UCZ1J471MNQ1MS

The UCZ1J471MNQ1MS is a chip‑type aluminum electrolytic capacitor engineered for high‑reliability applications that require operation in elevated ambient temperatures. It combines a 470 µF capacitance and 63 V rated voltage with a chip can SMD package suitable for automated placement.

Designed for applications that demand long endurance and stable performance across a wide temperature range, this capacitor targets automotive and other high‑temperature electronic systems where AEC‑Q200 qualification, low temperature ESR behavior and extended life at 125°C are important.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 63 V, with a tolerance of ±20% (measured at 120 Hz, 20°C).
• High Temperature Operation — Specified operating temperature range from −40°C to +125°C to support demanding thermal environments.
• Low‑temperature ESR Specification — Low temperature ESR characterization and added ESR measurement after −40°C testing; specified ESR: 110 mΩ at 100 kHz.
• Long Endurance — Rated for 3,500 hours at 125°C (endurance condition noted for this case size), with allowable capacitance change and leakage current limits defined in the endurance specification.
• Ripple Current Ratings — 1 A at 120 Hz and 2 A at 10 kHz, enabling use in applications with moderate AC/ripple stress.
• Surface‑mount, Tape‑Feed Compatible — Chip can SMD package designed for automatic mounting machines fed with carrier tape; surface mount land size: 1.83 × 1.83 cm.
• Leakage Current — After 2 minutes’ application of rated voltage at 20°C, leakage current is specified as not more than 0.01CV (µA), per datasheet measurement conditions.
• Compliance & Qualification — AEC‑Q200 qualified and RoHS compliant (2011/65/EU,(EU)2015/863), supporting regulated and automotive design requirements.
• Package Dimensions — Component size L: 1.65 cm × D: 1.8 cm, suitable for compact PCB layouts where a chip can SMD is required.
• Polarized — Polarized electrolytic construction for use where polarity is defined in the circuit.

Typical Applications

• Automotive Electronics — Suited to electronic control units and power systems that require components qualified to AEC‑Q200 and stable operation to +125°C.
• High‑Temperature Electronic Systems — Designed for power and control assemblies exposed to elevated ambient temperatures where endurance at 125°C is required.
• Automated Surface‑Mount Assemblies — Chip can SMD format and carrier‑tape compatibility enable efficient placement in automated production lines.

Unique Advantages

• High‑temperature endurance: Rated endurance of 3,500 hours at 125°C for sustained performance in hot operating environments.
• AEC‑Q200 qualification: Provides a documented qualification path for automotive and other reliability‑focused applications.
