UCZ1H102MNJ1MS

The UCZ1H102MNJ1MS is a Nichicon UCZ-series aluminum electrolytic chip capacitor designed for high-reliability, surface-mount applications. It is a chip-type polarized capacitor rated at 1 mF and 50 V with a broad operating temperature range from −40°C to +125°C.

Engineered for demanding environments, this part offers low-temperature ESR characterization, an added ESR specification after −40°C testing, AEC-Q200 qualification, and RoHS compliance—features that address reliability and qualification requirements in automotive and other harsh-environment designs.

Key Features

• Capacitance & Voltage — 1 mF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for bulk energy storage and decoupling in power subsystems.
• Wide Temperature Range — Specified to operate from −40°C to +125°C, enabling use in high-temperature environments.
• High-Temperature Endurance — Rated lifetime of 4000 hours at 125°C, supporting long-term stability under elevated temperatures.
• Low-Temperature ESR Performance — Low temperature ESR specification with a defined ESR after −40°C testing; typical ESR value is 40 mΩ measured at 100 kHz.
• Ripple Current Capability — Specified ripple handling of 1.4 A at 120 Hz and 2.8 A at 10 kHz for AC stress management in power applications.
• Surface-Mount, Tape-Fed Packaging — Chip-type radial can SMD package designed for automatic mounting machines fed with carrier tape, easing PCB assembly.
• Industry Qualification & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting use where documented qualification and environmental compliance are required.
• Compact Size — Physical dimensions L: 2.15 cm × D: 1.6 cm with recommended land size L: 1.63 cm × W: 1.63 cm to assist PCB layout.

Typical Applications

• Automotive Power Modules — AEC-Q200 qualification and −40°C to +125°C rating make this capacitor suitable for power filtering and bulk storage in automotive ECUs and power electronics.
• DC–DC Converters — 1 mF capacitance, low ESR and specified ripple current ratings support smoothing and decoupling in converter output stages.
• Industrial Controls — High-temperature endurance and long lifetime at 125°C enable reliable energy storage in industrial power supplies and control modules operating in elevated ambient conditions.
• Backup Power & Hold-Up Circuits — Compact surface-mount can package provides energy reservoir capability where space is constrained and robust performance is required.

Unique Advantages

• Designed for High-Temperature Operation: Specified operation up to +125°C and a 4000 h lifetime at that temperature provide clear, verifiable endurance for hot environments.
• Qualification-Grade Reliability: AEC-Q200 qualification supports use in designs that require recognized component-level automotive qualification.
• Low-Temperature ESR Assurance: An added ESR specification after −40°C testing plus a 40 mΩ ESR (100 kHz) measurement helps designers predict performance across the full temperature range.
• Assembly-Ready Package: Tape-fed, surface-mount radial can format simplifies automated placement and reduces PCB assembly complexity.
• Measured Ripple Performance: Specified ripple currents at both 120 Hz and 10 kHz allow designers to size the capacitor confidently for AC stress conditions.
