LGU2Z561MELY

The LGU2Z561MELY is a snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LGU series, specified for 180 V and 560 µF nominal capacitance with ±20% tolerance. Designed for general‑purpose power applications, it delivers high ripple‑current capability and long endurance for systems operated up to 105°C.

Packaged in a radial can with snap‑in mounting and supplied in tray packing, this part is in mass production and RoHS‑compliant, making it suitable for production designs that require stable bulk capacitance and reliable thermal performance.

Key Features

• Rated Voltage: 180 V — suitable for higher‑voltage DC rails where 180 V tolerance is required.
• Capacitance & Tolerance: 560 µF with ±20% tolerance at 120 Hz, 20°C for predictable bulk energy storage and filtering.
• Low Loss (tan δ): tanδ ≤ 0.15 measured at 120 Hz and 20°C, supporting efficient charge/discharge behavior.
• High Ripple‑Current Capability: 1.55 A at 120 Hz (low frequency) and 2.325 A at 50 kHz (high frequency) for robust handling of AC ripple on DC rails.
• Leakage Current: 950 µA (specified) to help quantify standby losses and bias requirements.
• Endurance: 3000 hours at 105°C with rated ripple current applied, meeting the LGU series endurance specification for long‑term stability.
• Operating Temperature Range: −40°C to +105°C for wide environmental applicability.
• Package & Mounting: φ20 × 45 mm can (L: 4.5 cm × D: 2 cm), snap‑in radial package supplied in trays for production assembly.
• Regulatory: RoHS‑compliant.

Typical Applications

• Power Supply Filtering: Bulk smoothing and ripple reduction on 180 V DC rails where 560 µF and high ripple current capability are required.
• Industrial Power Electronics: Energy buffering and decoupling in industrial converters and control equipment that operate across −40°C to +105°C.
• General‑Purpose DC Systems: General bulk capacitance for higher‑voltage electronic systems needing predictable leakage and endurance over extended operating periods.

Unique Advantages

• High Voltage Rating with Substantial Capacitance: 180 V and 560 µF combine to provide significant stored energy without resorting to larger form factors.
• Measured Low Loss: tanδ ≤ 0.15 at 120 Hz and 20°C, enabling efficient performance in AC ripple environments.
• Proven Ripple Handling: Specified 1.55 A (120 Hz) and 2.325 A (50 kHz) ripple currents support both low‑ and high‑frequency ripple demands.
• Long Endurance at Elevated Temperature: 3000 hours at 105°C under rated ripple current ensures sustained performance in thermally demanding applications.
• Production‑Ready Packaging: Tray packing and mass production status simplify BOM planning and assembly for volume programs.
• Regulatory Compliance: RoHS‑compliant for global design requirements.
