LGU1E223MELC

The LGU1E223MELC is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, delivering 22,000 µF capacitance at a 25 V rating. Engineered for general-purpose power applications, it combines high bulk capacitance with robust ripple-current capability and long-term endurance at elevated temperatures.

This snap-in, radial can package is optimized for designs that require high capacitance density, reliable high-temperature performance, and straightforward board retention and assembly.

Key Features

• Capacitance & Voltage  22,000 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple-Current Capability  Low-frequency ripple current of 3.96 A (120 Hz) and high-frequency ripple current of 4.554 A (50 kHz) to support demanding AC components on DC rails.
• Long Endurance at Elevated Temperature  Rated for 3,000 hours at 105°C under rated ripple-current conditions, with capacitance change and leakage current maintained within specified limits after endurance testing.
• Wide Operating Temperature Range  Operates from −40°C to +105°C to accommodate a broad range of thermal environments.
• Robust Packaging & Mounting  Snap-in radial can (φ35 × 35 mm) for secure PCB retention; supplied in tray packing for consistent handling in production.
• Leakage Current  Specified leakage current of 2,220 µA (after 5 minutes at rated voltage, 20°C) to help quantify self-discharge behavior in designs.
• Regulatory Compliance  RoHS compliant, aligning with modern environmental requirements.

Typical Applications

• General-purpose power systems  Bulk energy storage and smoothing where 22,000 µF at 25 V and elevated temperature endurance are required.
• Power-supply filtering  Filtering and decoupling on DC rails that demand substantial ripple-current handling and stable capacitance over time and temperature.
• Industrial and commercial equipment  Designs that require long life at 105°C and reliable snap-in mounting for secure mechanical and electrical performance.

Unique Advantages

• High bulk capacitance in a compact can  22,000 µF in a φ35 × 35 mm package provides significant energy storage without large board area penalties.
• Measured ripple performance  Specified ripple currents at both 120 Hz and 50 kHz let engineers size capacitors with frequency-specific data for accurate thermal and lifetime estimates.
• Designed for high-temperature endurance  3,000 hours at 105°C under rated ripple current demonstrates sustained performance in hot operating environments.
• Snap-in mounting for production reliability  Radial snap-in terminals ensure positive board retention and simplify assembly compared with adhesive-only solutions.
• Quantified leakage behavior  Leakage current specification (2,220 µA) allows predictable charge loss and design margin calculations.
• RoHS compliant and production-ready  Meets RoHS requirements and is available in tray packing for volume manufacturing.
