UCD1C471MCL6GS

The UCD1C471MCL6GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount can package designed for high-density PC board assembly. It delivers 470 µF capacitance at a 16 V rating and is tailored for applications requiring compact energy storage with robust ripple handling and wide temperature performance.

Designed for automated assembly and long-term operation, this part is AEC-Q200 qualified, RoHS compliant, and rated for operation from -55°C to +105°C with an endurance rating of 2000 hours at 105°C.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance, providing stable bulk capacitance for decoupling and power smoothing.
• Low Impedance Performance: Rated impedance of 180 mΩ and a tangent of loss angle (tan δ) of 0.16 (measured at 20°C, 120 Hz) to minimize voltage ripple and impedance-related losses.
• High Ripple Current Capability: Low-frequency ripple current 300 mA at 120 Hz and high-frequency ripple current 600 mA at 10 kHz, supporting demanding transient and switching loads.
• Leakage Current: Specified leakage current of 75.2 µA (after 2 minutes at rated voltage, 20°C, as defined by 0.01·C·V rule), enabling predictable static current characteristics.
• Thermal & Reliability Ratings: Operating temperature range from -55°C to +105°C with endurance of 2000 hours at 105°C (for rated voltages in the 6.3–50 V range), ensuring long-term stability under elevated temperature stress.
• Package & Mounting: Chip-type SMD can (φ10 × 7.7L), radial can style for surface mounting on high-density PCBs; supplied in embossed carrier taping compatible with automatic mounting machines.
• AEC-Q200 Qualified & RoHS Compliant: Meets AEC-Q200 qualification and RoHS directive requirements for regulated hazardous substances.

Typical Applications

• Automotive Electronics: Suitable for automotive electronic modules where AEC-Q200 qualification and high-temperature endurance (2000 h at 105°C) are required.
• Power Supply Decoupling: Provides bulk capacitance and ripple suppression on high-density PCBs for DC–DC converters and power regulation circuits.
• Embedded Systems and Control Units: Used for local energy storage and transient smoothing in embedded controllers and power management assemblies.
• Automated Assembly Environments: Supplied in embossed carrier tape to support automated placement on surface-mount production lines.

Unique Advantages

• Low-impedance design: 180 mΩ impedance and specified tan δ deliver reduced ripple and improved voltage stability under dynamic loads.
• High ripple tolerance across frequencies: Distinct low-frequency and high-frequency ripple ratings (300 mA @120 Hz, 600 mA @10 kHz) address both power-line and switching noise demands.
• Automotive-capable reliability: AEC-Q200 qualification and 2000-hour endurance at 105°C support deployment in automotive-grade assemblies.
• Compact SMD form factor: φ10 × 7.7L chip-type can enables dense PCB layouts while maintaining significant capacitance.
• Manufacturing-ready packaging: Embossed carrier taping facilitates high-throughput automatic placement and reduces assembly handling time.
• Regulatory compliance: RoHS-compliant construction simplifies environmental qualification for regulated markets.
