LGN2W221MELB30

The LGN2W221MELB30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGN series, offering 220 µF capacitance at a 450 V rating in a compact radial can (φ30×30L). It is designed for general-purpose applications that require high-voltage operation, extended endurance, and robust ripple handling.

Key value propositions include a 450 V rated voltage, endurance of 3000 hours at 105°C, and high ripple current capability across both low and high frequency ranges—providing reliable smoothing and energy storage in demanding thermal and electrical environments.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable for high-voltage general-purpose designs.
• High-temperature Endurance: Rated for 3000 hours at 105°C, supporting long-term operation under elevated temperature and ripple stress.
• Ripple Current Performance: Handles 1.05 A at 120 Hz (low frequency) and 1.502 A at 100 kHz (high frequency), enabling effective ripple smoothing across a wide frequency range.
• Leakage and Dissipation: Low leakage current of 940 µA and a tangent of loss angle (tan δ) of 0.20 (measured at 20°C, 120 Hz), giving predictable loss characteristics for power designs.
• Form Factor & Mounting: Snap-in terminal radial can in a compact φ30×30L package (approx. 3 × 3 cm), simplifying installation in chassis or PCB assemblies where snap-in mounting is preferred.
• Operating Range & Polarity: Polarized capacitor with an operating temperature range of −25°C to 105°C, supporting a wide range of environmental conditions.
• Compliance & Packaging: RoHS compliant; supplied in tray packing and currently in mass production.

Typical Applications

• Industrial power supplies: 450 V rating and high ripple current capability make it suitable for smoothing and bulk energy storage in high-voltage power supply stages.
• Power conversion and inverters: Extended 3000-hour endurance at 105°C and robust high-frequency ripple handling support demanding converter environments.
• General-purpose electronic equipment: Compact snap-in package and RoHS compliance simplify integration into commercial and industrial assemblies requiring reliable DC link or filtering capacitors.

Unique Advantages

• High-voltage capability: 450 V rating provides the headroom needed for higher-voltage circuits without up-specifying components.
• Long-term thermal reliability: 3000 hours endurance at 105°C ensures sustained performance under prolonged thermal stress.
• Broad ripple performance: Strong ripple current ratings at both 120 Hz and 100 kHz reduce overheating risk and improve filtering effectiveness across frequency bands.
• Compact snap-in format: φ30×30L snap-in can offers a smaller footprint while enabling secure mechanical mounting for chassis and PCB installations.
• Predictable electrical characteristics: Specified tan δ (0.20 at 20°C, 120 Hz) and defined leakage current (940 µA) support more accurate loss and thermal calculations during design.
• RoHS compliant and production-ready: Meets RoHS directive requirements and is available in tray packing with mass production status for consistent supply.
