UCZ1H471MNQ1MS

The UCZ1H471MNQ1MS is a 470 µF, 50 V aluminum electrolytic chip capacitor from Nichicon’s UCZ series, designed for high-reliability surface-mount applications. It combines high-capacitance density in a chip-style SMD can with specifications targeted for sustained operation at elevated temperatures.

Key market segments include automotive and other high-temperature electronic systems where AEC-Q200 qualification, a wide operating temperature range, and long endurance at +125°C are required.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 50 V, with ±20% tolerance, providing substantial bulk energy storage in a compact SMD package.
• High Temperature Operation — Rated for continuous operation from −40°C to +125°C, supporting designs exposed to elevated ambient temperatures.
• AEC‑Q200 Qualified — Series-level AEC‑Q200 qualification for applications requiring automotive-grade reliability.
• Low‑Temperature ESR Specification — Includes added ESR specification following the −40°C test, plus a stated ESR of 80 mΩ at 100 kHz for predictable performance across temperature extremes.
• Designed for Long Endurance — Endurance specified at 3500 hours at 125°C for the corresponding case size, supporting long-term operation in demanding environments.
• Ripple Current Capability — Rated ripple current of 1 A at 120 Hz and 2 A at 10 kHz to handle AC loading and switching noise in power rails.
• Surface‑Mount, Carrier‑Tape Compatible — Chip-type SMD can package suitable for automated placement with carrier tape to support high-volume assembly.
• RoHS Compliant — Conforms to RoHS directive requirements for lead‑free designs.
• Soldering Heat Resistance — Meets datasheet resistance-to-soldering-heat requirements (hot plate at 250°C for 30 seconds) while retaining specified electrical characteristics after recovery to 20°C.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and a −40°C to +125°C operating range make this capacitor suitable for vehicle power systems and electronic control modules that require robust bulk capacitance.
• High‑Temperature Power Modules — 470 µF at 50 V with specified ripple current and low-temperature ESR behavior supports bulk smoothing and decoupling inside power assemblies operating at elevated temperatures.
• Surface‑Mount Production Lines — Chip-style SMD can packaged for carrier-tape feeding and automated placement, simplifying integration into high-volume manufacturing flows.

Unique Advantages

• Automotive‑Grade Reliability: AEC‑Q200 qualification and extended endurance at 125°C provide traceable reliability for vehicle electronics and other demanding systems.
• Wide Thermal Headroom: −40°C to +125°C rating ensures stable performance across extreme ambient conditions encountered in automotive and industrial environments.
• Predictable ESR Across Temperature: The added ESR specification after −40°C testing and the 80 mΩ (100 kHz) ESR rating enable designers to model frequency-dependent losses more accurately.
• High Bulk Capacity in SMD Form: 470 µF in a compact chip can reduces the need for larger through-hole parts while supporting compact board layouts.
• Robust AC Handling: Specified ripple current at both low and high frequencies (1 A @120 Hz, 2 A @10 kHz) helps manage switching and ripple currents in power conversion stages.
• Manufacturing‑Friendly: Carrier‑tape compatibility and soldering-heat resistance streamline assembly and reflow processes without compromising performance.
