LGU2D561MELB

The LGU2D561MELB is a snap-in terminal type aluminum electrolytic capacitor from Nichicon’s LGU series, designed for general-purpose power applications. It delivers 560 µF at a rated voltage of 200 V in a compact φ30 × 25 mm can with a snap-in radial mounting.

Engineered for high-temperature operation up to 105°C and long-term endurance, this part provides defined ripple-handling capability and stable electrical characteristics suitable for industrial and power-electronics designs that require robust bulk capacitance and reliable service life.

Key Features

• Electrical Capacity and Voltage — 560 µF nominal capacitance with a rated voltage of 200 V and a capacitance tolerance of −20% to +20%.
• High-Temperature Endurance — Rated for 3000 hours at 105°C under rated ripple current conditions as specified by the LGU series endurance test.
• Ripple Current Performance — Low-frequency ripple current of 1.67 A (120 Hz) and high-frequency ripple current of 2.505 A (50 kHz) to support circuits with significant AC stress on the capacitor.
• Loss and Leakage — Dissipation factor (tan δ) of 0.15 measured at 20°C, 120 Hz, and a leakage current specified at 1000 μA.
• Temperature Range — Operates over −40°C to +105°C, meeting the LGU series category temperature range for 16 to 250 V parts.
• Mechanical / Mounting — Snap-in radial can package (φ30 × 25 mm) packaged in trays for handling and assembly.
• RoHS Compliant — Meets RoHS directive requirements as indicated for the LGU series.

Typical Applications

• General-purpose power filtering — 560 µF at 200 V provides bulk capacitance for smoothing and filtering in power supply circuits for industrial and commercial equipment.
• Industrial power electronics — Designed for sustained ripple stress and 3000 h endurance at 105°C, suitable for assemblies exposed to elevated operating temperatures.
• DC bus and energy storage — Compact snap-in can and substantial capacitance make it useful for DC bus stabilization and short-term energy buffering.

Unique Advantages

• Long-duration high-temperature operation: 3000-hour endurance at 105°C provides predictable aging characteristics for designs requiring extended life under elevated temperatures.
• Defined ripple capability: Specified low- and high-frequency ripple current ratings (1.67 A @120 Hz, 2.505 A @50 kHz) let engineers size capacitance for real-world AC stress conditions.
• Compact snap-in form factor: φ30 × 25 mm radial can with snap-in terminals offers high capacitance density in a board-mountable package for robust mechanical retention.
• Measured loss and leakage: Known dissipation factor (tan δ = 0.15 at 20°C, 120 Hz) and a defined leakage current (1000 μA) enable confident thermal and circuit design calculations.
• RoHS compliance: Conforms to RoHS requirements, supporting environmental and regulatory needs for assembled products.
• Production availability: Mass production status and tray packing support volume procurement and automated assembly workflows.
