LGU2Z152MELB

The LGU2Z152MELB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series designed for general-purpose power applications. It provides 1500 µF capacitance at a 180 V rating in a compact φ30 × 45 mm can with snap-in mounting and tray packing for production deployment.

Engineered for sustained operation at elevated temperatures, this part delivers long endurance under rated ripple conditions (3000 hours at 105°C), notable ripple-current capability across low and high frequencies, and RoHS-compliant construction for industrial and commercial designs.

Key Features

• Capacitance & Voltage — 1500 µF nominal capacitance with a 180 V rated voltage and ±20% capacitance tolerance for predictable bulk energy storage.
• High-temperature Endurance — Rated for operation from −40°C to 105°C with a 3000-hour endurance at 105°C when subjected to D.C. bias plus rated ripple current.
• Ripple Current Capability — Low-frequency ripple current of 2.9 A at 120 Hz and high-frequency ripple current of 4.35 A at 100 kHz to support filtering and DC-link duties across frequency ranges.
• Electrical Loss Characteristic — tanδ (loss tangent) of 0.15 measured at 20°C, 120 Hz, enabling designers to assess dissipation under test conditions.
• Leakage Current — Specified leakage current of 1550 µA (measured after rated voltage application), supporting reliability planning and bias budgeting.
• Form Factor & Mounting — Radial, can-type snap-in package (φ30 × 45 mm) for robust board mounting and easy assembly; supplied in tray packing and available in mass production quantities.
• Regulatory — RoHS compliant.

Typical Applications

• Industrial power supplies — Bulk smoothing and DC-link filtering on 180 V rails where sustained ripple handling and 105°C endurance are required.
• Motor drives and inverters — DC-link and filter capacitors benefiting from the part’s high ripple-current capability at both low and high frequencies.
• UPS and power backup systems — Energy storage and smoothing for hold-up and transient control thanks to high capacitance and rated voltage.
• General-purpose electronic equipment — Board-level bulk decoupling and power-conditioning in industrial and commercial devices that require robust thermal and ripple performance.

Unique Advantages

• Sustained performance at elevated temperature — 3000-hour endurance at 105°C under rated ripple current supports long-term reliability planning in hot environments.
• Broad ripple handling across frequencies — Specified ripple currents at 120 Hz and 100 kHz allow designers to size capacitors for both mains-frequency and switching-frequency applications.
• High-voltage capability in a compact can — 180 V rating combined with 1500 µF capacitance in a φ30 × 45 mm package reduces system size while meeting voltage requirements.
• Predictable dissipation and leakage — Specified tanδ and leakage current figures enable accurate thermal and bias budget calculations.
• Production-ready supply — Tray packing and mass-production status simplify procurement and manufacturing integration.
• Regulatory compliance — RoHS compliance supports use in regulated product lines.
