LGX2E331MELZ30

The LGX2E331MELZ30 is an aluminum electrolytic capacitor in a snap‑in radial can package designed for long life operation at elevated temperatures. It provides 330 µF capacitance at a 250 V rating, polarized construction, and compact dimensions (L: 3 × D: 2.2 cm) for power electronics applications.

Engineered for demanding power circuits, this part is suited to rectifier stages in general inverters and switching power supplies, offering 5000 hours endurance under rated ripple current at 105°C. The product is RoHS compliant.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, providing bulk energy storage and smoothing in power stages.
• High‑temperature Long Life: Rated for operation from −25°C to +105°C and guaranteed for 5000 hours when subjected to DC bias plus rated ripple current at 105°C.
• Snap‑in Radial Can Package: Snap‑in terminal mounting for secure PCB retention in power assemblies and compact footprint of approximately 3 × 2.2 cm.
• Ripple Current Capability: Supports ripple currents of 1.2 A at 120 Hz and 1.8 A at 50 kHz, suitable for typical rectifier and switching environments.
• Reliability Characteristics: Endurance requirements specify capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value after the 5000 h endurance test.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863), meeting environmental regulatory requirements.
• Leakage Current Specification: Leakage current follows the series formula I ≤ 3√CV (μA) after 5 minutes at 20°C, allowing predictable leakage behavior for design calculations.

Typical Applications

• Inverter Rectifier Stages: Bulk filtering and smoothing in rectifier circuits for general inverters where sustained ripple handling and high‑temperature endurance are required.
• Switching Power Supplies: Output and bulk capacitors in SMPS designs that demand stable capacitance and specified ripple current at elevated temperatures.
• Industrial Power Electronics: Energy storage and smoothing in industrial power assemblies that operate up to 105°C and require long life performance.

Unique Advantages

• Long Endurance at Elevated Temperature: 5000 hours at 105°C under rated ripple current provides predictable lifetime behavior for high‑temperature applications.
• Designed for Power Rectification: Specification and endurance tailored to rectifier circuits in inverters and switching supplies, simplifying component selection for these roles.
• Compact Snap‑in Package: Snap‑in terminals and a small can footprint enable reliable PCB mounting while conserving board space in densely packed power designs.
• Clear Performance Limits: Defined ripple current ratings at both low and high frequencies (120 Hz and 50 kHz) let designers size capacitors against application‑specific ripple conditions.
• Measurable Reliability Metrics: Endurance and shelf‑life limits for capacitance, tan δ, and leakage current provide quantifiable expectations for life and storage handling.
• Regulatory Compliance: RoHS conformance supports use in products that require restricted‑substance compliance.
