LGU2Z471MELA

The LGU2Z471MELA is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal format. It provides 470 µF nominal capacitance at a rated voltage of 180 V with ±20% tolerance and is specified for general‑purpose applications.

Engineered for sustained operation up to 105°C, this snap‑in can delivers robust ripple handling and long endurance (3000 hours at 105°C), making it suitable for equipment that requires reliable high‑voltage bulk capacitance in a radial, can style package (φ25 × 30L).

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 180 V rated voltage and ±20% tolerance for stable energy storage in high‑voltage circuits.
• High‑Temperature Endurance — Rated lifetime of 3000 hours at 105°C when subjected to rated ripple current and DC bias, supporting prolonged operation in elevated temperature environments.
• Ripple Current Performance — Supports 1500 mA at 120 Hz (low frequency) and 2250 mA at 50 kHz (high frequency), enabling effective smoothing under AC ripple and switching conditions.
• Electrical Loss and Leakage — Specified tanδ (DF) of 0.15 at 20°C and 120 Hz and a leakage current of 870 µA, providing predictable dissipation and low self‑discharge behavior.
• Operating Temperature Range — Rated for −40°C to +105°C to accommodate a wide range of ambient conditions.
• Package & Mounting — Snap‑in (radial, can) termination in a φ25 × 30L body for secure board retention and tray packing for mass production handling.
• Compliance — RoHS‑compliant construction in accordance with the series specification.

Typical Applications

• General Purpose Power Electronics — Use where a 470 µF, 180 V snap‑in capacitor is needed for bulk capacitance in power conversion or filtering circuits.
• Industrial Equipment — Suitable for systems that require sustained ripple handling and high‑temperature endurance up to 105°C.
• Power Supply Modules — Applicable where predictable leakage, dissipation factor, and long life under rated ripple current are important design considerations.

Unique Advantages

• High Voltage Capability: 180 V rating supports higher‑voltage designs without requiring series stacking of lower‑voltage capacitors.
• Long Endurance at Elevated Temperature: 3000 hours life at 105°C provides a measured reliability baseline for thermal‑stress applications.
• Strong Ripple Handling: Specified low‑ and high‑frequency ripple currents (1.5 A at 120 Hz; 2.25 A at 50 kHz) reduce thermal rise and improve smoothing performance under varying switching frequencies.
• Predictable Electrical Characteristics: Specified tanδ (0.15 at 20°C/120 Hz) and defined leakage current (870 µA) enable accurate thermal and leakage budgeting in designs.
• Robust Mechanical Mounting: Snap‑in radial can package (φ25 × 30L) provides secure board retention for production assemblies and automated handling (tray packing).
• Regulatory Compliance: RoHS‑compliant construction supports regulatory requirements for lead‑free manufacturing.
