UCZ1H470MCL6GS

The UCZ1H470MCL6GS is a chip-type aluminum electrolytic capacitor designed for high-reliability applications. It delivers 47 µF at 50 V in a compact surface-mount can package with polarization and low-temperature ESR specification.

Engineered for demanding electrical and thermal environments, this capacitor is suited to automotive and other high-temperature electronics that require long endurance at elevated temperatures and verified ESR behavior after low-temperature testing.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, providing bulk decoupling and energy storage in power circuits.
• High-temperature endurance — Rated for operation from -40 °C to +125 °C with an endurance specification of 2000 hours at 125 °C for the φ6.3 × 7.7L case size.
• Low-temperature ESR specification — Includes added ESR specification after the -40 °C test to ensure predictable performance in cold conditions.
• ESR and ripple handling — Equivalent series resistance of 500 mΩ at 100 kHz, with ripple current ratings of 98.5 mA at 120 Hz and 197 mA at 10 kHz for effective filtering across frequencies.
• Surface-mount package — Chip-type radial can SMD, size L: 7.7 × D: 6.3 mm, optimized for automated placement and fed from carrier tape; recommended land size L: 6.6 × W: 6.6 mm.
• Reliability & compliance — AEC‑Q200 qualified and RoHS compliant, supporting use in regulated manufacturing and automotive-grade designs.
• Polarized design — Standard polarized electrolytic construction for use in DC power-supply and energy-storage circuits.

Typical Applications

• Automotive power electronics — Bulk decoupling and smoothing in vehicle power systems where AEC‑Q200 qualification and high-temperature endurance are required.
• DC–DC converters and power management — Output and intermediate stage filtering for regulated supplies operating up to 50 V.
• High-temperature electronics — Power modules and assemblies exposed to extended elevated temperatures, leveraging the 125 °C rating and long endurance at temperature.
