LGX2G121MELZ30

The LGX2G121MELZ30 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power electronics. It delivers 120 µF capacitance at a 400 V rating in a compact φ22 × 30 mm can, optimized for rectifier stages and switching power supplies.

Engineered for long-life operation, this Nichicon LGX series part provides extended endurance under rated ripple and elevated temperature, making it suitable for inverter and industrial power applications that require sustained performance and reliability.

Key Features

• Capacitance & Voltage – 120 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Long-life Endurance – 5000 hours rated life at 105°C with DC bias plus rated ripple current applied, meeting LGX series long-life assurance criteria.
• Ripple Current Handling – 750 mA low-frequency ripple current at 120 Hz and 1.073 A high-frequency ripple current at 50 kHz to support rectifier and smoothing duties in power supplies.
• Low Loss & Leakage – Maximum tan δ of 0.15 (at 20°C, 120 Hz) and a specified leakage current of 650 µA for controlled dissipation and stable performance.
• Wide Operating Temperature – Rated for operation from −25°C to +105°C to cover a broad range of industrial environments.
• Robust Package & Mounting – Snap-in radial can (φ22 × 30 mm) for secure chassis or power-module mounting; supplied in tray packing and offered in mass production status.
• RoHS Compliant – Manufactured in compliance with RoHS requirements.

Typical Applications

• Inverters and Motor Drives – Bulk smoothing and DC link duties where 400 V rating and elevated ripple handling are required.
• Switching Power Supplies – Input/output filtering and energy storage for rectifier and converter stages in industrial power supplies.
• Rectifier Circuits – Smoothing and ripple reduction after rectification in general-purpose power conversion.
• Industrial Power Modules – Long-life capacitor for applications requiring sustained operation at up to 105°C.

Unique Advantages

• High-voltage capability: 400 V rating supports high-voltage DC link and rectifier applications without additional series components.
• Designed for sustained ripple: Rated ripple currents at both low and high frequencies reduce the need for overspecifying parallel components.
• Extended high-temperature life: 5000-hour endurance at 105°C provides predictable aging and long-term stability in warmer environments.
• Compact, secure mounting: φ22 × 30 mm snap-in can balances board space and mechanical retention for power assemblies.
• Measured electrical stability: Low tan δ and specified leakage make performance easier to predict in power designs.
• Production-ready supply: Tray packing and mass production status support volume procurement and assembly workflows.
