LGUW6471MELC

The LGUW6471MELC from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series, optimized for high‑voltage, general‑purpose power applications. It delivers 470 µF capacitance at a 420 V rating with a 105°C endurance profile and snap‑in mounting for robust panel and chassis integration.

Designed for applications that require sustained ripple handling and long service life, this capacitor combines high ripple current capability, low loss (tanδ), and a 3000‑hour endurance at 105°C to support reliable power filtering and energy smoothing in demanding environments.

Key Features

• Rated Performance — 470 µF capacitance with a 420 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• High‑Temperature Endurance — Rated for 3000 hours at 105°C when operated under DC bias plus rated ripple current, meeting LGU series endurance criteria.
• Low Loss (tanδ) — tanδ specified at 0.15 maximum for 160–420 V range (measured at 120 Hz, 20°C), supporting efficient energy handling.
• High Ripple Current Capacity — 1900 mA at 120 Hz (low frequency) and 2717 mA at 50 kHz (high frequency) to support smoothing and decoupling under dynamic loads.
• Leakage Current — Specified leakage current of 1330 µA after application of rated voltage, enabling predictable performance in DC circuits.
• Snap‑in Mounting, Radial Can — Snap‑in terminal type and radial can package simplify PCB and chassis assembly for high‑voltage power modules; tray packing suitable for mass production.
• Operating Temperature Range — Specified for −25°C to +105°C (applicable to the 315–450 V rated range in LGU series specification).
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and ripple reduction in high‑voltage DC power supplies and power conversion stages, leveraging the 420 V rating and high ripple current capability.
• Energy storage and DC link — Decoupling and energy buffering in converters where sustained ripple endurance at 105°C and 3000‑hour life are required.
• Industrial power systems — Use in industrial power modules and control equipment that demand high voltage handling and long operational lifetime under elevated temperatures.

Unique Advantages

• High‑voltage capability: 420 V rating enables deployment in higher‑voltage DC systems without the need for series stacking.
• Long endurance at elevated temperature: 3000‑hour rating at 105°C supports reliable operation in thermally stressful environments and reduces maintenance frequency.
• Robust ripple handling: Dual ripple current specifications (1.9 A at 120 Hz and 2.717 A at 50 kHz) provide clear guidance for both low‑ and high‑frequency ripple scenarios.
• Predictable electrical behavior: Low tanδ (0.15 max at 120 Hz, 20°C) and specified leakage current enable accurate design margins for power electronics.
• Assembly‑friendly package: Snap‑in radial can design with tray packing supports efficient mass production and secure mounting in power assemblies.
• Regulatory compliance: RoHS‑compliant construction aligns with modern environmental requirements.
