UCZ1K151MNJ1MS

The UCZ1K151MNJ1MS is a chip‑type aluminum electrolytic capacitor designed for high‑temperature operation up to +125°C. This surface‑mount, can‑style capacitor provides 150 µF at 80 V with AEC‑Q200 qualification and RoHS compliance for demanding environments.

Engineered for automatic assembly (carrier‑tape fed), the part targets automotive and high‑temperature industrial electronics where stable capacitance, defined ESR at low temperature, and long endurance are required.

Key Features

• Electrical Performance — 150 µF nominal capacitance at 80 V with ±20% tolerance; polarized design suitable for power filtering and energy storage.
• High‑Temperature Rating — Rated for operation from −40 °C to +125 °C, supporting elevated ambient applications.
• Low‑Temperature ESR Specification — ESR specified as 280 mΩ at 100 kHz and includes ESR measurement after the −40 °C test to ensure low‑temperature reliability.
• Endurance — Designed for 3000 hours at 125 °C (endurance rating for this size class), providing predictable life in high‑temperature duty.
• Ripple Current Capability — Rated ripple current of 350 mA at 120 Hz and 700 mA at 10 kHz for effective ripple handling across common power frequencies.
• Surface‑Mount, Chip‑Type Package — Can‑style SMD/chip form factor with a compact footprint (1.35 × 1.25 cm) and landed pad recommendation of 1.28 × 1.28 cm for PCB layout.
• Assembly Ready — Applicable to automatic mounting machines fed with carrier tape for efficient high‑volume assembly.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), addressing industry reliability and environmental directives.

Typical Applications

• Automotive Electronics — Power filtering and energy decoupling in electronic control units and onboard modules where AEC‑Q200 qualification is required.
• Power Supply Modules — Bulk and smoothing capacitor for DC‑DC converters and power conditioning circuits operating at elevated temperatures.
• Industrial Control — Capacitor for motor drivers, sensors, and control electronics deployed in high‑temperature industrial environments.

Unique Advantages

• High‑Temperature Endurance: 3000 hours at 125 °C provides designers with a quantified life metric for elevated‑temperature applications.
• Verified Low‑Temperature ESR: ESR specified at 280 mΩ (100 kHz) with additional verification after −40 °C testing ensures predictable performance across the full −40 °C to +125 °C range.
• Assembly Efficiency: Carrier‑tape compatibility enables straightforward integration into automated surface‑mount production lines.
• Robust Ripple Handling: Dual ripple current ratings (350 mA at 120 Hz; 700 mA at 10 kHz) support a range of switching and line‑frequency applications.
• Industry Qualification: AEC‑Q200 qualification and RoHS compliance simplify selection for regulated and automotive programs.
