LGX2G271MELB30

The LGX2G271MELB30 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for long-life operation at elevated temperatures. It offers a 270 µF capacitance at a 400 V rating with a compact φ30 × 30 mm profile and tray packaging for volume production.

Engineered for power-electronics applications, this part is suited for rectifier circuits in general inverters and switching power supplies and other general-purpose power filtering roles where high ripple tolerance and extended endurance at 105°C are required.

Key Features

• Core Type & Mounting — Aluminum electrolytic capacitor with snap-in terminals in a radial can package for secure PCB installation.
• Capacitance & Voltage — 270 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Temperature Range & Endurance — Operates from −25℃ to +105℃ with a long-life assurance of 5000 hours at 105℃ under rated ripple conditions.
• High Ripple Capability — Rated ripple current of 1270 mA at 120 Hz (low frequency) and 1816.1 mA at 50 kHz (high frequency) to support demanding power circuits.
• Low Dissipation Factor — tan δ specified at 0.15 (max.) for rated voltages 200–400 V (measured at 120 Hz, 20℃), helping limit AC loss.
• Leakage Current — Low leakage current specified at 980 µA after rated voltage application.
• Compact Package & Packing — Smaller-sized φ30 × 30 mm can (3 × 3 cm) and supplied in tray packing for streamlined assembly and production.
• RoHS Compliance — Conforms to RoHS directive requirements.

Typical Applications

• Inverter Rectifier Circuits — Used as bulk smoothing and energy storage in rectifier stages of general inverters where 400 V DC rails are common.
• Switching Power Supplies — Provides filtering and ripple management on high-voltage DC buses in switching power supplies.
• General-Purpose Power Filtering — Suitable for industrial and commercial power-electronics designs requiring long life at elevated temperature and stable capacitance.

Unique Advantages

• Long-life endurance: Rated for 5000 hours at 105℃ with rated ripple applied, helping maintain capacitance, tan δ, and leakage stability over extended operation.
• High-voltage capability: 400 V rating supports high-voltage DC bus applications without requiring larger form factors.
• Robust ripple handling: High ripple current ratings at both 120 Hz (1270 mA) and 50 kHz (1816.1 mA) reduce heating and improve reliability in high-stress power circuits.
• Controlled dielectric loss: tan δ ≤ 0.15 (200–400 V range, 120 Hz, 20℃) to limit AC losses and thermal rise under ripple conditions.
• Compact snap-in form factor: φ30 × 30 mm smaller-sized can with snap-in terminals simplifies mechanical retention and PCB assembly for volume builds.
• Regulatory compliance & production readiness: RoHS compliant and supplied in tray packing for efficient integration into production lines.
