LGU2E331MELA

The LGU2E331MELA is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It delivers polarized bulk capacitance with a high rated voltage and engineered ripple-handling characteristics for industrial and commercial power designs.

Built to Nichicon's LGU series 105°C standard, this component combines a 250 V rating with long endurance and RoHS compliance to support reliable operation in equipment requiring sustained ripple current capability and extended life at elevated temperatures.

Key Features

• Rated Voltage and Capacitance — 250 V rated voltage with 330 µF capacitance and ±20% tolerance for stable bulk energy storage in high-voltage circuits.
• Low Loss (tan δ) — Tan δ specified at 0.15 (measurement at 120 Hz, 20°C) to help minimize dissipation in AC stress conditions typical of power systems.
• Ripple Current Capability — Handles 1.3 A at 120 Hz (low frequency) and 1.95 A at 50 kHz (high frequency), enabling effective suppression of voltage ripple across a range of operating frequencies.
• Leakage Current — Specified leakage current of 860 µA after rated voltage application, suitable for power applications where predictable leakage behavior is required.
• High-Temperature Endurance — 3000 hours life rating at 105°C under rated ripple and DC bias, offering extended durability in thermally demanding environments.
• Operating Temperature Range — –40°C to 105°C for use across broad ambient conditions.
• Package and Mounting — Radial, can-type snap-in package (φ25×30L) for secure board mounting and straightforward assembly; supplied in tray packing for mass production.
• Regulatory — RoHS compliant, meeting current directive requirements for hazardous substance restrictions.

Typical Applications

• General-Purpose Power Supplies — Bulk smoothing and energy storage in 250 V class power modules where sustained ripple handling and 105°C endurance are required.
• Industrial Power Electronics — Filtering and decoupling in industrial converters and control equipment that operate across a wide temperature range.
• Commercial Power Systems — Use in commercial UPS, power conditioners, and other systems requiring reliable high-voltage capacitance and long-life performance.

Unique Advantages

• High Voltage Handling: 250 V rating supports designs that require elevated DC bus voltages without the need for series stacking.
• Frequency-Resilient Ripple Performance: Specified ripple current at both low and high frequencies enables dependable ripple suppression across common switching and line frequencies.
• Long Endurance at Elevated Temperature: 3000 hours at 105°C under rated conditions provides demonstrable longevity for thermal-stressed installations.
• Predictable Electrical Behavior: Clear specifications for tan δ and leakage current aid in thermal budgeting and long-term leakage forecasts for product validation.
• Production-Friendly Packaging: Tray-packed, snap-in can format simplifies automated handling and repeatable assembly for high-volume manufacturing.
