LLG2G331MELB30

The LLG2G331MELB30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LLG series, offering 330 µF capacitance at a 400 V rating in a compact φ30 × 30 mm can. It is a smaller-sized snap-in solution designed for general-purpose use and is suited for equipment downsizing where a high-voltage, compact electrolytic is required.

Designed for production environments, this part is supplied in tray packing for mass production and is RoHS compliant.

Key Features

• Capacitance & Voltage — Rated at 330 µF with a 400 V DC voltage rating and ±20% tolerance.
• Compact Snap-in Package — Radial, can-type snap-in construction in a φ30 × 30 mm size; one rank smaller case than LLS to support equipment downsizing.
• Operating Temperature & Endurance — Specified operating temperature range of −25 °C to +85 °C for 400–450 V parts and an endurance of 2000 hours at 85 °C under rated conditions.
• Ripple Current Performance — Rated ripple current of 1.7 A at 120 Hz (low frequency) and 2.431 A at 100 kHz (high frequency).
• Electrical Characteristics — Leakage current defined by I ≤ 3√(C·V) μA after 5 minutes at 20 °C; tangent of loss angle (tan δ) max 0.15 at 120 Hz for 160–400 V ratings.
• Low-temperature Stability — For 400 V parts, impedance ratio Z(−25 °C)/Z(+20 °C) up to 8 at 120 Hz.
• Polarized, Marking & Compliance — Polarized electrolytic with white-on-black sleeve marking and RoHS compliance.

Typical Applications

• General Purpose — Intended for general-purpose designs requiring 330 µF capacitance and a 400 V rating.
• Compact Equipment — One-rank-smaller case size makes this part suitable where equipment downsizing is a priority.
• Mass-production Assemblies — Supplied in tray packing to support high-volume manufacturing and assembly workflows.

Unique Advantages

• Space-saving form factor: One rank smaller case than LLS enables reduced PCB footprint and overall equipment size.
• High-voltage capacity: 330 µF at 400 V provides substantial stored energy in a compact snap-in can.
• Robust ripple handling: Defined ripple current ratings (1.7 A at 120 Hz and 2.431 A at 100 kHz) support AC stress within specified limits.
• Proven endurance at elevated temperature: Rated 2000 hours at 85 °C under DC bias plus rated ripple current, with specified post-test capacitance, tan δ, and leakage requirements.
• Measurable electrical limits: Leakage current specification (I ≤ 3√CV μA after 5 minutes at 20 °C) and tan δ max 0.15 at 120 Hz give clear acceptance criteria for designs and testing.
• Production-ready packaging and compliance: Tray packing for mass production and RoHS compliance simplify procurement and regulatory alignment.
