LGGW6561MELC40

The LGGW6561MELC40 is a Nichicon LGG series snap-in aluminum electrolytic capacitor designed for general-purpose power applications. It combines a 560 µF capacitance with a 420 V rating in a compact snap-in radial can package intended to support equipment downsizing.

Engineered for robust operation, this capacitor offers high ripple-current capability, low leakage, and extended endurance at elevated temperatures, making it suitable for industrial and power-electronics environments requiring reliable bulk capacitance.

Key Features

• Capacitance & Voltage: 560 µF capacitance with a 420 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Snap-In Radial Can Package: Snap-in terminal type in a radial, can-style package (φ35 × 40 mm) for secure board mounting and mechanical stability.
• High Ripple Current Capability: Rated ripple current of 1.9 A at 120 Hz (low frequency) and 2.717 A at 100 kHz (high frequency) to handle AC ripple in power circuits.
• Low Leakage: Specified leakage current of 1450 µA after application of rated voltage at 20°C.
• Extended Endurance at Elevated Temperature: 2000 hours endurance at 105°C with defined limits for capacitance change, tan δ, and leakage current.
• Wide Operating Temperature Range: Rated for operation from −25°C to +105°C (for 400 V range), suitable for demanding thermal environments.
• RoHS Compliant: Meets RoHS requirements for environmental compliance.
• Designed for Downsizing: LGG series offers one rank smaller case size than LGN, helping reduce overall equipment footprint.

Typical Applications

• Industrial Power Supplies: Provides bulk capacitance and ripple handling for general-purpose industrial power systems where a 420 V-rated capacitor is required.
• Power Conversion Modules: Suitable for energy storage and smoothing in general-purpose converter and inverter modules, leveraging its high ripple-current ratings.
• Compact Electronic Equipment: The smaller LGG case size and snap-in mounting support equipment downsizing while maintaining required capacitance and voltage margin.
• High-Temperature Environments: Rated for continuous operation up to 105°C with a 2000-hour endurance specification for reliable performance under elevated temperatures.

Unique Advantages

• High Voltage Capability: 420 V rating enables use in higher-voltage general-purpose applications without series stacking.
• Robust Ripple Handling: 1.9 A (120 Hz) and 2.717 A (100 kHz) ripple current ratings reduce thermal stress during AC loading conditions.
• Long Endurance at 105°C: 2000-hour life at 105°C offers predictable aging characteristics for designs exposed to sustained heat.
• Compact Snap-In Form Factor: φ35 × 40 mm size and snap-in terminals combine space savings with secure PCB retention.
• Low Standby Leakage: 1450 µA leakage current specification supports designs where minimized leakage is important after voltage application.
• Production-Ready Packaging: Tray packing and mass production availability streamline procurement and assembly for volume designs.
