Overview of UCZ1H681MNQ1MS – 680 µF, 50 V Surface-Mount Aluminum Electrolytic Capacitor

The UCZ1H681MNQ1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly. It delivers 680 µF of capacitance at 50 V in a compact φ18 × 16.5 mm can, engineered for reliable operation across a wide temperature range.

Targeted at demanding environments, this part provides high-temperature endurance and defined low-temperature ESR behavior, making it suitable for applications that require stable bulk capacitance and ripple handling up to +125°C. It is AEC-Q200 qualified and RoHS compliant.

Key Features

  • Electrical Performance 680 µF nominal capacitance with ±20% tolerance and tanδ of 0.16 (measured at 20°C, 120 Hz) for predictable AC behavior.
  • Voltage Rating 50 V rated voltage suitable for intermediate-voltage power applications.
  • Ripple Handling & ESR Low-frequency ripple current of 1.05 A (120 Hz) and high-frequency ripple current of 2.1 A (10 kHz) with ESR of 78 mΩ measured at 20°C/100 kHz.
  • Thermal Range & Endurance Operating temperature from −40°C to +125°C and an endurance specification of 3500 hours at 125°C for sustained high-temperature performance.
  • Surface-Mount Package Chip-type radial can in a surface-mount form factor (φ18 × 16.5L) supplied on embossed carrier tape for automated placement.
  • Reliability & Compliance AEC-Q200 qualified and RoHS compliant, supporting designs that require documented component-level reliability and environmental compliance.

Typical Applications

  • Automotive Electronics Suitable for electronic modules where AEC-Q200 qualification and −40°C to +125°C operation are required.
  • High-Temperature Electronics Bulk capacitance solution for systems that operate or are stored at elevated temperatures up to +125°C.
  • Automated Surface-Mount Production Designed for use with automatic mounting machines and supplied on embossed carrier tape to streamline high-volume assembly.

Unique Advantages

  • High Bulk Capacitance in a Compact Can: 680 µF in a φ18 × 16.5 mm package provides significant energy storage while minimizing board area compared with larger through-hole parts.
  • Defined Low-Temperature ESR: ESR specified at −40°C supports designs that need predictable impedance across extreme cold-to-hot transitions.
  • Robust Ripple Performance: Rated ripple currents of 1.05 A (120 Hz) and 2.1 A (10 kHz) combined with 78 mΩ ESR help manage AC stress in power rails and decoupling tasks.
  • High-Temperature Endurance: 3500 hours endurance at 125°C provides a quantifiable reliability metric for thermal-stressed designs.
  • Manufacturing-Friendly Packaging: Embossed carrier tape format enables automated placement and consistent throughput on SMT lines.
  • Industry Qualification & Compliance: AEC-Q200 qualification and RoHS compliance reduce integration risk and simplify regulatory tracking.
