UCX1H471MNJ1MS

The UCX1H471MNJ1MS from Nichicon is a chip‑type aluminum electrolytic capacitor in the UCX series, engineered for continuous operation in elevated temperature environments up to +135°C. Designed as a surface‑mount radial can compatible with carrier‑tape automated assembly, it targets applications that require high capacitance, defined ESR behavior across temperature, and AEC‑Q200 qualification.

With a rated capacitance of 470 µF at 50 V and polarized construction, this part delivers bulk energy storage, smoothing, and decoupling in compact power and control modules where thermal endurance and qualification matter.

Key Features

• Core Electricals — 470 µF nominal capacitance at 50 V with ±20% tolerance; polarized aluminum electrolytic construction for bulk energy storage and smoothing.
• High‑Temperature Performance — Rated for operation from −40°C to +135°C with endurance specified as 2000 hours at 135°C under rated voltage.
• ESR and Low‑Temperature Specification — Equivalent series resistance specified at 70 mΩ (measured at 100 kHz); ESR specification is retained after low‑temperature (−40°C) testing.
• Ripple Handling — Ripple current ratings of 500 mA at 120 Hz and 1 A at 10 kHz for power filtering and decoupling duties across frequency ranges.
• Package and Assembly — Chip‑type radial can in an SMD format for surface mounting; compatible with automatic mounting machines fed by carrier tape; recommended land size: 1.63 × 1.63 cm.
• Qualification and Compliance — AEC‑Q200 qualified and RoHS compliant, supporting designs that require regulated component qualifications.

Typical Applications

• Automotive control modules — Bulk filtering and energy storage in electronic control units and power modules exposed to elevated under‑hood temperatures.
• Power conversion and DC‑DC converters — Output smoothing and transient buffering where high capacitance and defined ESR at frequency are needed.
• High‑temperature industrial electronics — Decoupling and energy storage in instrumentation and power assemblies that operate reliably up to +135°C.

Unique Advantages

• High‑temperature endurance: Specified 2000 hours at 135°C under rated voltage provides a measured reliability baseline for elevated‑temperature designs.
• Cold‑temperature ESR stability: ESR characterization including post‑test performance at −40°C and a measured 70 mΩ at 100 kHz help predict behavior across the operating range.
• AEC‑Q200 qualification: Enables use in applications requiring automotive‑grade component qualification and traceable reliability data.
• SMD chip format for automated assembly: Carrier‑tape compatibility and a compact radial can package simplify placement in high‑volume production lines.
• Compact, high capacitance footprint: 470 µF in a package with dimensions L: 1.65 × D: 1.6 cm provides substantial bulk capacitance in a small board area.
• Regulatory compliance: RoHS conformity supports designs targeting regulated markets and environmental compliance.
