LGU2D331MELZ

The LGU2D331MELZ is a Nichicon LGU series snap-in aluminum electrolytic capacitor rated at 330 µF and 200 V. Designed for general-purpose power applications, it combines a compact φ22×30 mm can and snap-in terminals for secure mounting in high-voltage assemblies.

This part delivers engineered reliability with a 3000-hour endurance at 105°C, RoHS compliance, and defined electrical characteristics including low-loss tanδ, specified ripple current ratings, and low leakage current for stable performance in demanding operating environments.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-Temperature Endurance — Specified for 3000 hours at 105°C when subjected to DC bias plus rated ripple current, with capacitance change within ±20% and leakage current remaining within initial specified limits after the test.
• Ripple Current Performance — 1.25 A low-frequency ripple current at 120 Hz and 1.875 A high-frequency ripple current at 50 kHz (frequency coefficients apply per LGU series data).
• Low Loss — Tangent of loss angle (tan δ) of 0.15 maximum at 120 Hz and 20°C for the 160–420 V rated voltage category; the LGU series measurement criteria apply.
• Leakage Current — Specified leakage current of 770 µA (after 5 minutes’ application of rated voltage at 20°C as per datasheet conditions).
• Mounting & Package — Snap-in terminal type in a radial can package (φ22×30 mm), supplied in tray packing suitable for production use.
• Operating Range & Compliance — Operates from −40°C to +105°C and is RoHS compliant.

Typical Applications

• General-purpose power systems — Use where a 200 V, 330 µF snap-in electrolytic capacitor is required for bulk storage and smoothing in high-voltage assemblies.
• Industrial electronics — Suited for equipment that needs sustained operation at elevated temperatures up to 105°C with defined long-term endurance.
• High-voltage assemblies with snap-in mounting — Ideal for designs that prefer radial, can-type capacitors with secure snap-in terminals and tray packing for production runs.

Unique Advantages

• High-voltage capacity in a compact can — 200 V rating combined with 330 µF capacitance provides significant energy storage in a φ22×30 mm footprint.
• Long endurance at elevated temperature — 3000 hours at 105°C under rated ripple and DC bias ensures predictable aging and lifecycle behavior in hot environments.
• Defined ripple and loss characteristics — Specified ripple current values and a measured tanδ limit give engineers quantifiable thermal and AC performance parameters for design validation.
• Low leakage for predictable DC behavior — Specified leakage current supports stable bias characteristics after application of rated voltage.
• Production-ready packaging — Tray packing and mass production status streamline procurement and assembly for volume manufacturing.
• RoHS compliant — Meets RoHS directive requirements for environmental compliance in modern electronic designs.
