The LGX2H331MELC45 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX series designed for long‑life power applications. It provides 330 µF capacitance at a 500 V rating in a radial, snap‑in can package.

Engineered for rectifier stages and general power electronics, the part delivers a combination of high voltage, rated ripple capability, and a long endurance specification (5000 hours at 105 °C), making it suitable for inverters and switching power supplies and other general‑purpose power applications.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 500 V for high‑voltage smoothing and energy storage.
• Long Life Assurance — Endurance specified as 5000 hours with rated ripple at 105 °C, supporting extended operation under elevated temperature and ripple conditions.
• Package & Mounting — Radial, snap‑in can package for secure chassis/PCB mounting; snap‑in terminal type for high mechanical stability in power assemblies.
• Operating Range — Rated for operation from −25 °C to +105 °C, suitable for a wide range of industrial environments.
• Ripple Current Performance — Rated ripple current of 1.6 A at 120 Hz and 2.288 A at 50 kHz, supporting common rectifier and switching conditions.
• Electrical Characteristics — Polarized electrolytic capacitor with capacitance tolerance of −20% to +20% and leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20 °C (series specification).
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical size L: 4.5 × D: 3.5 cm with a seated height specification, enabling dense power module layouts.

Typical Applications

• General Inverters — Used in rectifier and DC‑link stages for inverter systems requiring 500 V smoothing and long‑life operation.
• Switching Power Supplies — Bulk filtering and energy storage in high‑voltage switching supplies where ripple endurance at elevated temperature is required.
• General‑Purpose Power Electronics — High‑voltage applications in industrial power modules and assemblies that need reliable polarized capacitance and robust mounting.

Unique Advantages

• Long endurance at elevated temperature: 5000‑hour rated life at 105 °C with rated ripple current, reducing maintenance and replacement frequency in hot operating environments.
• High voltage capability: 500 V rating provides headroom for high‑voltage DC applications and rectifier circuits without series stacking.
• Designed for power‑handling: Specified ripple currents at both low and high frequency (1.6 A at 120 Hz; 2.288 A at 50 kHz) align with common rectifier and switching conditions.
• Robust snap‑in mounting: Radial snap‑in can provides a mechanically secure mounting option for power modules and chassis assemblies.
• Clear electrical limits: Polarized design with ±20% capacitance tolerance and a defined leakage current formula (I ≤ 3√CV) helps designers predict in‑circuit behavior.
• RoHS compliance: Meets RoHS directive requirements, supporting restricted‑substance compliance for commercial and industrial projects.
