UCZ1H330MCS6GS

The UCZ1H330MCS6GS is a chip-type aluminum electrolytic capacitor designed for high-reliability applications. It delivers 33 µF capacitance at a 50 V rating in a compact surface-mount can package suitable for automated carrier-tape pick-and-place assembly.

Engineered for demanding thermal environments, this part supports an operating range from -40 °C to +125 °C, includes low-temperature ESR specification and AEC-Q200 qualification, making it appropriate for electronics that require extended high-temperature endurance and stable performance across wide temperatures.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance with a 50 V working voltage and ±20% tolerance, suitable for decoupling and bulk storage in compact PCBs.
• Temperature Range — Specified operation from -40 °C to +125 °C to support designs exposed to wide ambient and board-level temperatures.
• Low-temperature ESR — Added ESR specification after the -40 °C test to ensure predictable equivalent series resistance under cold conditions; measured ESR is 500 mΩ at 100 kHz.
• High-temperature endurance — Rated for 2000 hours at 125 °C, with endurance criteria defined for capacitance change and leakage current after the stress period.
• Ripple current capability — Rated ripple current values of 98.5 mA at 120 Hz and 197 mA at 10 kHz for AC load considerations at specified frequencies.
• Surface-mount, tape-fed can package — Chip-type radial can in an SMD package designed for automatic mounting machines; PCB land recommendation L: 6.6 × W: 6.6 mm supports straightforward layout.
• Reliability & compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and reliability-focused designs.
• Mechanical footprint — Compact size L: 7.7 × D: 6.3 mm for space-constrained board designs.

Typical Applications

• Automotive electronics — Suited for control modules and systems where operation from -40 °C to +125 °C and AEC-Q200 qualification are required.
• Power-supply smoothing — Provides bulk capacitance and ripple filtering on 50 V rails where 33 µF and specified ripple currents meet system needs.
• Harsh-environment embedded systems — Useful in electronics that demand stable ESR and capacitance through wide temperature swings and extended high-temperature exposure.

Unique Advantages

• High-temperature endurance: 2000 hours at 125 °C ensures sustained capacitance and leakage performance for prolonged elevated-temperature operation.
• Predictable low-temperature behavior: Added ESR specification after -40 °C testing provides designers with verifiable ESR performance in cold conditions.
• Compact SMD can: Small L: 7.7 × D: 6.3 mm footprint and tape-feed compatibility simplify board layout and automated assembly for high-volume production.
• Application-grade qualification: AEC-Q200 qualification and RoHS compliance support use in regulated and reliability-focused product lines.
• Frequency-aware ripple specs: Published ripple currents at 120 Hz and 10 kHz allow designers to evaluate thermal and AC stress for both low- and high-frequency applications.
