UCD1A331MCL6GS

The UCD1A331MCL6GS is a surface-mount aluminum electrolytic capacitor from Nichicon's UCD series, engineered for low impedance and high-density PCB assemblies. It delivers 330 µF capacitance at a 10 V rating in a compact φ10 × 7.7 mm SMD can and is supplied in embossed carrier taping for automated placement.

Designed for demanding operating environments, this part supports a wide temperature range (−55 °C to 105 °C), AEC-Q200 qualification, and a 2000-hour endurance at 105 °C, making it suitable for applications that require robust thermal and lifecycle performance.

Key Features

• Capacitance and Voltage — 330 µF capacitance at a 10 V rated voltage for bulk energy storage and decoupling in low-voltage power rails.
• Low Impedance Performance — Specified impedance of 180 mΩ and tan δ of 0.19 (measured at 20 °C, 120 Hz), supporting stable AC performance and reduced ripple under load.
• High Ripple Handling — Low-frequency ripple current of 300 mA (120 Hz) and high-frequency ripple current of 600 mA (10 kHz) for effective smoothing in both slow and fast switching environments.
• Leakage and Reliability — Low leakage current rated at 33 µA and endurance of 2000 hours at 105 °C, providing predictable long-term behavior after high-temperature stress.
• Thermal Range & Qualification — Wide operating temperature from −55 °C to 105 °C and AEC-Q200 qualification for use in regulated and high-temperature applications.
• Compact SMD Can — φ10 × 7.7 mm package (radial, can - SMD) optimized for high-density PCB layouts; surfaced for automated assembly via embossed carrier taping.
• RoHS Compliant — Meets RoHS requirements for environmental compliance.

Typical Applications

• Automotive electronic modules — Suitable for automotive systems where AEC-Q200 qualification, wide temperature range, and endurance at 105 °C are required.
• Power supply smoothing — Bulk decoupling and smoothing on low-voltage power rails that require 330 µF at 10 V and strong ripple-current capability.
• High-density SMD assemblies — Compact φ10 × 7.7 mm can and embossed carrier taping make this capacitor suitable for automated placement on densely populated PCBs.

Unique Advantages

• AEC-Q200 qualified: Provides the confidence needed for regulated automotive-grade designs that demand component-level qualification.
• Wide operating temperature: −55 °C to 105 °C range supports deployment in thermally challenging environments without sacrificing performance.
• High ripple tolerance: 300 mA (120 Hz) and 600 mA (10 kHz) ripple current ratings enable effective filtering across a range of switching frequencies.
• Compact form factor: φ10 × 7.7 mm SMD can offers substantial capacitance in a small footprint, aiding miniaturized power delivery designs.
• Long endurance at elevated temperature: 2000 hours at 105 °C provides predictable lifecycle behavior for long-term designs.
• Automated assembly ready: Supplied in embossed carrier taping for compatibility with high-volume pick-and-place manufacturing.
