industrial supplies, including inverter front ends and DC link circuits.
• Inverter Circuitry — Supports inverter DC-link and smoothing stages where high voltage and high ripple handling are required.
• High‑Ripple Power Converters — Suitable for power converter stages that demand sustained ripple current capability at both low and high frequencies.

Unique Advantages

• Extra‑High Voltage Capacity: 550 V rating enables use in circuits requiring elevated DC bus voltages without series stacking.
• High Ripple Endurance: Specified ripple current ratings at 120 Hz and 100 kHz reduce thermal stress and support reliable operation in converters.
• Engineered for Long Service Life: Endurance validated for 5000 hours at +85 °C under DC bias plus rated ripple current for 500 V/550 V parts, supporting predictable maintenance intervals.
• Screw-Terminal Reliability: Radial can with screw terminals provides secure mechanical and electrical connections for industrial assemblies.
• Regulatory Compliance: RoHS compliance and availability of a flame-retardant electrolyte option support environmental and safety goals.
