LGX2W271MELC30

The LGX2W271MELC30 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for long-life operation at elevated temperatures. It delivers 270 µF at 450 V with polarized construction and is part of Nichicon’s LGX series targeted at general-purpose power applications.

Engineered for rectifier circuits in general inverters and for switching power supplies, this smaller-sized, long-life unit withstands 5000 hours of rated ripple current at 105°C and is RoHS compliant.

Key Features

• Electrical Capacity and Voltage — 270 µF rated capacitance at 450 V with ±20% tolerance, suitable for high-voltage filtering and energy storage in power circuits.
• High-Temperature Long Life — Designed to meet endurance requirements after 5000 hours of DC bias plus rated ripple current at 105°C, ensuring long-term performance in hot operating environments.
• Ripple Current Capability — Rated ripple current of 1.24 A at 120 Hz and 1.773 A at 50 kHz for effective smoothing of rectified and switching waveforms.
• Operating Temperature Range — Specified for −25°C to +105°C operation to cover a wide range of industrial and commercial environments.
• Snap-In Terminal, Radial Can Package — Snap-in mounting style for PCB installation, supplied in a smaller-sized radial can (approx. L: 3 × D: 3.5 cm).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverters (rectifier circuits) — Suitable for use in rectifier stages of general inverters where high-voltage filtering and long-term thermal endurance are required.
• Switching Power Supplies — Used for smoothing and bulk storage in high-voltage switching regulator and power-conversion topologies.
• General-Purpose Power Electronics — Applicable wherever a polarized, high-voltage electrolytic capacitor with extended high-temperature life is needed.

Unique Advantages

• Extended High-Temperature Endurance — 5000 hours at 105°C under rated conditions provides predictable life performance in demanding thermal environments.
• High Voltage Capability — 450 V rating addresses high-voltage DC link and rectifier requirements without series stacking.
• Documented Ripple Performance — Published ripple current ratings at both 120 Hz (1.24 A) and 50 kHz (1.773 A) allow designers to match the capacitor to expected operating ripple profiles.
• Compact Snap-In Construction — Smaller-sized radial can with snap-in terminals simplifies panel/PCB mounting for power assemblies requiring secure through-hole capacitor installation.
• RoHS Compliance — Conforms to current RoHS requirements for use in regulated markets.
