UUE1C331MNS1MS

The UUE1C331MNS1MS is a chip-type aluminum electrolytic capacitor from Nichicon’s UUE series, specified for demanding environments and continuous operation at elevated temperatures. It is a polarized, surface-mount component designed for applications that require long-term high-temperature endurance and vibration resistance.

Key value comes from its 330 µF capacitance at 16 V rating, AEC-Q200 qualification, RoHS compliance, and an endurance rating of 5000 hours at 125°C—properties that suit automotive electronics and other high-temperature electronic assemblies.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance.
• High‑Temperature Endurance — Rated for operation from −55 °C to +125 °C with a specified load life of 5000 hours at 125 °C.
• AEC‑Q200 Qualified — Meets AEC‑Q200 qualification as noted in the product data for demanding service conditions.
• RoHS Compliance — Conforms to the RoHS directive (2011/65/EU.(EU)2015/863).
• Low Leakage — Leakage current specified as not more than 0.03CV (µA) after 1 minute’s application of rated voltage at 20 °C.
• Ripple Current Capability — Rated ripple handling of 502.5 mA at 120 Hz (low frequency) and 750 mA at 10 kHz (high frequency) for the 330 µF, 16 V part.
• Surface‑Mount Chip Package — Chip-type, surface-mount radial can (SMD) package with case size 12.5 × 13.5 mm and a recommended land size of 12.8 × 12.8 mm.
• Endurance & Stability — After endurance testing (5000 hours at 125 °C) capacitance change is within ±30%, tan δ remains within specified limits, and leakage current meets initial specification.

Typical Applications

• Automotive Electronics — Suited for automobile electronics where heavy-duty, long-life performance at elevated temperatures is required.
• High‑Temperature PCB Assemblies — Designed for assemblies and processes that expose components to elevated temperatures up to 125 °C.
• Surface‑Mount Power Modules — For SMD power assemblies requiring a compact chip-type aluminum electrolytic capacitor with defined ripple capability.

Unique Advantages

• Extended high‑temperature life: 5000 hours at 125 °C provides predictable long-term performance in elevated-temperature environments.
• Automotive‑grade qualification: AEC‑Q200 qualification supports use in designs that require industry-recognized reliability standards.
• Measurable ripple handling: Specified ripple current of 502.5 mA (120 Hz) and 750 mA (10 kHz) for the 330 µF, 16 V part enables selection based on application frequency.
• Low standby leakage: Leakage current limit of 0.03CV (µA) after 1 minute at 20 °C helps maintain predictable leakage behavior in low-current designs.
• Compact SMD form factor: Chip-type radial can in a 12.5 × 13.5 mm case with a defined land pattern simplifies layout for space-constrained boards.
• Regulatory compliance: RoHS conformity reduces material compliance work for regulated markets.
