LGW2D102MELA45

The LGW2D102MELA45 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications requiring high ripple handling and thermal robustness. Built for continuous operation up to 105°C, it delivers a 1 mF capacitance at a 200 V rating in a radial, can-style snap-in package.

This part targets power supply filtering, bulk energy storage and decoupling duties in industrial and commercial systems where high ripple current endurance and long operational life at elevated temperatures are required.

Key Features

• High Ripple Current — Rated ripple current of 3.45 A at 120 Hz and 5.175 A at 50 kHz, enabling effective smoothing and filtering in high-stress power circuits.
• 105°C Endurance — Designed to withstand 3000 hours application of rated ripple current at 105°C; after endurance test, capacitance change is within ±20%, tan δ remains ≤200% of initial, and leakage current stays at or below initial specified value.
• Rated Voltage and Capacitance — 200 V rated voltage with 1 mF capacitance and ±20% tolerance for predictable energy storage and decoupling behavior.
• Wide Operating Temperature — Operates from −40°C to +105°C to support a broad range of environmental conditions.
• Snap-in Radial Can Package — Snap-in mounting simplifies high-current PCB assembly and mechanical retention in power modules and supply boards.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory-compliant designs.
• Leakage Current Specification — Leakage current meets the series criterion I ≤ 3√CV (μA) after 5 minutes at 20°C, providing a verifiable electrical characteristic for design verification.

Typical Applications

• Power Supplies — Bulk smoothing and output filtering where sustained ripple current and thermal endurance at 105°C are required.
• Industrial Power Modules — Energy storage and decoupling in motor drives and industrial converters subject to continuous high ripple stress.
• UPS and Backup Systems — Bulk capacitance for energy buffering and ride-through where reliability over long elevated-temperature operation matters.

Unique Advantages

• Long High-Temperature Life: 3000-hour rated endurance at 105°C under rated ripple current preserves capacitance and limits tan δ growth, reducing maintenance and replacement frequency.
• High Ripple Handling: Specified ripple current values at multiple frequencies enable confident use in high-stress filtering and switching applications.
• Robust Temperature Range: −40°C to +105°C operation supports a wide range of deployment environments without derating outside of specified limits.
• Practical Snap-in Packaging: Radial snap-in can simplifies installation in PCB power layouts and supports secure mechanical mounting under high-current conditions.
• Regulatory Compliance: RoHS conformity helps streamline regulatory acceptance in commercial and industrial product lines.
