LGX2H151MELC25

The LGX2H151MELC25 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGX series. It provides 150 µF capacitance at a 500 V rated voltage in a compact φ35 × 25 mm can and is designed for general-purpose power applications.

Engineered for long-life operation, this part offers high ripple-current handling and 5000 hours endurance at 105°C, making it suitable for rectifier circuits, inverters and switching power supply designs that require robust, high-voltage bulk capacitance.

Key Features

• Electrical Performance — 150 µF nominal capacitance with ±20% tolerance and a 500 V rated voltage for high-voltage power applications.
• High Ripple Current Handling — Rated ripple current of 990 mA at 120 Hz and approximately 1.416 A at higher frequency operation, supporting demanding ripple conditions.
• Low Loss (tan δ) — Specified tan δ up to 0.20 (measured at 20°C, 120 Hz), indicating controlled dissipation factor for stable performance.
• Long-Life Endurance — Designed to meet endurance requirements after 5000 hours of DC bias plus rated ripple current at 105°C.
• Wide Operating Temperature — Rated for operation from −25°C to +105°C to cover common industrial temperature ranges.
• Low Leakage Current — Typical leakage current specified at 820 µA after rated voltage application.
• Package & Mounting — Radial, snap-in can package (φ35 × 25 mm) for secure board mounting; supplied in tray packing and offered in mass production status.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Inverter Rectifier Circuits — Bulk smoothing and energy storage in rectifier and inverter front-ends where 500 V ratings are required.
• Switching Power Supplies — DC bus and filtering applications that benefit from high ripple-current capability and 105°C long-life assurance.
• General Power Filtering — General-purpose power applications requiring reliable high-voltage capacitance and long-term endurance.

Unique Advantages

• 500 V Rated Voltage: Enables use in high-voltage power circuits without up-rating multiple lower-voltage components.
• Long 105°C Endurance: 5000 hours rated life at 105°C supports designs targeting extended operational lifetimes under elevated temperatures.
• Robust Ripple Handling: 990 mA at 120 Hz and ~1.416 A at higher frequency provide margin for heavy ripple and high-frequency switching environments.
• Compact Snap-In Form Factor: φ35 × 25 mm radial can with snap-in terminals simplifies secure mounting and board-level retention for power assemblies.
• Controlled Loss and Leakage: tan δ ≤ 0.20 (20°C, 120 Hz) and leakage current around 820 µA contribute to predictable thermal and leakage behavior in designs.
• Production-Ready Packaging: Tray packing and mass production status support volume assembly and procurement planning.
