UCX1V471MNS1MS

The UCX1V471MNS1MS is a chip-type aluminum electrolytic capacitor engineered for high-temperature, high-reliability applications. With a 470 µF capacitance at 35 V and an operating range from -40 °C to +135 °C, it targets demanding environments where long endurance and stable ESR are required.

Designed for surface-mount assembly and carrier-tape feeding, this AEC-Q200 qualified, RoHS-compliant part delivers predictable ripple handling and long-term performance for automotive and industrial power electronics.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a rated voltage of 35 V with ±20% tolerance, suitable for bulk decoupling and energy storage on power rails.
• High Temperature Operation — Rated for operation from -40 °C to +135 °C, enabling use in elevated-temperature zones and harsh environments.
• Low ESR Specified — 70 mΩ equivalent series resistance measured at 100 kHz, with ESR behavior specified after low-temperature (-40 °C) testing for reliable AC performance.
• Endurance — Qualified for 2000 hours at 135 °C with specifications for capacitance change, loss tangent and leakage current after the endurance test.
• Ripple Current Capability — 375 mA at 120 Hz and 750 mA at 10 kHz, supporting both low- and high-frequency ripple suppression in power circuits.
• Surface-Mount, Assembly-Friendly — Chip-type SMD radial/can package intended for automatic mounting machines fed with carrier tape; recommended PCB land size L:1.28 × W:1.28 cm.
• Compliance & Qualification — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting designs that require recognized reliability standards.

Typical Applications

• Automotive power electronics — Bulk decoupling and smoothing on power rails in electronic control modules and power distribution units operating in high-temperature compartments.
• DC–DC converters — Output filtering and energy buffering where low ESR and high ripple handling at elevated temperature improve regulator stability and efficiency.
• Industrial controls — Power supply and drive electronics exposed to wide ambient temperature ranges and demanding duty cycles.

Unique Advantages

• High-temperature endurance: Rated for 2000 hours at 135 °C, providing predictable lifetime behavior in elevated-temperature applications.
• Specified low-temperature ESR performance: ESR is characterized after -40 °C testing, giving designers visibility into AC behavior across the operating range.
• Dual-frequency ripple support: Clear ripple current ratings at both 120 Hz and 10 kHz enable selection for mixed-frequency power systems.
• Assembly-ready SMD form factor: Carrier-tape compatibility and defined PCB land size simplify automated placement and assembly processes.
• Automotive-grade qualification: AEC-Q200 qualification supports deployment in safety- and reliability-focused vehicular electronics.
• Regulatory compliance: RoHS conformity for designs targeting markets with restricted substance requirements.
