UCZ1H101MCL1GS

The UCZ1H101MCL1GS is a surface-mount aluminum electrolytic capacitor in the Nichicon UCZ series, offering 100 µF capacitance at a 50 V rating in a compact φ10 × 10 mm can. Engineered for demanding temperature and vibration environments, it delivers low ESR and controlled loss characteristics for reliable power conditioning in compact electronic assemblies.

Designed for automated board assembly, this part supports embossed carrier taping and is qualified to AEC-Q200. Key electrical characteristics include a tanδ of 0.16 (20°C, 120 Hz), ESR of 200 mΩ (20°C, 100 kHz), and rated ripple currents suitable for both low- and high-frequency applications.

Key Features

• Core Electricals: 100 µF capacitance with a ±20% tolerance and 50 V rated voltage — suitable where mid-voltage energy storage and smoothing are required.
• Low-Loss Performance: tanδ = 0.16 measured at 20°C/120 Hz, providing predictable dissipation behavior for AC and ripple handling.
• Low ESR at High Frequency: ESR = 200 mΩ at 20°C/100 kHz, enabling effective high-frequency ripple attenuation in compact power stages.
• Ripple Current Capability: Rated for 250 mA at 120 Hz (low frequency) and 500 mA at 10 kHz (high frequency), supporting both bulk smoothing and higher-frequency switching environments.
• Extended Temperature & Endurance: Operating range of −40°C to +125°C with a rated endurance of 3000 hours at 125°C for the φ10 case size, suited to elevated-temperature system locations.
• Assembly & Packaging: Surface-mount can construction (φ10 × 10L) optimized for automatic placement and supplied in embossed carrier taping for high-throughput assembly.
• Reliability & Compliance: Polarized aluminum electrolytic design, AEC-Q200 qualified and RoHS compliant, supporting regulated industry requirements.
• Leakage Current: Specified leakage current of 50 µA, enabling stable bias performance after voltage application.

Typical Applications

• Automotive Electronics: Engine control modules, body electronics and auxiliary power circuits where AEC-Q200 qualification and high-temperature endurance (−40°C to +125°C) are required.
• Power Management Modules: Local energy storage and bulk smoothing in compact DC–DC converters and regulator boards that demand low ESR and high ripple-current capability.
• Industrial Controls: Power filtering and decoupling in motor drives and control units exposed to elevated ambient temperatures and continuous operation.

Unique Advantages

• Compact, serviceable form factor: φ10 × 10 mm SMD can provides substantial capacitance in a small footprint for space-constrained designs.
• High-temperature endurance: 3000 hours at 125°C ensures long-term stability in hot operating environments, reducing maintenance and replacement frequency.
• Balanced low- and high-frequency performance: Combined low tanδ and low ESR at 100 kHz deliver effective attenuation across a wide ripple spectrum.
• Assembly-ready packaging: Supplied in embossed carrier tape for reliable pick-and-place compatibility in automated manufacturing.
• Industry-grade qualification: AEC-Q200 qualification and RoHS compliance provide traceable suitability for regulated applications.
