LGX2W151MELA30

The LGX2W151MELA30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX series designed for long life and compact mounting. It delivers 150 µF at 450 V in a smaller-sized radial can with snap‑in terminals, optimized for high-voltage power circuits.

Engineered for power-electronics use, this capacitor is suited for rectifier circuits in general inverters and switching power supplies, offering long-life assurance with 5000 hours of rated ripple-current endurance at 105°C and RoHS compliance.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance at 450 V for high-voltage filter and energy‑storage requirements.
• Long-life Endurance — Designed to withstand 5000 hours of rated ripple-current operation at 105°C, supporting prolonged thermal and electrical stress in power circuits.
• High Operating Temperature — Rated for operation from −25°C to +105°C to cover elevated ambient environments within specified limits.
• Ripple Current Ratings — 880 mA at 120 Hz and 1.258 A at 50 kHz, supporting common mains- and high-frequency ripple conditions in rectifier and switching stages.
• Snap‑In Radial Can — Snap‑in mounting type for secure PCB installation in compact assemblies; package described as radial, can - snap‑in.
• Leakage Current Specification — Leakage defined by the series formula I ≤ 3√CV (µA) after 5 minutes at 20°C, enabling predictable low-leakage behavior.
• Polarized Construction — Polarized electrolytic design for DC filter and smoothing applications.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions — Smaller‑sized body with physical dimensions L: 3 cm × D: 2.5 cm and a seated height up to 1.181 inch for space‑constrained designs.

Typical Applications

• Rectifier Circuits for Inverters — Provides bulk capacitance and ripple handling for rectifier stages in general inverter designs.
• Switching Power Supplies — Used for smoothing and energy storage where high voltage and long life at elevated temperature are required.
• General Purpose Power Electronics — Suitable for a variety of DC filter and energy‑storage roles in general purpose power circuitry.

Unique Advantages

• Long operational life: 5000 hours of rated ripple-current endurance at 105°C reduces replacement frequency and supports sustained high-temperature operation.
• High-voltage capability: 450 V rating enables use in higher-voltage rectifier and power-conversion topologies.
• Strong ripple performance: Explicit ripple current ratings at 120 Hz and 50 kHz provide designers with clear operating limits for both mains and high-frequency switching environments.
• Predictable leakage behavior: Leakage current defined by the industry-standard I ≤ 3√CV formula ensures predictable performance after initial voltage application.
• Space-conscious snap‑in package: Smaller-sized radial can with snap‑in terminals simplifies board layout in compact power modules.
• Regulatory compliance: RoHS conformity supports compliance requirements for lead‑restricted applications.
