UCD1V471MNQ1MS

The UCD1V471MNQ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount applications. It provides 470 µF capacitance at a rated voltage of 35 V in a compact SMD can package (φ12.5 × 13.5 mm).

Built for high-density PCB assembly and automatic mounting (embossed carrier tape), this component targets automotive and other demanding electronics where long endurance, wide temperature range, and elevated ripple-current capability are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 35 V operation.
• Low Loss / Low Impedance — Tangent of loss angle (tan δ) specified at 0.12 (measurement condition: 20°C, 120 Hz), supporting reduced dissipation in AC conditions.
• Ripple Current Capability — Low-frequency ripple current of 550 mA at 120 Hz and high-frequency ripple current of 1.1 A at 10 kHz to support power-conditioning and decoupling needs.
• Leakage Current — Specified leakage current of 164.5 µA, measured after rated voltage application.
• Robust Temperature & Endurance — Rated operation from −55°C to 105°C with an endurance life of 5000 hours at 105°C.
• Automotive-Grade Qualification — AEC-Q200 qualified, suitable for automotive electronic system requirements.
• SMD Packaging & Assembly — Chip-type radial can SMD (φ12.5 × 13.5 mm) supplied in embossed carrier taping for automated placement; recommended land size L: 12.8 mm × W: 12.8 mm.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and wide temperature range make the capacitor suitable for electronic control modules and other automotive sub-systems requiring reliable SMD filtering and energy storage.
• High-density Surface-mount Assemblies — Chip-type can package and embossed carrier tape packaging enable automated placement on compact, high-density PCBs.
• Power Management Modules — High ripple-current ratings and low tan δ support use in power-conditioning stages where ripple handling and stable performance over temperature are important.

Unique Advantages

• High Capacitance in a Compact SMD Can — 470 µF in a φ12.5 × 13.5 mm package delivers bulk energy storage without large through-hole components.
• Designed for Automated Assembly — Supplied in embossed carrier tape for pick-and-place compatibility, simplifying production on automated lines.
• Long Endurance at Elevated Temperature — 5000 hours at 105°C provides predictable lifetime behavior for long-term deployments.
• Automotive-Grade Qualification — AEC-Q200 status supports use in automotive designs that require passives qualified to industry stress tests.
• Wide Operating Temperature — −55°C to 105°C operation covers a broad range of environmental conditions encountered in vehicle and industrial electronics.
• Measurable Ripple and Leakage Performance — Specified low- and high-frequency ripple current ratings and defined leakage current enable engineers to size and validate power designs precisely.
