UCX1V471MNQ1MS

The UCX1V471MNQ1MS from Nichicon is a chip-type aluminum electrolytic capacitor designed for high-temperature, high-reliability applications. It delivers 470 µF at 35 V in a compact surface-mount radial can package optimized for automated carrier-tape mounting.

Targeted at demanding systems—including automotive electronics—the part combines a wide operating temperature range (−40°C to +135°C), AEC-Q200 qualification, and specified ESR behavior after low-temperature testing to support robust power filtering and energy storage in elevated-temperature environments.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance for bulk energy storage and smoothing in power rails.
• High-Temperature Operation: Rated for operation from −40°C to +135°C with an endurance rating of 2000 hours at 135°C, enabling use in hot environments.
• AEC-Q200 Qualified: Meets AEC-Q200 qualification as noted in product data, supporting use in automotive-grade designs.
• Low‑Temperature ESR Specification: ESR is specified at 70 mΩ measured at 100 kHz and includes ESR behavior after a −40°C test, useful for ensuring performance across the operating temperature range.
• Ripple Current Capacity: Rated ripple current of 375 mA at 120 Hz and 750 mA at 10 kHz for filtering and decoupling in dynamic power applications.
• Surface-Mount, Tape-Fed Friendly: Chip-type radial can SMD package suitable for automatic mounting machines; compact dimensions (L: 1.35 × D: 1.25 cm) and defined land size (1.28 × 1.28 cm).
• Reliability & Shelf Life: Endurance and shelf-life characteristics defined in the datasheet, with specified limits after 2000 hours at 135°C and storage tests consistent with high-reliability usage.
• Environmental Compliance: RoHS compliant in accordance with applicable directives listed in the product data.

Typical Applications

• Automotive power electronics: Bulk smoothing and decoupling in ECUs and power modules where AEC-Q200 qualification and +135°C endurance are required.
• High-temperature industrial controls: Energy storage and filtering for power supplies in environments that reach elevated ambient temperatures.
• Motor drive and inverter control: Decoupling and ripple suppression in drive electronics that demand low ESR and high ripple current capability.
• Sensors and module power rails: Local energy buffering for sensor modules and control boards operating across −40°C to +135°C.

Unique Advantages

• Designed for elevated-temperature service: Rated to +135°C with a 2000-hour endurance specification, the capacitor supports prolonged operation in hot environments.
• AEC-Q200 qualification: Explicit qualification reduces validation overhead for automotive system designers targeting compliant components.
• ESR characterized after low-temperature testing: ESR specification that accounts for −40°C performance helps ensure predictable behavior across thermal extremes.
• Compact, automated-assembly ready: Surface-mount radial can and carrier-tape compatibility streamline PCB assembly for volume production.
• Measurable ripple handling: Defined ripple current ratings at 120 Hz and 10 kHz enable designers to size the component for specific filtering requirements.
