LGU2W121MELA

The LGU2W121MELA is a snap-in terminal type aluminum electrolytic capacitor designed for general-purpose power applications requiring high voltage handling and robust ripple endurance. Built to the LGU series specification, it delivers 120 µF capacitance at a 450 V rating with a compact φ25 × 30 mm can and snap-in mounting for secure mechanical retention.

This component targets equipment where sustained ripple performance and long-term reliability at elevated temperature are required, offering a combination of high-voltage capability, low leakage, and extended 105°C endurance suitable for demanding industrial and power-electronics environments.

Key Features

• Rated Voltage and Capacitance: 450 V nominal rating with 120 µF nominal capacitance and ±20% tolerance at 120 Hz, 20°C, supporting high-voltage energy storage and filtering.
• Snap-In Mounting: Radial can with snap-in terminals for secure board retention and simplified assembly in power modules and larger PCBs.
• Ripple Current Performance: 800 mA at 120 Hz (low frequency) and 1.144 A at 50 kHz (high frequency) to handle substantial AC ripple in power conversion and filtering applications.
• Low Leakage and Loss: 690 µA specified leakage current and tan δ (DF) of 0.20 measured at 20°C and 120 Hz for controlled loss characteristics.
• High-Temperature Endurance: Rated for 3,000 hours at 105°C with compliance to the LGU series endurance criteria, maintaining capacitance, tan δ, and leakage within specified limits after endurance testing.
• Operating Temperature Range: Specified for –25°C to +105°C for the 315–450 V rating, enabling operation across a broad thermal envelope.
• Compliance and Availability: RoHS compliant, tray packed, and in mass production for consistent supply and regulatory conformity.

Typical Applications

• General-purpose power supplies: Energy storage and smoothing where a 450 V rated capacitor with high ripple capability is required.
• Power conversion modules: Filtering and decoupling in high-voltage inverters and converters that demand durable ripple endurance at elevated temperature.
• Industrial power equipment: Bulk capacitance and ripple handling in industrial power systems benefiting from snap-in mounting and long 105°C endurance.

Unique Advantages

• High-voltage capability: 450 V rating supports designs that require elevated DC link or HV bus capacitance without parallel parts.
• Long 105°C endurance: 3,000-hour rated life at 105°C provides predictable aging and reliability for long-term deployments.
• Robust ripple handling: Dual-frequency ripple specifications (800 mA @120 Hz and 1.144 A @50 kHz) address both low- and high-frequency ripple stress.
• Low leakage and controlled dissipation: 690 µA leakage and a tan δ of 0.20 at test conditions reduce standby losses and improve efficiency margins.
• Secure snap-in mounting: Radial snap-in terminals simplify mechanical assembly and ensure stable placement in power assemblies.
• Regulatory readiness: RoHS compliance supports environmental requirements without additional component qualification.
