UCZ1V470MCL1GS

The UCZ1V470MCL1GS is a chip-type aluminum electrolytic capacitor engineered for high-reliability power applications. It delivers 47 µF at 35 V in a compact surface-mount can with a wide operating temperature range from −40°C to +125°C, making it suitable for demanding environments that require sustained capacitance, controlled ESR, and long endurance.

Designed for automated assembly, this part combines low-temperature ESR specification, defined ripple-current capability across low and high frequencies, and AEC-Q200 qualification to support robust power filtering and decoupling in industrial and automotive-grade systems.

Key Features

• Capacitance & Voltage — 47 µF capacitance with a rated voltage of 35 V and ±20% tolerance at 120 Hz, 20°C for predictable bulk and decoupling performance.
• Wide Temperature Range — Specified operation from −40°C to +125°C, enabling use in thermally challenging applications.
• High Reliability & Endurance — AEC-Q200 qualified with 3000 hours endurance at 125°C, supporting long-term stability under high-temperature stress.
• Low-Temperature ESR Specification — ESR characterized at −40°C and maintained at 200 mΩ measured at 100 kHz to ensure low-loss behavior across temperature extremes.
• Ripple Current Capability — Low-frequency ripple current of 135 mA (120 Hz) and high-frequency ripple current of 270 mA (10 kHz) for effective smoothing of both line and switching noise.
• Leakage Current — Low leakage current specified at 16.45 µA, useful for energy-sensitive circuits and reducing quiescent loss.
• Surface-Mount, Assembly-Ready — Chip-type radial can SMD in φ8 × 10 L package supplied on embossed carrier taping for automatic mounting machines; recommended land size 8.3 × 8.3 mm.
• Compliance — RoHS compliant, meeting modern environmental requirements.

Typical Applications

• Automotive power modules — AEC-Q200 qualification, wide temperature range, and long endurance support decoupling and bulk smoothing in control modules and power electronics.
• DC–DC converters and switching regulators — Low ESR and defined ripple-current ratings help control output voltage ripple and reduce switching losses across frequency ranges.
• Industrial power supplies — High-temperature endurance and low leakage make this capacitor suitable for elevated-temperature power systems and industrial controllers.
• Backup and hold-up filtering — 47 µF capacitance combined with low leakage provides stable charge storage for short-term hold-up and power integrity tasks.

Unique Advantages

• Temperature-rated reliability: Endurance of 3000 hours at 125°C plus AEC-Q200 qualification for validated long-term performance in hot environments.
• Stable low-temperature performance: ESR specified after −40°C testing and an impedance profile that supports reliable operation across cold starts and low-temperature conditions.
• Balanced ripple handling: Both low- and high-frequency ripple current ratings (135 mA at 120 Hz and 270 mA at 10 kHz) provide versatility across power-stage designs.
• Compact SMD form factor: φ8 × 10 mm can size and SMD mounting enable space-efficient layouts while remaining compatible with automated pick-and-place using embossed carrier tape.
• Low leakage: Specified leakage current of 16.45 µA supports energy-conscious designs and reduces idle power loss.
