LLS2G331MELA

The LLS2G331MELA is a Nichicon LLS series aluminum electrolytic capacitor in a snap-in terminal package, rated 400 V with 330 µF nominal capacitance and ±20% tolerance. It is designed for general-purpose power applications that require high-voltage capacitance in a robust, snap-in can.

Key value comes from its high ripple-current capability, long 3,000-hour endurance at 85°C, low dissipation factor, and RoHS compliance—features that support reliable performance in industrial and power-electronics environments.

Key Features

• High Voltage Rating — 400 V rated voltage suitable for high-voltage power rails and bulk energy storage in general-purpose designs.
• Capacitance and Tolerance — 330 µF nominal with ±20% tolerance for stable bulk capacitance in filtering and smoothing applications.
• Ripple Current Performance — Supports 2.0 A ripple current at 120 Hz (low frequency) and 2.86 A at 50 kHz (high frequency), enabling effective ripple handling across common switching and line frequencies.
• Low Dissipation Factor — tanδ of 0.15 (measured at 20°C, 120 Hz) for efficient operation and reduced heating under AC ripple.
• Long Endurance — 3,000 hours rated life at 85°C with specified endurance criteria for capacitance, tanδ and leakage current.
• Leakage Current — Specified leakage current of 1080 µA, providing predictable DC behavior after voltage application.
• Snap-in, Radial Can Package — φ25 × 45 L form factor (L: 4.5 × D: 2.5 cm) with snap-in terminals for secure mechanical mounting and ease of assembly.
• Environmental Compliance & Packaging — RoHS compliant and supplied in tray packing for production-level handling.

Typical Applications

• General-purpose power systems — Designed for applications requiring 400 V rated capacitance and reliable endurance at elevated temperatures.
• Power supply filtering — Bulk smoothing and ripple suppression where high ripple-current capability and low tanδ improve thermal behavior.
• Industrial electronics — Fits general-purpose industrial control and power conversion modules that demand long-life electrolytic capacitance.

Unique Advantages

• High-voltage capability: 400 V rating enables use on higher-voltage rails without additional series stacking.
• Robust ripple handling: 2.0 A at 120 Hz and 2.86 A at 50 kHz ripple-current ratings reduce stress on downstream circuitry and support switching-frequency applications.
• Predictable thermal performance: Low tanδ (0.15 at 20°C, 120 Hz) helps limit internal heating under AC conditions.
• Durability at elevated temperature: 3,000-hour endurance at 85°C provides long-term stability for sustained thermal environments.
• Production-ready packaging: Tray packing supports efficient handling and assembly in mass-production environments.
• Regulatory compliance: RoHS compliant for markets and designs requiring restricted-substance conformity.
