LGU2D182MELC

The LGU2D182MELC is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, specified for general‑purpose power applications. With a rated capacitance of 1800 µF at 200 V, snap‑in mounting and a compact φ35 × 45 mm can, it is designed to deliver bulk energy storage and filtering where high ripple capability and extended life at elevated temperature are required.

Key value propositions include high allowable ripple current, verified endurance at 105°C, and RoHS compliance—attributes that support reliable performance in demanding power circuits and assemblies.

Key Features

• Electrical Performance 1.8 mF (1800 µF) capacitance at 200 V with ±20% tolerance, providing substantial bulk capacitance for smoothing and filtering in power systems.
• High Ripple Capability Rated ripple currents of 3.48 A at 120 Hz (low frequency) and 5.22 A at 50 kHz (high frequency) enable handling of significant AC ripple on DC rails.
• Endurance at Elevated Temperature Engineered to withstand 3000 hours of rated ripple current application at 105°C, meeting the LGU series endurance specification for long‑term thermal and electrical stress.
• Low Loss and Defined Dissipation tanδ (loss tangent) specified at 0.15 (measured at 20°C, 120 Hz) for predictable dissipation characteristics in AC environments.
• Leakage Current Leakage current specified at 1800 µA, measured after rated voltage application, enabling designers to account for self‑discharge and bias conditions.
• Robust Operating Range Operates from −40°C to +105°C (for the 16–250 V range), suitable for many industrial and commercial environments.
• Package and Mounting Radial, can‑style snap‑in package (φ35 × 45 mm) for secure chassis or board mounting and simplified assembly; supplied in tray packing for handling.
• Regulatory RoHS compliant as specified for the LGU series.

Typical Applications

• General‑purpose power filtering — Bulk capacitance and 200 V rating make this capacitor suitable for smoothing and decoupling in general power circuits.
• Power supply smoothing — High ripple current capability and 3000 h endurance at 105°C support long‑term smoothing in power supplies and converters.
• High‑ripple environments — Frequency behavior (frequency coefficients provided in the LGU series data for 160–250 V) helps predict ripple performance across low and high frequencies.
• Board/chassis power assemblies — Snap‑in terminal package offers mechanical stability for mounted power modules and assemblies.

Unique Advantages

• Designed for continuous high‑ripple operation Specified ripple currents and 3000 h endurance at 105°C reduce the need for over‑specifying components in ripple‑intensive designs.
• Predictable thermal performance −40°C to +105°C operating range and defined tanδ at 20°C/120 Hz provide consistent behavior across typical industrial temperatures.
• Compact, serviceable package φ35 × 45 mm snap‑in can balances capacitance with a small footprint and secure mechanical mounting for assemblies.
• RoHS compliance Meets RoHS directive requirements as called out for the LGU series, aiding regulatory compliance for many markets.
• Tray packing for production Tray packing supports organized handling and repeatable placement during assembly processes.
• Measured loss and leakage specifications Defined tanδ and leakage current figures allow accurate thermal and leakage budgeting in designs.
