UCD1C331MNS1GS

The UCD1C331MNS1GS is a chip type aluminum electrolytic capacitor engineered for surface-mount assembly. It delivers 330 µF capacitance at 16 V in a compact φ8 × 10 mm SMD can, optimized for high‑density PCBs and automatic placement from embossed carrier tape.

Designed for robust operation up to 105°C and AEC‑Q200 qualification, this low‑impedance capacitor addresses demanding environments that require extended endurance, vibration resistance and reliable ripple handling.

Key Features

• Electrical Performance  330 µF capacitance at 16 V with capacitance tolerance of −20% to +20%; tangent of loss angle (tanδ) 0.16 measured at 20°C, 120 Hz.
• Ripple Current Capability  Rated low-frequency ripple current 300 mA (120 Hz) and high-frequency ripple current 600 mA (10 kHz) to support transient and switching loads.
• Leakage Current  Leakage current specified at 52.8 µA, measured after rated voltage application conditions.
• High-Temperature Endurance  Life rating of 5000 hours at 105°C under rated voltage, providing predictable long-term performance at elevated temperatures.
• Reliability & Qualification  AEC‑Q200 rating and RoHS compliance indicate suitability for regulated and reliability-sensitive designs.
• Compact SMD Package  Chip-type radial can SMD in φ8 × 10L size (L: 1.0 cm, D: 0.8 cm) with surface-mount land recommendation of 8.3 × 8.3 mm; supplied in embossed carrier taping for automatic mounting.
• Mechanical Robustness  Vibration resistant construction suitable for assemblies subject to mechanical stress.

Typical Applications

• Automotive electronic systems — Matches AEC‑Q200 qualification, 16 V rating and 105°C endurance for use in vehicle electronics where regulated qualification and long life are required.
• SMD high-density assemblies — Chip-type radial can and embossed carrier taping support automatic placement on compact, densely populated PCBs.
• Power module and converter boards — 330 µF capacitance combined with rated ripple currents supports energy storage and ripple management in compact power circuits.

Unique Advantages

• Low-impedance performance: Tangent of loss angle of 0.16 (16 V, 120 Hz, 20°C) and specified ripple currents deliver effective impedance control for transient and switching environments.
• Long endurance at elevated temperature: Rated for 5000 hours at 105°C under rated voltage, enabling reliable operation in high-temperature applications.
• AEC‑Q200 qualified and RoHS compliant: Provides qualification and environmental compliance required for regulated and rugged designs.
• Automatic-assembly ready: Embossed carrier taping and surface-mount can style simplify PCB assembly and reduce manual handling.
• Vibration resistant: Mechanical design supports use in environments with mechanical stress or vibration.
• Compact footprint: φ8 × 10 mm chip package fits space-constrained boards while providing 330 µF of capacitance at 16 V.
