LGU2W331MELC

The LGU2W331MELC is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in, radial can package. It delivers 330 µF capacitance at a 450 V rating and is specified for general‑purpose applications that require high voltage handling and elevated temperature endurance.

Key electrical characteristics include a 450 V rated voltage, 330 µF capacitance with ±20% tolerance, low‑frequency and high‑frequency ripple current ratings, and a guaranteed endurance of 3000 hours at 105°C. The part is RoHS compliant and supplied in tray packing for production use.

Key Features

• High Voltage Rating — 450 V rated voltage suitable for applications requiring elevated DC working voltage.
• Capacitance and Tolerance — 330 µF nominal capacitance with a tolerance of −20% to +20% measured at 120 Hz, 20°C.
• Temperature and Endurance — Rated for operation from −25°C to +105°C with endurance of 3000 hours at 105°C when subjected to rated ripple current.
• Ripple Current Capability — Low‑frequency ripple current 1.45 A (120 Hz) and high‑frequency ripple current 2.074 A (50 kHz), with frequency coefficients defined in the LGU series datasheet.
• Loss and Leakage — Dissipation factor (tan δ) 0.2 (measured at 120 Hz, 20°C) and measured leakage current of 1150 µA.
• Package and Mounting — Snap‑in terminal (radial, can) construction in a φ35 × 40 mm can; supplied in tray packing for automated or manual assembly.
• Regulatory Compliance — Compliant with RoHS directives as stated for the LGU series.

Typical Applications

• General‑Purpose Electronics — Suitable for general‑purpose circuits that require a 450 V, 330 µF electrolytic capacitor with robust thermal endurance.
• Power Supply Filtering — Used where high DC voltage and sustained ripple current handling are required; specified ripple current and tan δ allow designers to size components against thermal and life requirements.
• Industrial Equipment — Appropriate for industrial applications needing a snap‑in, high‑voltage capacitor rated for extended operation at 105°C.

Unique Advantages

• High‑Voltage Capability: 450 V rating enables use in higher DC bus and filter applications without exceeding the part’s rated voltage.
• Long Endurance at Elevated Temperature: Specified for 3000 hours at 105°C under rated ripple current, supporting designs that require sustained thermal reliability.
• Measured Ripple Performance: Published low‑ and high‑frequency ripple current values (1.45 A @120 Hz, 2.074 A @50 kHz) allow accurate thermal and lifetime calculations.
• Clear Electrical Parameters: Defined tan δ (0.2 at 120 Hz, 20°C) and leakage current (1150 µA) provide precise parameters for circuit modeling and validation.
• Tray Packaging for Production: Supplied in tray packing to facilitate handling and assembly in production environments.
• RoHS Compliance: Conforms to RoHS directives as noted for the LGU series, supporting regulatory requirements.
