LGX2W221MELB35

The LGX2W221MELB35 is a Nichicon LGX-series aluminum electrolytic capacitor in a snap-in terminal package, designed for board-level power conditioning. It provides 220 µF capacitance at a 450 V rating in a compact radial can with snap-in mounting.

Engineered for power electronics, this capacitor is suited for rectifier circuits in general inverters and switching power supplies where long-term endurance, elevated-temperature capability and stable ripple handling are required. It is RoHS compliant.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 450 V rated voltage, useful for medium-voltage smoothing and DC link applications.
• Long-life Endurance: Designed to withstand 5000 hours of rated ripple current at 105°C, providing predictable aging and performance over extended elevated-temperature operation.
• High Ripple Current Handling: Rated ripple currents of 1.17 A at 120 Hz and 1.673 A at 50 kHz support effective filtering of power-conversion noise.
• Temperature Range: Operates from −25°C to +105°C, allowing use in a range of industrial and commercial environments.
• Electrical Stability: For the 450 V rating, tan δ is specified up to 0.20 (measurement at 120 Hz, 20°C) and leakage current conforms to I ≤ 3√(C·V) µA after 5 minutes at 20°C, enabling predictable loss and leakage behavior.
• Package & Mounting: Radial, can-type snap-in package (snap-in terminal) with compact dimensions (L: 3.5 × D: 3 cm) and a maximum seated height of 1.378 inches for board-level power assemblies.
• Polarized with Standard Tolerance: Polarized capacitor with capacitance tolerance of −20% to +20%.
• Regulatory Compliance: Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter Rectifier Circuits: Used as DC-link and smoothing capacitors in rectifier stages of general inverters where 450 V rating and high ripple handling are required.
• Switching Power Supplies: Suitable for bulk filtering and energy storage in switching power supplies operating at elevated temperatures.
• Industrial Power Electronics: Applied in general-purpose power conditioning for industrial equipment requiring long-life capacitors rated for 105°C endurance.

Unique Advantages

• Extended High-Temperature Life: 5000-hour endurance at 105°C reduces maintenance and replacement frequency in high-temperature power systems.
• Medium-Voltage Capability: 450 V rating supports robust DC-link and rectifier designs without series stacking for many applications.
• Robust Ripple Performance: Specified ripple current at both low and high frequencies helps maintain filtering effectiveness across switching environments.
• Predictable Electrical Parameters: Clear specifications for tan δ and leakage current enable designers to model losses and reliability accurately.
• Compact Snap-In Form Factor: Radial snap-in construction and compact dimensions allow secure board mounting and efficient use of PCB area in power modules.
• RoHS Compliant: Meets current RoHS requirements for environmentally restricted substances.
