UCZ1H470MCS1GS

The UCZ1H470MCS1GS is a chip-type aluminum electrolytic capacitor designed for high-reliability applications. It provides 47 µF capacitance at 50 V in a compact surface-mount package and is optimized for elevated operating temperatures up to +125°C.

Targeted at demanding markets such as automotive electronics, this part combines low-temperature ESR performance, added ESR specification after -40°C testing, AEC‑Q200 qualification, and RoHS compliance to support robust power filtering and decoupling in temperature-critical designs.

Key Features

• Capacitance & Voltage: 47 µF rated capacitance at 50 V for bulk decoupling and energy storage in power rails.
• High‑Temperature Operation: Specified for −40 °C to +125 °C operation and endurance of 3000 hours at 125 °C for sustained high-temperature reliability.
• Low‑Temperature ESR Specification: ESR specified after test at −40 °C and typical ESR of 250 mΩ measured at 100 kHz, supporting stable performance across temperature extremes.
• Ripple Current Capability: Rated ripple current of 135 mA at 120 Hz and 270 mA at 10 kHz to handle both low- and high-frequency ripple components.
• Automotive Qualification & Environmental Compliance: AEC‑Q200 qualified and RoHS compliant to meet industry reliability and environmental requirements.
• Surface-Mount Package: Chip-type, radial can SMD package suitable for automatic mounting with carrier tape; recommended land size L 8.3 mm × W 8.3 mm.
• Design Parameters: Polarized device with ±20% capacitance tolerance and physical size approximately L: 1 cm × D: 0.8 cm for compact board placement.

Typical Applications

• Automotive electronics: Power supply filtering and decoupling in modules that require AEC‑Q200 qualification and +125 °C operation.
• Engine control and power modules: Energy storage and ripple suppression where sustained high-temperature endurance and low-temperature ESR are required.
• Industrial power systems: Bulk decoupling in temperature-challenging environments that demand long endurance at elevated temperatures.

Unique Advantages

• High-temperature endurance: 3000 hours at 125 °C gives designers predictable life performance in hot environments.
• Temperature-stable ESR: ESR characterization after −40 °C testing plus a measured 250 mΩ at 100 kHz helps maintain stability across thermal extremes.
• Automotive-ready qualification: AEC‑Q200 qualification provides a documented reliability baseline for automotive and similarly demanding applications.
• Surface-mount assembly compatible: Chip-type design and carrier-tape mounting support automated placement to streamline manufacturing.
• RoHS compliant: Meets environmental directive requirements for lead-free designs.
