LGUW6331MELC

The LGUW6331MELC is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in terminal package. It provides 330 µF capacitance at a 420 V rating and is specified for general-purpose applications that require high-voltage energy storage and ripple handling.

Designed for continuous operation up to 105°C with a rated endurance of 3000 hours, this snap-in can supports elevated ripple currents and is supplied in tray packing for production assembly.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance for high-voltage energy storage.
• High-temperature Endurance — Rated life of 3000 hours at 105°C when subjected to rated ripple current and D.C. bias, supporting long-term operation in hot environments.
• Ripple Current Capability — Low-frequency ripple current of 1.45 A at 120 Hz and high-frequency ripple current of 2.074 A at 50 kHz, enabling effective smoothing under varying load frequencies.
• Leakage and Dissipation — Specified leakage current of 1110 µA and a tangent of loss angle (tan δ) of 0.15 (measured at 20°C, 120 Hz, for the 160–420 V range), useful for thermal and loss budgeting.
• Operating Temperature Range — −25°C to +105°C operating range, suitable where elevated ambient temperatures are expected within the stated limits.
• Snap-In Radial Can Package — φ35 × 35L size in a snap-in can (radial) for robust board retention and automated assembly; supplied in tray packing for production handling.
• RoHS Compliant — Meets RoHS requirements as stated for the LGU series.

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and smoothing in circuits that require 420 V rated capacitors with substantial ripple handling.
• High-temperature environments — Suited to applications operating up to 105°C where 3000-hour endurance at elevated temperature is required.
• High-voltage energy storage — Useful where a compact 330 µF, 420 V capacitor in a snap-in can is needed for energy buffering or decoupling.

Unique Advantages

• High voltage rating: 420 V rating enables use in designs requiring elevated DC bus or energy storage voltage without series stacking.
• Long rated life at 105°C: 3000-hour endurance under rated ripple and bias reduces the need for frequent component replacement in hot operating conditions.
• Substantial ripple handling: Specified low- and high-frequency ripple current values allow designers to account for thermal rise and ripple stress across a range of operating frequencies.
• Measured loss characteristics: tan δ of 0.15 (20°C, 120 Hz) and specified leakage current provide measurable parameters for power-loss and leakage budgeting in designs.
• Production-friendly packaging: Snap-in radial can and tray packing simplify board assembly and mechanical retention for higher-volume manufacturing.
• Regulatory compliance: RoHS-compliant construction supports regulatory requirements for electronic assemblies.
