UCZ1K271MNS1MS

The UCZ1K271MNS1MS is a surface-mount aluminum electrolytic capacitor from Nichicon’s UCZ series, offering 270 µF capacitance at an 80 V rating with high-temperature endurance. Designed for demanding electronic power systems, it combines high voltage capability, low-temperature ESR control, and long life at elevated temperatures.

Targeted at designs that require robust bulk capacitance and stable high-frequency behavior, this part addresses applications where wide operating temperature, vibration resistance, and component-level qualification are required.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance with an 80 V working voltage and ±20% tolerance, providing substantial energy storage for high-voltage power rails.
• Wide Temperature Range & Endurance — Specified for −40°C to +125°C operation with an endurance rating of 3500 hours at 125°C, supporting long-term use in high-temperature environments.
• Low-Frequency and High-Frequency Ripple Handling — Rated ripple currents of 500 mA at 120 Hz and 1.0 A at 100 kHz enable both low-frequency smoothing and high-frequency switching regulator support.
• Controlled ESR and Loss Tangent — ESR of 190 mΩ measured at 20°C/100 kHz and tanδ of 0.12 (measured at 20°C/120 Hz) for predictable AC performance in filter and decoupling roles.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant, with vibration resistance and soldering-heat robustness per UCZ series specifications.
• Surface-Mount Packaging — Chip-type radial can SMD in embossed carrier taping suitable for automated placement; nominal size φ16 × 16.5L for compact board integration.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and −40°C to +125°C rating make this capacitor suitable for automotive power modules, control units, and voltage rails that require reliable bulk capacitance.
• High-voltage power supplies — 80 V rating and 270 µF capacitance provide bulk energy storage and filtering for high-voltage DC rails and power distribution networks.
• Switching regulator output stages — Low ESR (190 mΩ at 100 kHz) and 1.0 A high-frequency ripple current rating support stable output filtering on DC‑DC converters and switching supplies.
• Industrial controls and power electronics — Extended temperature endurance and vibration resistance suit applications in demanding industrial environments and motor-drive electronics.

Unique Advantages

• High-voltage bulk capacitance: 270 µF at 80 V supplies significant energy buffering for high-voltage rails without increasing part count.
• Designed for high-temperature operation: Rated to +125°C with a 3500-hour endurance at that temperature, enabling reliable performance in elevated-temperature assemblies.
• Predictable AC performance: Specified ESR at 100 kHz and tanδ at 120 Hz give engineers measurable parameters for filter and stability design.
• Automotive-grade qualification: AEC‑Q200 status supports use in automotive systems where component-level qualification is required.
• Assembly-ready SMD format: Embossed carrier taping and chip-style can packaging facilitate automated placement for volume manufacturing.
