UYA1J881MNS1MS

The UYA1J881MNS1MS is a chip-type aluminum electrolytic capacitor in Nichicon’s UYA series, designed for surface-mount assembly and automated placement. It provides a high capacitance of 880 µF at a 63 V rating with extended load life performance for demanding thermal environments.

Engineered for applications that demand long-term reliability, the device is AEC-Q200 qualified, RoHS compliant, and rated for continuous operation up to +125°C with a guaranteed endurance of 5000 hours at that temperature. The part is supplied in carrier-tape compatible packaging for automated mounting.

Key Features

• Capacitance & Voltage — 880 µF nominal capacitance at a 63 V rated voltage with ±20% tolerance, suitable for designs requiring substantial bulk capacitance on a compact SMD footprint.
• High-temperature Endurance — Extended load life: 5000 hours at +125°C. Endurance criteria specify capacitance change within ±30%, tan δ within 300% of initial, and leakage current not exceeding the initial specified value after the endurance test.
• Operating Temperature Range — Rated for −40°C to +125°C operation to support high-temperature system environments.
• Electrical Characteristics — Leakage current specification: after 2 minutes at rated voltage and 20°C, leakage ≤ 0.01CV or 3 µA (whichever is greater). Rated tan δ (max.) at 120 Hz for 63 V is 0.12.
• Ripple Current Capability — 800 mA at 120 Hz (low frequency) and 1.6 A at 10 kHz (high frequency), providing defined ripple handling across common power-conversion frequencies.
• Package & Mounting — Chip-type, radial can SMD package designed for surface-mount applications; compatible with carrier-tape fed automated mounting machines. Physical size: approximately 2.15 × 1.8 cm (L × D).
• Qualification & Compliance — AEC-Q200 Qualified and compliant with the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulated production requirements.

Typical Applications

• Automotive Electronics — Suitable for automotive electronic modules that require AEC-Q200 qualification and sustained operation at elevated temperatures up to +125°C.
• High-temperature Power Modules — For surface-mount power systems where extended load life at +125°C and a 63 V rating are required.
• Automated PCB Assembly — Carrier-tape compatible chip-type packaging enables reliable placement on automated surface-mount lines for volume production.

Unique Advantages

• Long-term thermal reliability — 5000 hours endurance at +125°C provides predictable performance in sustained high-temperature use.
• Automated assembly ready — Carrier-tape compatible chip form factor simplifies high-volume surface-mount production and reduces assembly handling complexity.
• Defined ripple performance — Specified ripple current at both 120 Hz and 10 kHz enables designers to evaluate behavior across typical power-conversion frequencies.
• Qualification for automotive environments — AEC-Q200 qualification supports inclusion in automotive-grade designs where that certification is required.
• Regulatory compliance — RoHS compliance aligns the component with common environmental directives for modern electronics manufacturing.
