LGU1C223MELB

The LGU1C223MELB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series, designed for general-purpose power applications. It delivers high bulk capacitance (22,000 µF) at a rated voltage of 16 V in a radial snap-in can for board-mounted use.

Engineered for robust thermal endurance, this part is specified for operation from –40°C to +105°C and is rated for 3,000 hours of ripple-current endurance at 105°C, making it suitable for demanding DC filtering and bulk energy-storage roles where long-term stability and high ripple handling are needed.

Key Features

• High Capacitance: 22,000 µF (22 mF) provides substantial bulk energy storage for smoothing and decoupling applications.
• Rated Voltage: 16 V working voltage suitable for low-voltage DC power rails.
• Ripple Current Performance: Low-frequency ripple current 3.39 A (120 Hz) and high-frequency ripple current 3.898 A (50 kHz) for handling significant AC stress on DC rails.
• Endurance at Elevated Temperature: Specified for 3,000 hours at 105°C under rated ripple conditions, with post-test limits on capacitance change, dissipation factor, and leakage current defined by the LGU series endurance criteria.
• Wide Operating Temperature Range: –40°C to +105°C to cover a broad range of ambient conditions.
• Electrical Characteristics: Capacitance tolerance ±20%; tan δ (DF) 0.5 measured at 20°C, 120 Hz; leakage current 1,770 µA (after specified voltage application).
• Package and Mounting: Radial snap-in can, physical size φ30 × 35L (30 mm diameter × 35 mm length), tray packing for handling and assembly.
• Regulatory: RoHS compliant.

Typical Applications

• General-Purpose Power Supplies — Bulk smoothing and energy buffering on 16 V rails where 22,000 µF capacitance and multi-amp ripple handling are required.
• Industrial Power Modules — DC-link and filter applications that need sustained ripple endurance at elevated temperatures (3,000 h at 105°C).
• Energy Storage & Decoupling — Local energy reservoir for systems requiring large capacitance in a compact snap-in radial can.

Unique Advantages

• Large Bulk Capacity: 22,000 µF reduces the number of parallel components needed for equivalent storage, simplifying BOM and board layout.
• Strong Ripple Handling: Rated ripple currents of 3.39 A (120 Hz) and 3.898 A (50 kHz) enable reliable performance under AC stress typical in power conversion circuits.
• Thermal Endurance: 3,000-hour endurance at 105°C provides predictable long-term behavior in high-temperature environments.
• Robust Mounting: Snap-in terminal radial can simplifies secure board installation for high-current and high-vibration applications.
• Clear Electrical Limits: Specified tan δ, leakage current, and capacitance tolerance make it straightforward to design within measured electrical parameters.
• RoHS Compliant: Meets RoHS requirements for lead-free assemblies.
