LGU2G561MELC

The LGU2G561MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series. It delivers 560 µF capacitance at a 400 V rating in a radial, can-style snap-in package sized φ35×45 mm.

Designed for general-purpose power applications, this capacitor combines high-voltage capability with proven endurance and defined ripple-handling performance to support 400 V system designs that require bulk storage and ripple suppression within a compact footprint.

Key Features

• Rated Capacitance & Voltage — 560 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• High Temperature Endurance — Qualified for 3000 hours at 105 °C under DC bias plus rated ripple current as specified for the LGU series.
• Ripple Current Performance — Low-frequency ripple current 2.120 A at 120 Hz and high-frequency ripple current 3.032 A at 50 kHz to address both mains-frequency and higher-frequency converter ripple.
• Leakage & Dissipation — Specified leakage current of 1410 µA and tan δ (DF) of 0.15 at 20 °C, 120 Hz for the 400 V rating, enabling predictable loss and self-heating behaviour.
• Mounting & Package — Snap-in terminal, radial can package (φ35×45 mm) for secure mechanical retention and efficient PCB assembly in vertical configurations.
• Regulatory — RoHS compliant per the LGU series declaration.

Typical Applications

• Power supply bulk smoothing — 400 V rating and 560 µF capacitance provide energy storage and voltage stabilization in high-voltage DC rails.
• Ripple filtering in converters — Specified ripple current at 120 Hz and 50 kHz supports both low- and high-frequency ripple suppression for power converters.
• Industrial power systems — Endurance of 3000 hours at 105 °C under rated conditions helps meet reliability needs in industrial power electronics.

Unique Advantages

• High-voltage capability: 400 V rating enables use in elevated DC bus and high-voltage power rails without requiring parallel parts.
• Verified ripple endurance: Rated ripple current values and 3000 hr endurance at 105 °C provide predictable long-term performance under continuous ripple stress.
• Compact snap-in form factor: φ35×45 mm radial can with snap-in terminals simplifies board layout and mechanical retention for vertical mounting.
• Controlled electrical loss: tan δ of 0.15 at 20 °C, 120 Hz and specified leakage current support thermal planning and system loss calculations.
• Production-ready packaging: Tray packing and mass-production availability support volume assembly workflows and procurement planning.
• RoHS compliance: Conforms to RoHS directives as specified for the LGU series.
