LGX2W221MELC25

The LGX2W221MELC25 is a snap‑in terminal aluminum electrolytic capacitor designed for high‑voltage power applications. It delivers 220 µF capacitance at 450 V in a compact φ35 × 25 mm can and is optimized for long life and high ripple capability.

Engineered for power conversion and rectifier circuits—including inverters and switching power supplies—this capacitor combines high ripple current handling, low leakage, and 105°C long‑life assurance to support robust, high‑temperature designs. It is available in tray packing for mass production environments.

Key Features

• Electrolytic Core & Mounting Aluminum electrolytic construction with snap‑in radial can for secure board mounting and high current handling in compact orientations.
• Rated Capacitance & Voltage 220 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 450 V to support high‑voltage DC bus and rectifier duties.
• High‑Temperature Long Life Designed for operation from -25°C to +105°C with a 5000‑hour endurance rating at 105°C, supporting prolonged operation in elevated ambient conditions.
• Ripple Current Performance 1.100 A low‑frequency ripple current at 120 Hz and 1.573 A high‑frequency ripple current at 50 kHz to handle bulk filtering and smoothing under heavy ripple loads.
• Loss and Leakage Characteristics Tan δ (DF) of 0.2 max at 20°C, 120 Hz and measured leakage current of 940 µA—helpful for maintaining efficiency and minimizing self‑heating in DC link applications.
• Compact Package & Production Ready Smaller‑sized φ35 × 25 mm body (L: 2.5 cm × D: 3.5 cm), snap‑in terminals, and tray packing suitable for automated assembly and volume production flows.
• RoHS Compliant Meets RoHS requirements for environmental compliance.

Typical Applications

• Power Conversion Bulk filtering and DC link duties in inverters and switching power supplies where high voltage and sustained ripple handling are required.
• Rectifier Circuits Smoothing and energy storage on high‑voltage rectifier outputs for industrial power modules and distributed power systems.
• General Purpose Industrial Electronics Use in high‑temperature industrial control and power conditioning equipment that demands long life and stable capacitance at elevated temperatures.

Unique Advantages

• Long‑Life Endurance: 5000 hours at 105°C provides predictable aging characteristics for designs intended for extended service life in hot environments.
• High Ripple Capability: Specified low‑ and high‑frequency ripple currents (1.100 A @120 Hz; 1.573 A @50 kHz) reduce the need for parallel components and simplify BOM for power stages.
• Compact High‑Voltage Form Factor: 220 µF at 450 V in a φ35 × 25 mm can saves board space compared with larger high‑voltage solutions, enabling denser power assemblies.
• Low Leakage and Controlled Losses: 940 µA leakage and tan δ specified behavior support reduced self‑heating and improved efficiency in DC bus applications.
• Production‑Friendly Packaging: Tray packing and snap‑in terminals facilitate automated insertion and reliable mechanical mounting in volume builds.
• Regulatory Compliance: RoHS compliance supports environmental requirements for commercial and industrial products.
