UCZ1H330MCS1GS

The UCZ1H330MCS1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UCZ series designed for high-temperature, high-reliability applications. It is a surface-mount, polarized capacitor specified for operation from -40 °C to +125 °C and intended for automated assembly (carrier-tape feed).

Targeted use cases include automotive and other demanding markets that require AEC-Q200 qualification, RoHS compliance, and verified performance across wide temperature ranges. The part delivers predictable ESR and ripple-handling characteristics together with a long high-temperature lifetime.

Key Features

• Electrical rating: 33 µF capacitance at 50 V rated voltage with ±20% tolerance, suitable for decoupling and bulk energy storage in power subsystems.
• High-temperature capability: Rated operating temperature range −40 °C to +125 °C with a specified lifetime of 3000 hours at 125 °C.
• Low-temperature ESR specification: Equivalent series resistance specified as 250 mΩ at 100 kHz; datasheet includes ESR specification after the −40 °C test for verified low-temperature performance.
• Ripple current performance: 135 mA at 120 Hz and 270 mA at 10 kHz, allowing predictable ripple handling across common frequencies.
• Surface-mount can package: Radial, can-style SMD package designed for automatic mounting machines fed with carrier tape; recommended PCB land size 8.3 × 8.3 mm.
• Quality & compliance: AEC-Q200 qualified and RoHS compliant, reflecting suitability for regulated, high-reliability applications.

Typical Applications

• Automotive control modules: Bulk and decoupling capacitance for ECUs and power modules where AEC-Q200 qualification and high-temperature operation are required.
• Power supplies and DC–DC converters: Bulk energy storage and ripple suppression in compact, surface-mount power designs operating up to +125 °C.
• Industrial electronics: High-temperature industrial controllers and sensor interfaces that require reliable SMD capacitors with defined ESR across temperature extremes.
• Automated assembly environments: Designed for carrier-tape feeding and pick-and-place assembly on high-volume SMD production lines.

Unique Advantages

• High-temperature endurance: 3000 hours specified at 125 °C provides a defined lifetime metric for thermal-stress designs.
• Temperature-verified ESR: ESR specified at 100 kHz (250 mΩ) and documented after −40 °C testing, supporting designs that span wide temperature ranges.
• AEC-Q200 qualification: Formal qualification for demanding markets enables use in applications that require automotive-grade component qualification.
• SMD can form factor for automated production: Carrier-tape compatible packaging and a defined PCB land size (8.3 × 8.3 mm) simplify integration into assembly workflows.
• Measured ripple capacity: Dual-frequency ripple ratings (120 Hz and 10 kHz) give designers clear expectations for ripple handling in power applications.
• Regulatory compliance: RoHS directive compliance supports regulatory and environmental requirements.
