UUA1H4R7MCL1GS

The UUA1H4R7MCL1GS is a surface-mount aluminum electrolytic chip capacitor in Nichicon's UUA series, specified at 4.7 µF and 50 V with ±20% tolerance. It is a chip-type part designed for high-density PCB assembly and long-life operation, offering AEC-Q200 qualification and RoHS compliance for demanding applications.

Key value propositions include long life at elevated temperature (3000 hours at 105°C), low leakage and loss characteristics, and a compact SMD can package (φ5 × 5.8 mm) optimized for automated placement (embossed carrier taping).

Key Features

• Capacitance & Voltage — 4.7 µF rated capacitance with a 50 V working voltage and ±20% tolerance at 120 Hz, 20°C.
• Electrical Performance — Low tangent of loss angle: tanδ 0.12 (max) at 120 Hz and 20°C for the 50 V rating; leakage current specified at 3 µA (after 2 minutes at rated voltage, 20°C).
• Ripple Current — 22 mA low-frequency ripple current at 120 Hz and 20°C, and 33 mA high-frequency ripple current at 10 kHz and 20°C, suitable for decoupling and smoothing roles on SMD boards.
• Long-Life Endurance — Rated for 3000 hours at 105°C (load life for the chip-type sizes noted), with endurance characteristics defined for capacitance, tanδ and leakage after life testing.
• Temperature Range — Operating temperature range from −55°C to +105°C to support wide environmental conditions.
• Package & Assembly — Chip-type SMD can package, size φ5 × 5.8 mm, surface-mount land recommendation L: 5.3 × W: 5.3 mm, and supplied in embossed carrier tape for automated placement.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant; marked with black print on the case top per specification.
• Polarized — Polar type aluminum electrolytic construction for applications requiring polarity awareness.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and a 3000 h life at 105°C make this capacitor suitable for automotive electronic modules that require long-life SMD capacitors.
• High-Density PCBs — Chip-type SMD can and embossed carrier taping support automated placement on compact, high-density circuit boards.
• High-Temperature Environments — The −55°C to +105°C operating range and defined endurance at 105°C address applications exposed to wide temperature swings.

Unique Advantages

• Long-life assurance: Specified 3000 hours at 105°C provides predictable endurance for constrained maintenance cycles.
• Automotive-grade qualification: AEC-Q200 rating supports use in designs where automotive component qualification is required.
• Low leakage and loss: Leakage current of 3 µA and tanδ 0.12 at 120 Hz (50 V) help preserve efficiency and minimize standby losses.
• SMD-ready package: Compact φ5 × 5.8 mm can with embossed carrier taping streamlines pick-and-place assembly on automated lines.
• Wide temperature capability: −55°C to +105°C operation enables deployment across harsh thermal environments.
