LGX2H121MELA35

The LGX2H121MELA35 is a Nichicon snap-in aluminum electrolytic capacitor designed for high-voltage power applications. It provides 120 µF capacitance at a 500 V rating in a compact radial, can-type snap-in package (φ25 × 35 mm).

Engineered for power conversion and rectifier circuits, this capacitor delivers long-life performance with a 5000-hour endurance rating at 105°C and is suitable for general-purpose industrial inverter and switching power supply use cases.

Key Features

• Capacitance & Voltage: 120 µF rated capacitance with a 500 V rated voltage, tolerance ±20% (120 Hz, 20°C).
• Snap‑in Package: Radial, can-type snap-in mounting for secure PCB attachment and ease of assembly in power modules.
• High-Temperature Long Life: Rated endurance of 5000 hours at 105°C when subjected to DC bias plus rated ripple current, supporting extended operation in elevated-temperature environments.
• Ripple Handling: Rated ripple current 930 mA at 120 Hz, 105°C and 1.33 A at 50 kHz, making it suitable for smoothing and filtering in power supplies and converters.
• Low Leakage: Specified leakage current of 0.73 mA (after rated voltage application conditions as defined in the datasheet).
• Operating Temperature Range: −25°C to +105°C for broad environmental compatibility within industrial ranges.
• Polarized Electrolytic: Polarized design for DC bus, filtering and energy-storage applications where polarity is maintained.
• Compliance: RoHS compliant, meeting applicable environmental directive requirements.

Typical Applications

• Switching Power Supplies: Bulk smoothing and ripple filtering in high-voltage switch-mode power supplies where 500 V rating and high ripple capability are required.
• Inverter Rectifier Circuits: DC-link and rectifier smoothing in general inverters, leveraging the 5000-hour life at 105°C for reliable operation under sustained ripple stress.
• Industrial Power Electronics: Energy storage and decoupling in industrial converters and power modules that require a compact, snap-in high-voltage capacitor.

Unique Advantages

• High-Voltage Capacity: 500 V rating enables use in higher-voltage DC-link and rectifier designs without series stacking of capacitors.
• Compact Snap‑In Form Factor: φ25 × 35 mm radial can with snap-in terminals reduces PCB footprint while providing robust mechanical mounting.
• Long Life at Elevated Temperature: 5000 hours rated life at 105°C under rated ripple conditions supports durability in thermally demanding applications.
• Designed for Ripple Stress: 930 mA at 120 Hz (105°C) and 1.33 A at 50 kHz ratings allow effective handling of high ripple currents common in power conversion.
• Controlled Leakage: Specified leakage current (0.73 mA) aids predictable performance during long-term operation and during voltage hold conditions.
• Regulatory Compliance: RoHS compliance ensures alignment with environmental requirements for electronic assemblies.
