LLG2G471MELA50

The LLG2G471MELA50 is a snap-in, aluminum electrolytic capacitor from Nichicon’s LLG series, offering 470 µF capacitance at a 400 V rating. Designed as a smaller-sized snap-in solution within the LLG family, it targets general-purpose high-voltage applications where compact bulk capacitance and robust ripple handling are required.

With a 85°C endurance rating and a lifetime of 2000 hours at 85°C, plus RoHS compliance and tray packing for production handling, this part is positioned for equipment designs that demand reliable high-voltage energy storage and smoothing in a reduced footprint.

Key Features

• Core Capacitance and Voltage — 470 µF nominal capacitance rated at 400 V for high-voltage bulk energy storage and filtering.
• Snap-In Package — Radial can with snap-in terminals (φ25 × 50 mm) for secure chassis or PCB mounting and simplified assembly; available in tray packing for production environments.
• Ripple Current Capability — Handles 2.13 A at 120 Hz (low frequency) and 3.046 A at 100 kHz (high frequency), enabling effective smoothing under substantial AC ripple conditions.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) ≤ 0.15 measured at 20°C and 120 Hz; leakage current specified at 1300 µA, supporting predictable performance under DC bias.
• Temperature and Endurance — Rated for operation from −25°C to +85°C with an endurance life of 2000 hours at 85°C under D.C. bias plus rated ripple current.
• Polarized Electrolytic Design — Conventional polarized aluminum electrolytic construction for high capacitance per volume in power electronics applications.
• Regulatory Status — RoHS compliant, aligning with restricted substances requirements.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and decoupling in high-voltage supply rails where 470 µF at 400 V provides energy buffering and voltage stability.
• Power Conversion and Inverters — DC-link and energy storage in medium-power converters, benefiting from the part’s high ripple current capacity and 400 V rating.
• Control Cabinets and Stationary Equipment — Compact high-voltage filtering in equipment requiring reduced case size without sacrificing capacitance or endurance.

Unique Advantages

• High-Voltage Bulk Capacity: 470 µF at 400 V provides substantial capacitance for high-voltage filtering and energy storage in a single component.
• Robust Ripple Handling: Rated ripple currents of 2.13 A (120 Hz) and 3.046 A (100 kHz) support sustained AC stress and reduce the need for parallel components.
• Smaller Case Footprint: Part of the LLG series designed as a one-rank smaller case than comparable types, aiding equipment downsizing without losing capacitance.
• Predictable Loss and Leakage: Low tan δ (0.15 at 20°C, 120 Hz) and specified leakage current (1300 µA) enable predictable thermal and DC performance.
• Production-Ready Packaging: Tray packing and mass-production status simplify procurement and assembly for volume manufacturing.
• Designed for Endurance: 2000-hour life at 85°C under rated conditions supports reliability targets for long-run equipment operation.
