UUE1C471MNS1MS

The UUE1C471MNS1MS is a chip‑type aluminum electrolytic capacitor from Nichicon's UUE series, designed for demanding electronics that require vibration resistance and extended high‑temperature endurance. It is a polarized, surface‑mount radial can intended for compact power and decoupling applications.

With a rated capacitance of 470 µF at 16 V, AEC‑Q200 qualification and a 5000‑hour load life at 125°C, this part targets automotive and other heavy‑duty electronic systems that need sustained performance in elevated temperatures. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a rated voltage of 16 V with ±20% tolerance; polarized construction for bulk energy storage and decoupling.
• High‑temperature Endurance — Rated for operation from −55°C to +125°C with a specified load life of 5000 hours at 125°C.
• Automotive Qualification — AEC‑Q200 Qualified, suitable for designs that require automotive‑grade component qualification.
• Ripple Current Performance — Handles 502.5 mA at 120 Hz (low frequency) and 750 mA at 10 kHz (high frequency), supporting demanding ripple conditions.
• Low Leakage & Loss — Leakage current specified as ≤ 0.03CV (µA) after 1 minute at 20°C; tan δ for the 16 V version is 0.18 at 120 Hz, 20°C.
• Compact SMD Chip Package — Radial can, surface‑mount construction with dimensions L: 1.35 × D: 1.25 cm and recommended land size L: 1.28 × W: 1.28 cm for PCB assembly.
• Assembly Compatibility — Chip‑type construction provides vibration resistance and is suitable for high‑temperature reflow assembly processes noted by the product specification.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronic Control Units (ECUs) — Bulk decoupling and smoothing in control modules that must operate reliably at up to 125°C and meet AEC‑Q200 requirements.
• Power Modules and Motor Drives — Energy storage and ripple suppression in power assemblies where sustained ripple currents and elevated temperatures are encountered.
• Sensor and Actuator Electronics — Compact SMD form factor and vibration‑resistant construction make it suitable for sensors, actuators and other in‑vehicle electronics.

Unique Advantages

• Extended high‑temperature life — 5000 hours at 125°C delivers predictable aging behavior for designs that run hot or are exposed to elevated ambient temperatures.
• AEC‑Q200 qualification — Provides the component-level assurance required for many automotive and heavy‑duty designs.
• High ripple handling in a small footprint — Up to 750 mA at high frequency in a compact SMD chip reduces board area while supporting demanding power conditions.
• Low leakage and controlled dissipation — Leakage current and tan δ specifications support stable performance in power‑sensitive applications.
• RoHS compliant — Meets current RoHS directive requirements for environmentally restricted substances.
• Chip form factor with vibration resistance — Designed for surface‑mount assembly while addressing mechanical stress in rugged environments.
