LGX2G221MELA35

The LGX2G221MELA35 is a Nichicon LGX series aluminum electrolytic capacitor in a radial, snap‑in can package. It provides 220 µF nominal capacitance at a 400 V rating and is polarized for DC applications.

Engineered for power-electronics use, this part is suited for rectifier circuits in general inverters and switching power supplies. It delivers long-life performance, rated to withstand rated ripple current for 5000 hours at 105°C, and is RoHS compliant.

Key Features

• Long-life reliability — Endurance specified to meet performance after 5000 hours of DC bias plus rated ripple current at 105°C.
• Nominal electrical characteristics — 220 µF capacitance with ±20% tolerance (measured at 120 Hz, 20°C) and polarized construction for DC filtering and smoothing.
• High working voltage — Rated for 400 V operation suitable for higher-voltage power rails and rectifier stages.
• Ripple current capability — Rated ripple current: 1.12 A at 120 Hz and 1.602 A at 50 kHz, supporting typical inverter and SMPS ripple environments.
• Temperature performance — Operating temperature range from −25°C to +105°C; impedance stability at low temperature with Z(−25°C)/Z(+20°C) up to 8 for the 400–500 V category.
• Leakage and dissipation — Leakage current specified as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ (loss tangent) max 0.15 for the 200–400 V range (measured at 120 Hz, 20°C).
• Package and mounting — Radial snap‑in can for secure board mounting and compact installation; nominal dimensions L: 3.5 × D: 2.5 cm.
• Environmental compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter rectifier circuits — Used for smoothing and bulk energy storage in rectifier stages of general inverters.
• Switching power supplies — Functions as input/output filtering and energy reservoir to support stable DC rails in SMPS designs.
• Industrial power electronics — Employed where high-voltage DC filtering and long operating life at elevated temperature are required.

Unique Advantages

• Designed for long-term high-temperature operation — Endurance rating of 5000 hours at 105°C under rated ripple current reduces frequency of replacements in high-stress power applications.
• High-voltage capability — 400 V rating supports higher-voltage DC bus designs without series stacking.
• Measured ripple specifications — Explicit ripple current ratings at both 120 Hz and 50 kHz allow designers to size capacitors for real-world low- and high-frequency ripple profiles.
• Predictable electrical loss and leakage — Specified tan δ and leakage-current formula (I ≤ 3√CV) enable accurate thermal and leakage budgeting during design.
• Compact snap-in format — Radial snap‑in package with modest footprint (3.5 × 2.5 cm) simplifies board layout for power assemblies.
• RoHS compliance — Meets regulatory requirements for lead-free applications.
