UCZ1K271MNJ1MS

The UCZ1K271MNJ1MS is a chip‑type aluminum electrolytic capacitor designed for surface‑mount assembly and high‑temperature operation up to +125°C. It combines a 270 µF capacitance at 80 V with AEC‑Q200 qualification and RoHS compliance for applications demanding elevated temperature endurance and automotive‑grade reliability.

Engineered for automated production, the part is compatible with carrier‑tape feed for pick‑and‑place processes and includes measured ESR performance after low‑temperature testing to support reliable operation across its full −40°C to +125°C range.

Key Features

• Capacitance and Voltage — 270 µF nominal capacitance rated at 80 V with a tolerance of ±20% (−20% to +20%).
• Wide Temperature Range — Specified operating temperature from −40°C to +125°C to support high‑temperature environments.
• Low‑temperature ESR Characterization — ESR specified after the −40°C test; equivalent series resistance is 190 mΩ measured at 100 kHz.
• Endurance at Elevated Temperature — Rated lifetime of 3500 hours at 125°C, with endurance and leakage current criteria defined in the datasheet.
• Ripple Current Ratings — 500 mA at 120 Hz (low frequency) and 1 A at 10 kHz (high frequency) to support ripple handling in power electronics.
• Surface‑mount, Tape‑fed Package — Chip‑type, radial can SMD package sized L: 1.65 × D: 1.6 cm with recommended land size L: 1.63 × W: 1.63 cm for automated SMT assembly.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU,(EU)2015/863), with defined leakage current limits (≤ 0.01CV μA after 2 minutes at 20°C).

Typical Applications

• Automotive electronics — Suited for automotive ECUs and subsystems that require AEC‑Q200 qualification and stable capacitance at elevated temperatures.
• High‑temperature electronic assemblies — Intended for circuits that must operate reliably up to +125°C, leveraging the part’s specified endurance at temperature.
• Automated surface‑mount production — Designed for carrier‑tape feed and pick‑and‑place lines to streamline high‑volume SMT assembly.

Unique Advantages

• High‑temperature endurance: 3500 hours rated life at 125°C provides measurable long‑term performance in hot operating environments.
• AEC‑Q200 qualification: Enables use in designs that require automotive‑grade component qualification and traceable reliability standards.
• Low‑temperature verified ESR: ESR specified after −40°C testing (190 mΩ at 100 kHz) gives designers validated performance across temperature extremes.
• SMT‑friendly package: Chip‑type SMD can with carrier‑tape compatibility supports automated assembly and consistent board mounting.
• Defined ripple handling: Explicit ripple current specs at 120 Hz and 10 kHz help match the part to power supply and converter requirements.
• Standards‑level leakage control: Leakage current limit of 0.01CV μA (after 2 minutes at 20°C) supports predictable bias behavior in circuits.
