LNU2G472MSEGBB

The LNU2G472MSEGBB is an aluminum electrolytic capacitor in a screw‑terminal radial can designed for high‑voltage industrial power electronics. It delivers 4.7 mF capacitance at a 400 V DC rating and is part of Nichicon’s LNU series optimized for inverter and regenerative power applications.

Engineered for demanding environments, this screw‑terminal device supports high ripple currents and fast charge‑discharge cycles while operating across a −40°C to +105°C temperature range, with a rated load life of 5000 hours at 105°C.

Key Features

• Capacitance & Voltage — 4.7 mF capacitance with a 400 V DC rated voltage suitable for high‑voltage power circuits.
• High‑Temperature Endurance — Rated for operation from −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple current.
• Screw Terminal Mounting — Radial can package with screw terminals for secure, low‑impedance connections in industrial assemblies.
• High Ripple Current Capability — 16.1 A at 120 Hz and 22.54 A at 100 kHz, supporting heavy AC ripple and high‑frequency operation.
• Charge‑Discharge Durability — Designed to withstand high‑speed charge/discharge loading; series endurance specification includes charge‑discharge testing up to 50 million cycles (ΔV = rated voltage ±0.3, 3 Hz).
• Electrical Reliability — Leakage current and tan δ performance defined per datasheet; insulation resistance and voltage proof characteristics specified for robust insulation between terminal and bracket.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverter Power Supplies — Bulk energy storage and filtering in inverter front ends where high voltage and thermal endurance are required.
• AC Servomotor Regenerative Circuits — Handles high‑frequency regenerative voltages and supports rapid charge/discharge cycles in motor drive systems.
• General Inverters — Energy buffering and ripple current handling for grid‑tie or standalone inverter modules.
• High‑Frequency Power Electronics — Suitable where high ripple current at elevated frequencies (e.g., 100 kHz) is present.

Unique Advantages

• High‑voltage capability: 400 V DC rating (series rated up to DC525 V) enables use in higher‑voltage power stages without multiple smaller capacitors.
• Compact high‑voltage form factor: Smaller sized than comparable series options, helping reduce board space while maintaining required capacitance.
• Designed for rigorous thermal environments: −40°C to +105°C operating range and 5000‑hour life at 105°C provide predictable performance in hot industrial applications.
• Robust ripple handling: Specified ripple current at both low and high frequencies supports heavy AC loading and helps minimize temperature rise during operation.
• Durable under repetitive cycling: Endurance validated for extensive charge‑discharge cycles, addressing regenerative and pulsed power use cases.
• RoHS compliant: Conforms to current RoHS requirements for regulatory and environmental consistency.
