LGU2G221MELZ

The LGU2G221MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, designed for high‑voltage, general‑purpose power applications. With a 220 µF capacitance at a 400 V rating and a compact φ22 × 50 mm can, it delivers high ripple handling and long endurance for demanding power circuits.

Targeted at power supply and industrial power-conversion designs, this component balances high voltage capability, low leakage, and a 105°C endurance profile to support stable filtering and smoothing under sustained load.

Key Features

• Capacitance & Voltage — 220 µF capacitance rated at 400 V for high-voltage filtering and energy storage.
• Snap‑in Mechanical Package — Radial, snap‑in can (φ22 × 50 mm) for secure board mounting and high-current PCB installations.
• High Ripple Current Capability — Low‑frequency ripple current 1.1 A (120 Hz) and high‑frequency ripple current 1.573 A (50 kHz) to handle dynamic load ripple across a broad frequency range.
• Thermal and Endurance Rating — Rated for operation from −25°C to 105°C with endurance of 3000 hours at 105°C under rated ripple/current conditions.
• Low Loss & Leakage — Tangent of loss angle (tan δ) 0.15 (measured at 20°C, 120 Hz) and leakage current specified at 880 µA, supporting efficient energy transfer and low standby losses.
• Tolerance & Polarization — Capacitance tolerance −20% to +20%; polarized electrolytic design for conventional DC power applications.
• Compliance & Availability — RoHS compliant and available in tray packing for production-scale assemblies; product status: Mass Production.

Typical Applications

• Power Supply Filtering — Used for bulk smoothing and ripple suppression in high‑voltage DC power supplies and upstream filter stages.
• Industrial Power Conversion — Suited to converters and inverters where 400 V rated capacitance and sustained 105°C endurance are required.
• Energy Storage & Backup — Provides short‑term energy buffering and voltage stabilization in backup power and UPS system electronics.
• High‑Frequency Decoupling — With specified ripple current at frequencies up to 50 kHz, ideal for decoupling and smoothing in switching power circuits.

Unique Advantages

• High Voltage Handling: 400 V rating enables use in high‑voltage DC systems without parallel part arrangements.
• Robust Ripple Performance: Defined ripple currents at 120 Hz and 50 kHz ensure predictable thermal and electrical behavior under real load conditions.
• Extended High‑Temperature Endurance: 3000 hours at 105°C under rated ripple current supports long mean time between replacements in harsh environments.
• Compact Snap‑In Form Factor: φ22 × 50 mm snap‑in can provides a space-efficient solution for high‑current board layouts and secure mounting.
• Low Loss & Leakage: tan δ of 0.15 and leakage current of 880 µA contribute to efficient operation and reduced standby losses.
• Production‑Ready Packaging: Tray packing and Mass Production status facilitate BOM sourcing and medium‑to‑high volume assembly workflows.
