LGG2G471MELC30

The LGG2G471MELC30 is a Nichicon LGG series snap‑in aluminum electrolytic capacitor rated at 470 µF and 400 V with ±20% tolerance. It combines high capacitance and high‑voltage handling in a compact, snap‑in radial can intended for power and industrial assemblies.

Designed for sustained operation up to 105°C with 2000 hours endurance, this part targets bulk energy storage and smoothing in high‑voltage power electronics where robust ripple handling and compact packaging are required.

Key Features

• High Voltage Rating — 400 V rated voltage suitable for 400 V DC bus and other high‑voltage applications.
• Large Capacitance — 470 µF nominal capacitance with ±20% tolerance for effective bulk energy storage and decoupling.
• Thermal Endurance — Rated for operation from −25°C to 105°C with 2000 h endurance at 105°C under rated DC bias plus ripple current.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.15 max (measured at 20°C, 120 Hz), minimizing dissipation at line frequency.
• High Ripple Current Capability — 1550 mA at 120 Hz (low frequency) and 2216.5 mA at 100 kHz (high frequency) for effective smoothing under heavy ripple conditions.
• Leakage Current — Leakage current specified at 1300 µA, enabling predictable bias behavior after charge.
• Snap‑in Radial Can — Snap‑in mounting provides secure mechanical retention for power module and chassis installations; compact φ35 × 30 mm case supports equipment downsizing.
• RoHS Compliant — Conforms to RoHS requirements for lead‑free assemblies.

Typical Applications

• Power Supplies — Bulk filtering and DC link smoothing on 400 V rails where high capacitance and ripple handling are required.
• Industrial Inverters and Drives — Energy storage and ripple suppression in inverter DC buses and motor drive front ends operating at elevated temperatures.
• Power Conversion Modules — Decoupling and bulk capacitance in compact power modules and mid‑plane assemblies using snap‑in mounting for mechanical stability.
• Renewable and Energy Storage Systems — High‑voltage smoothing for battery or PV inverter electronics requiring sustained operation at up to 105°C.

Unique Advantages

• High‑voltage bulk in a compact case: 470 µF at 400 V provides substantial energy storage while the φ35 × 30 mm can supports space‑constrained designs.
• Designed for sustained high‑temperature use: 2000 hours endurance at 105°C ensures predictable life under elevated operating temperatures and continuous DC bias.
• Robust ripple performance: Specified ripple currents at both 120 Hz and 100 kHz accommodate a range of switching and line‑frequency ripple profiles.
• Low dissipation at line frequency: tan δ of 0.15 (120 Hz, 20°C) reduces losses in AC‑coupled smoothing applications.
• Secure mechanical mounting: Snap‑in terminals simplify assembly and provide stable retention in power enclosures and modules.
• Series packaging and production: Tray packing and mass production status support volume procurement and assembly flow.
