UUA1A471MNL1GS

The UUA1A471MNL1GS from Nichicon is a surface mount aluminum electrolytic capacitor in the UUA series, offering 470 µF capacitance at a 10 V rating. Engineered as a chip-type, long-life SMD can, it targets applications requiring high capacitance density in a compact φ10 × 10 mm package with embossed carrier taping for automated placement.

Designed for demanding environments, this capacitor combines a wide operating temperature range and long endurance to support robust power decoupling, smoothing and bulk energy storage in electronic modules.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low-loss Characteristic — Tangent of loss angle (tan δ) of 0.24 measured at 120 Hz and 20°C for the 10 V rating, supporting low dissipation in filtering applications.
• Ripple Current Handling — Specified low-frequency ripple current of 320 mA at 120 Hz and high-frequency ripple current of 480 mA at 10 kHz to support both mains-frequency and switching-power applications.
• Leakage and Endurance — Leakage current specified at 47 µA and a rated life of 5000 hours at 105°C, enabling long-term stability under elevated-temperature conditions.
• Temperature Range — Wide operating temperature span from −55°C to +105°C for use across harsh ambient conditions.
• Package and Mounting — φ10 × 10L radial can in an SMD configuration; supplied in embossed carrier taping for pick-and-place assembly. Surface mount land recommendation: 10.3 mm × 10.3 mm.
• Quality and Compliance — AEC-Q200 qualified and RoHS compliant, meeting industry reliability and environmental requirements.

Typical Applications

• Automotive Electronic Modules — Suitable for module-level smoothing and bulk storage where an AEC-Q200 qualified SMD electrolytic capacitor is required.
• Power Supply Filtering — Used for bulk filtering and ripple suppression in low-voltage power rails with both low- and high-frequency ripple currents specified.
• Embedded and Industrial Electronics — Provides stable capacitance and long life for control boards and power management circuits operating across −55°C to +105°C.

Unique Advantages

• High Capacitance in a Compact SMD Can — 470 µF in a φ10 × 10 mm package allows designers to reduce board area compared with larger through-hole alternatives.
• Long Endurance at Elevated Temperature — 5000 hours at 105°C provides predictable life characteristics for designs exposed to sustained high temperatures.
• Dual Ripple Performance — Specified ripple current at both 120 Hz and 10 kHz makes the part versatile for linear and switching power applications.
• AEC-Q200 Qualification — Provides an explicit reliability credential for designs that require industry-level component qualification.
• Manufacturing-friendly Packaging — Embossed carrier taping supports automated surface-mount assembly and throughput.
