UCX1H470MCS1GS

The UCX1H470MCS1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UCX series, specified for high-reliability, surface-mount applications. It delivers 47 µF at 50 V in a compact φ8 × 10 mm can package with embossed carrier taping for automatic placement.

Designed for demanding temperature and vibration environments, this part combines a wide operating temperature range (−40°C to +135°C), AEC-Q200 qualification, and low-temperature ESR specification to support robust power-conversion and high-temperature electronics designs.

Key Features

• Capacitance and Voltage — 47 µF nominal capacitance with ±20% tolerance at 50 V rated voltage suitable for bulk decoupling in compact assemblies.
• High Temperature Endurance — Rated for operation to +135°C with a specified lifetime of 2000 hours at 135°C, supporting prolonged use in elevated-temperature environments.
• Low-Temperature ESR Specification — ESR specified as 250 mΩ at 20°C/100 kHz and additional ESR characterization after −40°C testing, improving performance predictability across temperature extremes.
• Ripple Current Capability — Low-frequency ripple current 135 mA (120 Hz) and high-frequency ripple current 270 mA (10 kHz), enabling reliable handling of AC ripple in power circuits.
• Leakage and Reliability — Low leakage current of 23.5 µA and endurance/shelf-life characteristics defined by JIS/JESD-style test conditions for long-term stability.
• Automotive-Grade and RoHS Compliant — AEC-Q200 rated and RoHS compliant, supporting use in regulated, reliability-focused markets.
• SMD Chip Package and Assembly Ready — φ8 × 10 mm radial can SMD with embossed carrier taping for automatic mounting and vibration-resistant construction.

Typical Applications

• Automotive Systems — AEC-Q200 qualification and −40°C to +135°C temperature range make this capacitor suitable for automotive electronic modules requiring high-reliability bulk capacitance.
• Surface-Mount Power Modules — Compact φ8 × 10 mm SMD can with embossed carrier taping and automatic placement compatibility for space-constrained power assemblies.
• High-Temperature Electronics — Endurance rated for 2000 hours at 135°C and vibration-resistant construction for electronics operating in elevated-temperature environments.

Unique Advantages

• High-temperature endurance: 2000 hours at 135°C provides defined life performance for designs that must operate at elevated temperatures.
• Automotive-grade qualification: AEC-Q200 rating supports selection for reliability-sensitive vehicle electronics.
• Measured low-temperature ESR: ESR characterized with −40°C testing reduces design uncertainty across temperature extremes.
• Assembly-friendly packaging: Embossed carrier taping and SMD can format streamline automated placement and PCB integration.
• Balanced ripple handling: Specified ripple currents at both low and high frequencies help ensure stable performance in switching and linear power stages.
• Compact, vibration-resistant form: Small φ8 × 10 mm footprint with vibration-resistant construction fits tight layouts while addressing mechanical stress concerns.
