LGGW6331MELB35

The LGGW6331MELB35 is a Nichicon LGG-series aluminum electrolytic capacitor in a snap-in, radial can package. It provides 330 µF capacitance at a 420 V rating with polarized terminals and tray packing for mass production assembly.

Engineered for general-purpose power applications, this part combines a compact φ30 × 35 mm footprint with a 105°C maximum operating temperature and a 2000-hour endurance rating at 105°C for reliable high-voltage smoothing and energy-storage use in industrial and power-conversion equipment.

Key Features

• Electrical Rating: 330 µF capacitance at 420 V nominal with ±20% tolerance, suitable for high-voltage DC smoothing and bulk energy storage.
• High-temperature Endurance: Rated for operation to 105°C with an endurance specification of 2000 hours at 105°C under DC bias plus rated ripple current.
• Compact, Snap-in Package: Radial, snap-in can in a φ30 × 35 mm package (L: 3.5 × D: 3 cm) designed for easier mounting in high-density power assemblies.
• Ripple Current Performance: Specified ripple current of 1.42 A at 120 Hz and 2.031 A at 100 kHz, supporting common power-supply ripple conditions.
• Loss and Leakage Characteristics: tan δ ≤ 0.15 (120 Hz, 20°C) for the 160–420 V range and leakage current limited by I ≤ 3√CV (μA) after 5 minutes at rated voltage.
• Low-temperature Stability: For rated voltages in the 400–450 V range, impedance ratio Z(–25°C)/Z(+20°C) is specified up to 8, supporting cold-start performance down to –25°C.
• Regulatory Compliance: RoHS compliant as part of the LGG series.

Typical Applications

• Industrial Power Supplies: Bulk smoothing and energy storage on 420 V DC rails where compact, high-voltage capacitors are required and operation up to 105°C is expected.
• Power Conversion and Inverters: DC-link and filtering duties in power converters and inverters that demand high-voltage capability and specified ripple handling at 120 Hz and higher frequencies.
• UPS and Energy-Storage Modules: Energy buffering and decoupling for standby power systems that benefit from the part’s 330 µF capacitance and 420 V rating.
• General-purpose High-voltage Filtering: Applications requiring polarized, snap-in mounting capacitors for reliable, serviceable bulk capacitance in compact assemblies.

Unique Advantages

• High-voltage capability: 420 V rating lets designers use a single capacitor for higher-voltage DC rails, reducing the need for series configurations.
• Compact footprint: φ30 × 35 mm snap-in can reduces board space compared with larger-form alternatives while retaining substantial capacitance.
• Designed for elevated temperatures: 105°C rating and 2000-hour endurance at 105°C provide predictable life under demanding thermal conditions.
• Measured ripple handling: Specified ripple currents at 120 Hz and 100 kHz allow straightforward selection for common switching and line-frequency environments.
• Controlled leakage and loss: Leakage limited by I ≤ 3√CV and tan δ ≤ 0.15 (for 160–420 V) support stable long-term electrical behavior and predictable dissipation.
• RoHS compliant: Meets RoHS directive requirements as part of the LGG series for environmentally restricted designs.
