UCM1A471MCS1GS

The UCM1A471MCS1GS is a chip-type, low-impedance surface-mount aluminum electrolytic capacitor from Nichicon’s UCM series. It delivers 470 µF of capacitance at a 10 V rating in a compact φ6.3 × 7.7 mm can suitable for automated PCB assembly.

Engineered for demanding environments, this part supports automotive applications with AEC-Q200 qualification, a wide operating temperature range (−55 °C to 105 °C), and lifecycle performance specified at elevated temperature.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 10 V rated voltage and a tolerance of −20% to +20% for bulk energy storage in compact SMD footprints.
• Low Impedance — Chip-type, low-impedance construction designed to reduce effective series resistance for improved AC performance; tanδ (DF) of 0.19 measured at 20 °C, 120 Hz.
• Ripple Current Handling — 300 mA at 120 Hz (low frequency) and 600 mA at 10 kHz (high frequency) to support power-supply decoupling and transient current demands.
• Leakage Current — Low leakage current of 47 µA, measured per product test conditions after rated voltage application.
• High Temperature Endurance — Rated for operation from −55 °C to 105 °C with an endurance life of 2000 hours at 105 °C.
• Compact SMD Package — φ6.3 × 7.7 mm can (surface-mount) with recommended land pattern L: 6.6 mm × W: 6.6 mm, supplied in embossed carrier tape for pick-and-place assembly.
• AEC-Q200 Qualified — Meets AEC-Q200 requirements for use in automotive electronics (reference product data).
• RoHS Compliant — Conforms to RoHS environmental requirements.

Typical Applications

• Automotive electronic control modules — AEC-Q200 qualification and a −55 °C to 105 °C operating range make this capacitor suitable for power rail support in automotive control units where temperature and endurance are critical.
• Power supply filtering in vehicle systems — 470 µF capacitance combined with high ripple-current capability (300 mA @120 Hz, 600 mA @10 kHz) supports smoothing and transient handling on low-voltage rails.
• Board-level SMD assemblies — Compact φ6.3 × 7.7 mm can and embossed carrier tape packaging enable automated placement in high-density surface-mount layouts.

Unique Advantages

• High energy density in a compact SMD can — 470 µF in a φ6.3 × 7.7 mm package reduces board area compared with larger can styles while keeping bulk capacitance.
• Designed for elevated-temperature endurance — 2000 hours at 105 °C provides a quantified lifetime metric for designs exposed to sustained high temperatures.
• Measured AC performance — Specified tanδ (0.19 at 20 °C, 120 Hz) and defined ripple-current ratings help predict behavior under AC loading conditions.
• Automotive-ready qualification — AEC-Q200 rating and RoHS compliance simplify selection for automotive electronics projects requiring qualified components.
• Pick-and-place friendly packaging — Embossed carrier tape supply streamlines high-volume automated assembly and inspection.
