UCZ1A331MCS6GS

The UCZ1A331MCS6GS is a chip-type aluminum electrolytic capacitor designed for surface-mount applications that require sustained performance at elevated temperatures. It offers 330 µF capacitance at 10 V in a compact, tape-fed SMD can package and is RoHS compliant and AEC-Q200 qualified for demanding environments.

With an operating range from −40°C to +125°C, specified low-temperature ESR behavior and a 3000-hour endurance at 125°C, this capacitor is targeted at electronic systems that need verified high-temperature stability and predictable electrical behavior across frequency and temperature extremes.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance for bulk storage and decoupling in low-voltage power rails.
• High-temperature rating — Rated for operation from −40°C to +125°C with endurance specified at 3000 hours at 125°C.
• Low-temperature ESR specification — ESR defined at low temperature with an indicated 200 mΩ at 100 kHz; ESR is also specified after the −40°C test to ensure performance in cold starts.
• Ripple current performance — Rated ripple current of 135 mA at 120 Hz and 270 mA at 10 kHz for AC and switching applications.
• Surface-mount, tape-fed package — Chip/Can SMD (radial can footprint) designed for automatic mounting machines supplied by carrier tape; recommended PCB land size L: 8.3 × W: 8.3 mm.
• Reliability and compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact form factor — Small package dimensions (L: 1 × D: 0.8 cm) suitable for space-constrained board layouts.

Typical Applications

• Automotive electronics — Bulk smoothing and decoupling in control modules and power distribution where AEC-Q200 qualification and +125°C operation are required.
• Power management for high-temperature systems — Energy storage and ripple suppression in DC–DC converters and power rails exposed to elevated ambient temperatures.
• Industrial control equipment — Capacitor for power filtering in sensors, drives, and embedded controllers operating across −40°C to +125°C.
• Compact SMD designs — Board-level decoupling where a tape-fed, surface-mount can capacitor provides required capacitance in limited PCB area.

Unique Advantages

• Designed for +125°C operation: Endurance specified at 3000 hours at 125°C provides a quantified measure of long-term high-temperature performance.
• Low-temperature verified ESR: ESR characterized at 100 kHz (200 mΩ) and after −40°C testing, enabling predictable cold-start and high-frequency behavior.
• AEC-Q200 qualified: Qualification to AEC-Q200 supports use in regulated automotive and similarly demanding electronic designs.
• Tape-fed surface-mount format: Compatible with automated assembly for efficient production and consistent placement in high-volume manufacturing.
• High ripple handling: Specified ripple currents at both 120 Hz and 10 kHz (135 mA and 270 mA respectively) to support AC and switching power applications.
• RoHS compliant: Meets RoHS directive requirements for environmental compliance in commercial and industrial products.
