LGU2Z471MELY

The LGU2Z471MELY is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series, offering 470 µF capacitance at a 180 V rating. It is designed for general-purpose applications that require substantial ripple handling and high-temperature endurance.

With a compact φ20 × 40 mm can and tray packing for production handling, this capacitor combines high ripple-current capability, robust leakage and dissipation characteristics, and a rated lifetime of 3000 hours at 105°C for reliable operation in demanding environments.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 180 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Snap-In Mounting & Package — Snap-in terminal, radial can package (φ20 × 40 mm) optimized for secure board mounting and high-current PCB layouts.
• High Ripple Current Performance — Rated low-frequency ripple current of 1.4 A (120 Hz) and high-frequency ripple current of 2.1 A (50 kHz), enabling effective AC ripple handling across frequency ranges.
• High-Temperature Endurance — Endurance rated for 3000 hours at 105°C under DC bias plus rated ripple current, supporting extended operation at elevated temperatures.
• Low Loss & Leakage — Tangent of loss angle (tan δ) specified at 0.15 (measured at 20°C, 120 Hz) and leakage current listed as 870 µA for stable electrical performance.
• Wide Operating Temperature — Specified operating range from –40°C to 105°C for broad environmental tolerance.
• Compliance & Production — RoHS compliant and available in tray packing; product status: mass production.

Typical Applications

• Power supply filtering — Provides bulk capacitance and ripple handling for general-purpose power supplies and DC bus smoothing where 180 V ratings are required.
• Industrial power electronics — Suited to industrial control and power modules that demand high ripple-current capability and 105°C endurance.
• Energy storage and buffering — Used for local energy buffering in systems requiring 470 µF at elevated temperatures and continuous ripple stress.

Unique Advantages

• Designed for sustained high-temperature operation: 3000-hour endurance at 105°C ensures long-term stability under elevated thermal stress.
• Frequency-capable ripple handling: Dual ripple current ratings (1.4 A at 120 Hz and 2.1 A at 50 kHz) support performance across power-conversion frequency ranges.
• Compact, manufacturable package: φ20 × 40 mm snap-in can with tray packing simplifies board integration and assembly throughput.
• Controlled loss and leakage: tan δ 0.15 and specified leakage current support predictable dissipation and low standby loss in designs.
• Regulatory readiness: RoHS compliance supports use in markets requiring restricted-substance conformance.
