LGU2Z182MELC

The LGU2Z182MELC is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 1.8 mF capacitance at a 180 V rating in a radial, can-style snap‑in package with a φ35 × 45 mm footprint and tray packing for volume assembly.

Key value comes from high ripple handling, extended endurance at elevated temperature, and wide ambient operating range, making it suitable for designs that require sustained performance under continuous DC bias and ripple conditions.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 180 V with ±20% tolerance, providing substantial bulk capacitance for energy storage and smoothing.
• High ripple current capability — 3.3 A at 120 Hz (low frequency) and 4.95 A at 50 kHz (high frequency), enabling effective handling of both mains‑frequency and higher‑frequency ripple currents.
• Endurance at elevated temperature — 3000 hours life at 105°C when subjected to rated DC bias plus rated ripple current, meeting long‑term reliability requirements under thermal stress.
• Loss characteristics — tan δ of 0.15 at 20°C and 120 Hz for the 160–420 V class, specifying dissipation factor for AC performance evaluation.
• Leakage current — specified leakage current of 1700 µA, measured after standard voltage application, for predictable standby and quiescent behavior.
• Wide operating temperature — −40°C to +105°C category temperature range, supporting a broad set of environmental conditions.
• Package & mounting — radial, snap‑in can (φ35 × 45 mm), designed for secure snap‑in board mounting and tray packing for production workflows.
• RoHS compliant — meets RoHS directive requirements for restricted substances.

Typical Applications

• General purpose power systems — Specified as a general purpose component; suitable where 1.8 mF at 180 V and robust ripple capability are required.
• High‑temperature environments — Applications that demand sustained performance at elevated ambient temperatures up to 105°C, leveraging the 3000‑hour endurance specification.
• Bulk energy storage and smoothing — Designs needing significant capacitance and defined leakage/tan δ characteristics for DC bias and ripple handling.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 3.3 A (120 Hz) and 4.95 A (50 kHz) allow predictable handling of both low‑ and high‑frequency ripple without overstressing the capacitor.
• Extended high‑temperature life: Endurance specified at 3000 hours at 105°C under rated conditions supports long‑term reliability in thermally demanding designs.
• Clear electrical characterization: Specified tan δ (0.15 at 120 Hz, 20°C for this voltage class) and defined leakage current (1700 µA) enable accurate modeling of loss and standby behavior.
• Robust mounting option: Snap‑in radial can package (φ35 × 45 mm) for secure board installation and efficient tray packing for production volumes.
• Wide ambient range: −40°C to +105°C operating temperature range covers a broad set of environmental conditions encountered in industrial and power electronics.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted‑substance adherence.
