LLG2G471MELC30

The LLG2G471MELC30 is a Nichicon LLG series aluminum electrolytic capacitor in a snap-in terminal configuration. It delivers 470 µF capacitance at a 400 V rating in a compact φ35 × 30 mm can designed for tray packing and mass production.

Engineered for general-purpose power electronics, this snap-in capacitor combines high-voltage capability, substantial bulk capacitance and an endurance rating suitable for applications requiring reliable DC filtering and energy storage within a limited footprint.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 400 V for bulk energy storage and smoothing in high-voltage circuits.
• Snap-in Mounting — Radial can with snap-in terminals for secure, high-reliability board mounting in mass-production assemblies.
• Compact LLG Series Size — φ35 × 30 mm can size (smaller-sized LLG series) suited for equipment downsizing while maintaining required capacitance.
• Operating Temperature & Endurance — Rated for operation from −25 °C to +85 °C with an endurance of 2000 hours at 85 °C under specified conditions.
• Ripple Handling — Specified ripple current capability including 2.13 A at 120 Hz and 3.046 A at 100 kHz to support both low- and high-frequency ripple environments.
• Polarized Electrolytic — Polarized design with capacitance tolerance of −20% to +20% and leakage characteristics per series specifications.
• RoHS Compliant — Compliant with RoHS directives as noted for the LLG series.

Typical Applications

• General-purpose power electronics — Bulk smoothing and DC link filtering where a 400 V, 470 µF polarized capacitor is required.
• Industrial power supplies — Energy storage and ripple reduction in general-purpose industrial converters and power modules.
• Equipment downsizing projects — Compact φ35 × 30 mm LLG series sizing enables reduced system footprint while retaining capacitance for high-voltage designs.
• Mass-production assemblies — Snap-in terminal and tray packing format streamline automated assembly for production-scale builds.

Unique Advantages

• High-voltage capability: 400 V rating supports applications requiring elevated DC bus voltages without additional series components.
• Significant bulk capacitance: 470 µF provides substantial energy storage for smoothing and decoupling in power circuits.
• Compact snap-in package: φ35 × 30 mm can with snap-in terminals supports secure, space-efficient PCB integration and assembly throughput.
• Durability under rated conditions: 2000-hour endurance at 85 °C provides predictable performance over extended thermal stress when used within specified limits.
• Wide ripple frequency support: Specified ripple current at both 120 Hz and 100 kHz addresses AC ripple across a range of switching frequencies.
• Regulatory compliance: RoHS compliance supports integration into designs targeting restricted-substance requirements.
