LGU2G471MELB

The LGU2G471MELB is a Nichicon LGU‑series snap‑in aluminum electrolytic capacitor specified at 470 µF and 400 V. It is a polarization type, designed for general‑purpose applications that require high‑voltage bulk capacitance with snap‑in mounting for secure board retention.

Key value comes from its 105 °C design and endurance—able to withstand rated ripple current at elevated temperature—combined with radial snap‑in packaging and tray packing for assembly environments that need durable, high‑voltage capacitors.

Key Features

• Electrical Capacity — 470 µF nominal capacitance with a tolerance of ±20% at 120 Hz, 20 °C, providing defined bulk energy storage for DC circuits.
• High Voltage Rating — Rated at 400 V DC, suitable wherever a 400 V polarized aluminum electrolytic is required.
• Loss Characteristics — tanδ (DF) 0.15 measured at 20 °C, 120 Hz, indicating specified dissipation factor for AC and ripple conditions.
• Ripple Current Handling — Low‑frequency ripple current 1.900 A (120 Hz) and high‑frequency ripple current 2.717 A (50 kHz) for robust performance under AC ripple loads.
• Leakage Current — Specified leakage current of 1,300 µA after rated voltage application, enabling predictable leakage behavior in designs.
• High‑Temperature Endurance — Designed for 3,000 hours of endurance at 105 °C with rated ripple current applied, per LGU series specification.
• Operating Temperature Range — Rated to operate from −25 °C to +105 °C for the 315–450 V range, matching the part’s 400 V rating.
• Mechanical & Packaging — φ30 × 50 mm can (radial, snap‑in) with snap‑in terminals for secure PCB mounting; supplied in tray packing for handling and assembly.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863) as specified for the LGU series.

Typical Applications

• General‑purpose high‑voltage circuits — Use where a 400 V, 470 µF polarized snap‑in capacitor is required for bulk energy storage and DC smoothing within the specified temperature and endurance limits.
• Power supply filtering — Provides bulk capacitance and ripple handling (1.9 A @120 Hz; 2.717 A @50 kHz) for power supplies operating up to 105 °C.
• Industrial electronics — Suitable for general‑purpose industrial boards that require secure snap‑in mounting and long endurance at elevated temperature (3,000 h at 105 °C).

Unique Advantages

• Long high‑temperature endurance: 3,000‑hour rating at 105 °C under rated ripple current provides predictable lifetime performance in thermally demanding installations.
• High voltage capability: 400 V rating delivers high DC voltage margin for designs needing elevated bus voltages with substantial capacitance.
• Defined ripple performance: Specified ripple currents at both low and high frequencies allow designers to size capacitors against real ripple loads.
• Secure board retention: Snap‑in terminal package offers reliable mechanical retention for radial mount applications and through‑hole assembly processes.
• RoHS compliance: Meets RoHS directive requirements for materials, supporting regulatory needs for electronics assemblies.
• Assembly‑friendly packaging: Tray packing facilitates handling and placement in production environments.
