LGU2G221MELC

The LGU2G221MELC is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in, radial can package rated for 400 V and 220 µF. Designed for general‑purpose power applications, it delivers high-voltage capacitance with industry‑standard snap‑in mounting and tray packing for production assembly.

Key reliability attributes include a −25°C to 105°C operating range (applicable for 315–450 V parts), 3,000 hours endurance at 105°C under rated ripple conditions, and RoHS compliance. The part is in mass production.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑temperature Endurance — Rated for 3,000 hours at 105°C when DC bias plus rated ripple current is applied; meets the LGU series endurance criteria.
• Ripple Current Performance — Low‑frequency ripple current 1.1 A at 120 Hz and high‑frequency ripple current 1.573 A at 50 kHz, enabling effective handling of AC ripple across frequency ranges.
• Low Loss — tan δ of 0.15 (measured at 120 Hz, 20°C) appropriate for the 160–420 V category, supporting stable impedance characteristics.
• Leakage Current — Specified leakage current of 880 µA (measured after application of rated voltage at 20°C).
• Package & Mounting — Radial, snap‑in can (φ35 × 25L mm) for secure through‑hole retention in power assemblies; provided in tray packing for production handling.
• Environmental Compliance — RoHS compliant per product information.

Typical Applications

• General Purpose — Provides 220 µF at 400 V in designs that specify general‑purpose aluminum electrolytic capacitors with snap‑in mounting.
• High‑Voltage Power Assemblies — Suitable for equipment requiring 400 V rated capacitance with sustained ripple handling and 105°C endurance.
• Production‑Level Installations — Tray packing and snap‑in can format simplify board assembly and mechanical retention in volume manufacturing.

Unique Advantages

• Extended Endurance: 3,000 hours at 105°C under rated ripple conditions—supporting long operational life in elevated temperature environments.
• High Voltage Capacity: 400 V rating paired with 220 µF capacitance provides substantial energy storage for high‑voltage power rails.
• Robust Ripple Handling: Specified ripple currents at both low and high frequencies let designers size bulk and decoupling capacitance with confidence.
• Snap‑in Mechanical Retention: Radial snap‑in can (φ35×25L) enables secure through‑hole mounting for reliable mechanical and electrical connection.
• Regulatory Compliance: RoHS compliance supports integration into products targeting restricted‑substance requirements.
