LGU2W221MELA

The LGU2W221MELA is a Nichicon LGU series snap-in aluminum electrolytic capacitor specified at 220 µF and 450 V. It is a snap-in terminal, radial can type designed for general-purpose applications that require high-voltage capacitance with controlled loss and defined ripple-handling capability.

Designed to operate across a wide temperature range (−25 °C to 105 °C) and to withstand 3,000 hours of rated ripple current at 105 °C per the LGU series specification, this part supports continuous high-temperature operation and long-term reliability in demanding environments.

Key Features

• Capacitance & Tolerance — 220 µF with a tolerance of −20% to +20% at 20 °C, 120 Hz.
• High Rated Voltage — 450 V DC rating suitable for high-voltage DC circuits.
• Low Loss — tan δ (DF) of 0.2 measured at 20 °C, 120 Hz for controlled dissipation.
• Ripple Current Capability — Low-frequency ripple current 1.12 A at 120 Hz and high-frequency ripple current 1.602 A at 50 kHz, enabling effective smoothing of AC-derived and switching waveforms.
• Leakage Current — Specified leakage current of 940 µA (measured after rated voltage application at 20 °C).
• Thermal Endurance — Rated for 3,000 hours of operation at 105 °C with DC bias plus rated ripple current per LGU series endurance criteria.
• Operating Temperature — −25 °C to 105 °C.
• Package & Mounting — Snap-in radial can (φ25 × 45 mm), tray packing for assembly handling.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• General-purpose power filtering — 220 µF at 450 V provides bulk capacitance for smoothing and energy storage in high-voltage DC circuits where general-purpose capacitors are specified.
• High-voltage DC link support — High rated voltage and specified ripple current values make it suitable for DC link and intermediate circuit filtering under continuous load and elevated temperature conditions.
• Industrial electronics — Long endurance at 105 °C supports use in industrial equipment requiring stable capacitance and leakage performance over extended operating periods.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage circuits without series stacking.
• Defined ripple endurance: Rated ripple currents (1.12 A @120 Hz; 1.602 A @50 kHz) and 3,000 h endurance at 105 °C provide predictable performance under continuous ripple stress.
• Stable dissipation characteristics: tan δ of 0.2 at 120 Hz helps control power loss and temperature rise in the capacitor.
• Compact snap-in package: φ25 × 45 mm radial can with snap-in terminals simplifies PCB mounting for vertical power modules and assemblies.
• Environmentally compliant: RoHS compliance supports regulatory requirements for electronic assemblies.
• Production-ready supply: Listed as mass production with tray packing for pick-and-place or manual assembly.
