LGG2G331MELB30

The LGG2G331MELB30 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for general-purpose electronic applications. It delivers 330µF capacitance at a 400V rated voltage with a 105°C maximum operating temperature and is supplied in tray packing for mass production.

Part of Nichicon’s LGG series, this snap-in terminal type offers a compact footprint (φ30 × 30 mm) and is RoHS compliant, addressing designs that require high-voltage capacitance in a reduced case size.

Key Features

• Capacitance & Voltage — 330 µF capacitance rated at 400 V for high-voltage applications requiring bulk energy storage.
• Tolerance — ±20% capacitance tolerance at 120 Hz, 20°C for predictable performance in validation and BOM planning.
• High-Temperature Rating — Rated for operation up to 105°C with specified endurance of 2000 hours at 105°C under rated conditions.
• Snap-in Radial Can Package — φ30 × 30 mm radial, snap-in can provides a compact form factor suitable for tray-packed, mass-production assembly.
• Leakage and Loss Characteristics — Leakage current specified per datasheet as I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ limits and impedance stability are provided in the LGG series data.
• Ripple Current Ratings — Rated ripple current: 1.15 A at 120 Hz (low frequency) and 1.645 A at 100 kHz (high frequency), enabling use where defined ripple handling is required.
• Series Benefits — LGG series noted as “105°C Ultra-Smaller-Sized” and one rank smaller case size than LGN, supporting equipment downsizing initiatives.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Suitable where a 400 V, 330 µF electrolytic capacitor is required for bulk capacitance in general-purpose designs.
• Equipment downsizing and compact power modules — Ultra-smaller-sized LGG series package helps reduce case footprint while retaining required capacitance and voltage rating.
• High-temperature operating environments — 105°C rating and 2000-hour endurance data make it appropriate for applications that demand sustained elevated-temperature performance.

Unique Advantages

• High-voltage capability: 400 V rating provides ample headroom for high-voltage circuits requiring bulk capacitance.
• Compact snap-in form: φ30 × 30 mm radial, snap-in can balances high capacitance with a smaller case size for board-space-constrained designs.
• Defined endurance: Endurance specified as 2000 hours at 105°C under rated conditions, giving designers quantifiable lifetime expectations.
• Measured ripple handling: Published ripple current values at 120 Hz and 100 kHz allow for straightforward thermal and ripple budgeting in power designs.
• Predictable leakage behavior: Leakage current specification (I ≤ 3√CV) provides a clear limit for leakage budgeting and qualification testing.
• Regulatory compliance: RoHS compliance supports use in regions and products requiring restricted-substance conformity.
