UCX1V471MNJ1MS

The UCX1V471MNJ1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation and automated surface-mount assembly. It delivers 470 µF at 35 V in a compact SMD can package and is targeted at applications requiring wide temperature range operation and automotive-grade reliability.

Key value comes from an extended operating range of −40 °C to +135 °C, AEC‑Q200 qualification, and endurance validated to 2000 hours at 135 °C, making it suitable for harsh environments and high-reliability systems.

Key Features

• Electrical Capacity — 470 µF rated capacitance with ±20% tolerance at 120 Hz, 20 °C provides bulk energy storage in a compact SMD form.
• Voltage Rating — 35 V rated voltage suitable for many mid-voltage power rails and DC‑DC converter outputs.
• Low‑temperature ESR Spec — ESR specified after test at −40 °C, with an equivalent series resistance of 70 mΩ measured at 100 kHz, supporting stable performance across temperature extremes.
• High‑temperature Endurance — Qualified to withstand 2000 hours at 135 °C with defined limits for capacitance change, tan δ, and leakage current.
• Ripple Current Capability — Rated ripple currents of 375 mA at 120 Hz and 750 mA at 10 kHz support filtering and decoupling in power applications.
• Surface‑mount Can Package — Chip‑type SMD (radial can) designed for automatic mounting with carrier tape, enabling high-volume PCB assembly.
• Quality and Compliance — AEC‑Q200 qualified and RoHS compliant for regulated and automotive applications.

Typical Applications

• Automotive systems — Bulk filtering and smoothing in electronic control modules where AEC‑Q200 qualification and operation to +135 °C are required.
• High‑temperature electronics — Power reservoirs and decoupling in systems that operate continuously at elevated temperatures up to +135 °C.
• Automated surface‑mount production — Chip‑type SMD design compatible with carrier‑tape automated pick-and-place assembly for efficient manufacturing.
• Power supply filtering — 470 µF capacitance, 35 V rating, and specified ESR make it suitable for smoothing outputs of DC‑DC converters and power regulators.

Unique Advantages

• Automotive‑grade reliability: AEC‑Q200 qualification and defined endurance at 135 °C provide confidence for vehicle electronics and other mission‑critical systems.
• Wide operating temperature: Guaranteed performance from −40 °C to +135 °C addresses designs exposed to extreme thermal conditions.
• Tuned ESR at low temperature: ESR specified after −40 °C testing and a 70 mΩ equivalent at 100 kHz help ensure predictable high‑frequency behavior in cold environments.
• High endurance: 2000 hours at 135 °C demonstrates long‑term stability for prolonged high‑temperature service.
• SMD compatibility for automated assembly: Chip package and carrier‑tape feed compatibility reduce assembly complexity and support volume manufacturing.
• Measured ripple handling: Specified ripple current ratings at 120 Hz and 10 kHz enable selection based on application frequency content and thermal management.
