UUD1E471MNL1GS

The UUD1E471MNL1GS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly on high-density PCBs. It provides 470 µF capacitance at 25 V with ±20% tolerance and is supplied in embossed carrier tape for automated placement.

Engineered for elevated-temperature operation and long life, this part is AEC-Q200 rated and RoHS compliant, with an operating temperature range of −55°C to +105°C and a rated lifetime of 5000 hours at 105°C.

Key Features

• Capacitance & Rated Voltage — 470 µF nominal capacitance with ±20% tolerance at a 25 V rating, suitable for mid-voltage SMD designs.
• Low Impedance — 90 mΩ impedance supports lower AC voltage drop and effective decoupling in compact layouts.
• High Ripple Current — 670 mA at 120 Hz and 1.005 A at 10 kHz for improved handling of both low- and high-frequency ripple.
• Leakage Current — 117.5 µA specified leakage current characteristic to allow predictable bias performance.
• Robust Thermal & Lifetime Performance — Rated for −55°C to +105°C operation and 5000 hours endurance at 105°C.
• AEC‑Q200 Qualified & RoHS Compliant — Automotive-grade qualification and RoHS compliance for regulated environments and long-term programs.
• Surface-Mount Can Package — φ10 × 10 mm can-style SMD with a surface mount land size of 10.3 × 10.3 mm and embossed carrier taping for automated assembly.
• Endurance and Soldering Heat Resistance — Meets endurance specifications after 5000 hours at 105°C and withstands soldering heat conditions per datasheet criteria (250°C, 30 s) with defined limits on capacitance change, tan δ and leakage.

Typical Applications

• Automotive electronic modules — AEC‑Q200 rating and high-temperature life make this capacitor suitable for automotive control and power modules requiring stable bulk capacitance.
• Power supply filtering — Low impedance and specified ripple current ratings support smoothing and bulk energy storage on DC power rails.
• SMD high-density PCB assemblies — Chip-type radial can and embossed carrier taping enable automated placement in compact, high-density board designs.

Unique Advantages

• High ripple handling: Specified ripple current at both 120 Hz (670 mA) and 10 kHz (1.005 A) helps maintain voltage stability across a range of operating frequencies.
• Predictable leakage behavior: Defined leakage current (117.5 µA) supports accurate bias and retention calculations in system designs.
• Extended high-temperature life: 5000 hours at 105°C provides a clear endurance metric for thermal-stressed applications.
• Automotive-grade reliability: AEC‑Q200 qualification and RoHS compliance help meet regulatory and program-level requirements.
• SMD-ready packaging: φ10 × 10 mm can with embossed carrier tape simplifies automated assembly and inventory handling for production volumes.
