LGU1V223MELC

The LGU1V223MELC is a Nichicon LGU series aluminum electrolytic capacitor in a snap-in terminal configuration, offering 22,000 µF capacitance at a 35 V rating. It is a general-purpose, radial can capacitor designed for applications that require large bulk capacitance with sustained ripple handling.

Key value comes from its high ripple current capability, extended endurance at elevated temperature, and a compact φ35 × 50 mm can size with snap-in mounting—making it suitable for industrial and power electronics designs that demand reliable energy buffering and smoothing.

Key Features

• Capacitance & Voltage  22,000 µF (22 mF) rated at 35 V with ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current Handling  Low-frequency ripple current 4.92 A at 120 Hz and high-frequency ripple current 5.658 A at 50 kHz, enabling effective filtering across a wide frequency range.
• Endurance at Elevated Temperature  Designed to withstand 3,000 hours of rated ripple current at 105°C when used under the specified conditions.
• Operating Temperature Range  Rated for −40°C to +105°C operation, supporting deployment in a wide range of thermal environments.
• Loss and Leakage Characteristics  Tangent of loss angle (tan δ) measured at 20°C, 120 Hz (max. tan δ for 35 V = 0.35); leakage current specified at 2,630 µA.
• Package & Mounting  Radial, snap-in can (φ35 × 50L) for secure PCB mounting and reliable mechanical retention; supplied in tray packing for production handling.
• Regulatory  RoHS compliant.

Typical Applications

• Power Supplies — Smoothing & Bulk Storage  Provides bulk capacitance and ripple current capability for DC power supply smoothing and energy storage.
• Power Converters & Inverters  Used for energy buffering and filtering in industrial converters where sustained ripple handling and elevated-temperature endurance are needed.
• UPS & Backup Systems  Supports hold-up and filtering roles in uninterruptible power supplies and backup power modules.
• Industrial Control Equipment  Suitable for controllers and power busses in industrial electronics requiring high capacitance and robust mounting.

Unique Advantages

• Substantial energy storage in a single device: 22,000 µF at 35 V reduces BOM and layout complexity compared to multiple smaller capacitors.
• Sustained high-temperature reliability: 3,000-hour endurance at 105°C under rated ripple current supports long-term operation in hot environments.
• Broad ripple performance: Specified ripple currents at both 120 Hz and 50 kHz allow effective filtering across low and high frequency domains.
• Robust snap-in mounting: Radial snap-in terminals provide mechanical stability and straightforward PCB assembly.
• Production-ready packaging and compliance: Tray packing and RoHS compliance streamline handling and regulatory requirements for manufacturing.
