UWF1A470MCL1GB

The UWF1A470MCL1GB is a surface-mount aluminum electrolytic capacitor in Nichicon's UWF series, optimized as a low-impedance chip type for high-density PCB assembly. It offers 47 µF capacitance at a 10 V rating with a compact φ6.3 × 5.4 mm can-style SMD package and embossed carrier taping for automated placement.

Key value comes from its wide operating temperature range (−55 °C to +105 °C), AEC-Q200 rating, RoHS compliance, and a specified endurance of 1000 hours at 105 °C—making it suitable for demanding electronic environments. Note: this part is marked End Of Life and scheduled for discontinuation.

Key Features

• Electrical Performance 47 µF nominal capacitance with ±20% tolerance and an impedance of 1.3 Ω; tangent of loss angle (tan δ) is 0.19 at 20 °C, 120 Hz (rated 10 V).
• Voltage Rating Rated for 10 V operation, with leakage current specified at 4.7 µA under standard test conditions.
• Ripple Handling Specified ripple capability of 57.5 mA at 120 Hz and 115 mA at 10 kHz to support decoupling and smoothing in power rails.
• Reliability & Endurance Endurance specified as 1000 hours at 105 °C with defined limits for capacitance change, tan δ, and leakage current.
• Temperature Range Rated for operation from −55 °C to +105 °C for applications with elevated ambient or junction temperatures.
• Package & Assembly Compact φ6.3 × 5.4 mm radial can SMD (chip type) with surface-mount land size 6.6 × 6.6 mm; supplied in embossed carrier taping compatible with automated placement.
• Standards & Compliance AEC-Q200 listed rating and RoHS compliant as provided in the product data.

Typical Applications

• Automotive electronics — AEC-Q200 rating and a −55 °C to +105 °C operating range suit filtering and decoupling in vehicle electronic modules where elevated temperatures occur.
• High-density PCB power decoupling — Compact chip-style can and embossed taping enable automated placement for decoupling on space-constrained boards.
• Power supply smoothing — Low impedance and defined ripple current ratings make this capacitor appropriate for local smoothing on 10 V rails.
• Industrial control electronics — Endurance of 1000 hours at 105 °C supports designs exposed to sustained elevated temperatures.

Unique Advantages

• Low-impedance chip construction: Provides improved AC performance for decoupling and smoothing compared with standard radial types, with an impedance of 1.3 Ω at specified conditions.
• Compact SMD form factor: φ6.3 × 5.4 mm can-style package and embossed tape packaging enable automated assembly on high-density PCBs.
• High-temperature endurance: Rated for 1000 hours at 105 °C, giving predictable performance in elevated-temperature applications.
• Defined ripple capability: Explicit low- and high-frequency ripple current specifications (57.5 mA at 120 Hz, 115 mA at 10 kHz) help optimize power-stage designs.
• Standards compliance: AEC-Q200 listing and RoHS compliance provide traceable qualification and environmental conformity for regulated designs.
• Controlled dielectric loss: tan δ specified at 0.19 (20 °C, 120 Hz) for predictable dissipation characteristics in frequency-sensitive circuits.
