LGU2W151MELZ

The LGU2W151MELZ is a snap-in aluminum electrolytic capacitor from Nichicon's LGU series, providing 150 µF capacitance at a 450 V rating in a compact radial can. Designed for general-purpose high-voltage applications, it combines high ripple-current capability with extended endurance for robust power-conditioning duty.

Key value comes from its 105°C rated operation with 3000 hours endurance, industry-standard snap-in mounting, and RoHS compliance—making it suitable for production designs that require dependable high-voltage bulk capacitance and long service life.

Key Features

• Electrical Rating — 150 µF capacitance at a 450 V rated voltage with ±20% tolerance (120 Hz, 20°C), providing stable bulk energy storage for high-voltage circuits.
• Low Dissipation — tan δ of 0.2 (max) measured at 20°C and 120 Hz for the 450 V rating, indicating controlled losses in AC and ripple conditions.
• High Ripple Current Capability — Rated ripple current of 880 mA at 120 Hz and 1.258 A at 50 kHz, supporting both low- and high-frequency ripple in power supply and converter applications.
• Leakage Current — Specified leakage current of 770 µA, suitable for designs where controlled leakage is needed.
• Thermal Endurance — Rated for operation from −25°C to +105°C with a guaranteed 3000 hours life at 105°C under rated ripple conditions.
• Mechanical Package — Snap-in terminal, radial can package (φ22 × 45L; L: 4.5 × D: 2.2 cm), supplied in tray packing for production assembly.
• Compliance — RoHS compliant, supporting environmental requirements for modern electronic assemblies.

Typical Applications

• High-voltage power supplies — Bulk smoothing and energy storage in industrial and commercial power supplies where 450 V rating and 150 µF capacitance are required.
• Power conversion and inverters — DC-link and filtering duties in converter circuits benefiting from high ripple-current capability and 105°C endurance.
• Uninterruptible power systems and UPS modules — Energy storage and ripple suppression in systems that demand long-term reliability at elevated temperatures.

Unique Advantages

• 450 V rated voltage — Enables use in higher-voltage DC bus and power-supply designs without derating.
• High ripple tolerance across frequencies — Specified ripple currents at 120 Hz and 50 kHz accommodate both mains-frequency and switching-frequency ripple profiles.
• Proven thermal endurance — 3000 hours at 105°C under rated ripple current provides predictable life performance in elevated-temperature environments.
• Compact, production-ready package — φ22 × 45L snap-in can in tray packing simplifies assembly for mass-production runs.
• Controlled losses and leakage — tan δ = 0.2 and 770 µA leakage current support efficient operation and predictable standby characteristics.
• RoHS compliant — Meets environmental substance restrictions for regulated markets.
