UCZ1E821MNJ1MS

The UCZ1E821MNJ1MS is a surface-mount aluminum electrolytic capacitor from Nichicon's UCZ series, offered in a compact chip-style can (φ12.5 × 13.5L). It delivers 820 µF at 25 V with polarized construction for use in demanding thermal and vibration environments.

Designed for high-temperature operation and automated assembly, this part targets applications that require high capacitance, controlled ESR, and extended endurance up to +125°C. The device is AEC-Q200 qualified and RoHS compliant for reliability-focused designs.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with ±20% tolerance at 25 V rated voltage, providing bulk energy storage in a single SMD can.
• High-Temperature Capability: Operating temperature range −40°C to +125°C and rated endurance of 3000 hours at 125°C for the φ12.5 case size.
• Low ESR & Ripple Handling: ESR 60 mΩ (measured at 20°C, 100 kHz) with ripple current ratings of 850 mA at 120 Hz and 1.7 A at 10 kHz, enabling stable performance under AC stress.
• Leakage & Loss: Specified leakage current of 205 µA and loss characteristics consistent with electrolytic performance at rated conditions.
• Surface-Mount Package & Assembly: Chip-type radial can in SMD format (φ12.5 × 13.5L) with embossed carrier taping for automatic pick-and-place mounting and high-volume production.
• Reliability & Compliance: AEC-Q200 qualified and RoHS compliant, supporting use where automotive-grade qualification and environmental compliance are required.

Typical Applications

• Automotive Electronic Modules: Suitable for automotive power and control modules where AEC-Q200 qualification and operation to +125°C are required.
• High-Temperature Power Supplies: Bulk capacitance and low ESR make this part appropriate for power supply filtering in high-temperature environments.
• Mass-Production SMT Assemblies: Embossed carrier taping and chip-type SMD can packaging simplify automated assembly and placement in production lines.

Unique Advantages

• High capacitance in a compact SMD can: 820 µF in a φ12.5 × 13.5L package reduces the need for multiple discrete capacitors.
• Extended high-temperature endurance: Rated for 3000 hours at 125°C, supporting long-term use in hot operating environments.
• Predictable ripple performance: Defined ripple current ratings (850 mA at 120 Hz; 1.7 A at 10 kHz) combined with 60 mΩ ESR provide measurable AC handling capability.
• Automated assembly-ready: Embossed carrier taping and SMD form factor enable efficient pick-and-place integration.
• Industry qualification and compliance: AEC-Q200 qualification and RoHS compliance support regulated designs and supply-chain requirements.
