The UCD1V331MNL1GS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount applications. With a rated capacitance of 330 µF and a 35 V rating, it targets compact power decoupling and bulk energy storage in dense board designs.

Engineered for rugged environments, this part delivers AEC-Q200 qualification, RoHS compliance, and a broad operating temperature range from −55 °C to +105 °C, making it suitable for systems that require stable filtering and power conditioning under thermal stress.

Key Features

• Capacitance & Voltage: 330 µF rated capacitance with a 35 V voltage rating and ±20% tolerance (measured at 120 Hz, 20 °C), providing predictable energy storage for power rail support.
• Low Impedance Performance: Chip-type, low-impedance construction for improved AC performance; tangent of loss angle (tan δ) is 0.12 at the rated 35 V (120 Hz, 20 °C), supporting efficient ripple handling.
• Ripple Current Capability: Designed for both low- and high-frequency ripple—425 mA at 120 Hz and 850 mA at 10 kHz—enabling effective smoothing in switching regulator and power conversion circuits.
• Reliability & Endurance: Rated endurance of 5000 hours at 105 °C with defined limits for capacitance change, tan δ, and leakage current, supporting long-term thermal stress performance.
• Operating Range & Leakage: Wide operating temperature range −55 °C to +105 °C and specified leakage current of 115.5 µA, allowing predictable behavior across temperature extremes.
• Package & Mounting: Chip-type radial can in an SMD form factor, size φ10 × 10L (1.0 × 1.0 cm), surface-mount land size 1.03 × 1.03 cm, and supplied in embossed carrier taping compatible with automatic mounting machines.
• Industry Qualification & Compliance: AEC-Q200 qualified and RoHS compliant, supporting use in qualified electronic applications requiring recognized component-level reliability.

Typical Applications

• Power Supply Filtering: Bulk and decoupling capacitor for DC–DC converters and regulator output stages, leveraging high capacitance and strong ripple-current handling.
• Embedded and Industrial Electronics: Energy smoothing and transient suppression in compact, board-level power systems operating in wide temperature conditions.
• Automotive Electronics: Capacitor for power conditioning in vehicle electronic modules where AEC-Q200 qualification and extended temperature performance are required.

Unique Advantages

• High Capacitance in a Compact SMD Can: 330 µF in a φ10 × 10L package reduces board area while providing substantial energy storage for power rails.
• Dual-Frequency Ripple Performance: Specified ripple current at both 120 Hz and 10 kHz supports mixed-frequency power systems, improving filtering across a broad spectrum.
• Temperature and Endurance Rated: 5000 hours at 105 °C endurance specification and −55 °C to +105 °C operating range for reliable long-term operation in thermally demanding applications.
• Assembly-Friendly Supply: Supplied in embossed carrier taping and compatible with automatic mounting machines to streamline pick-and-place production flows.
• Qualified and Compliant: AEC-Q200 qualification and RoHS compliance help meet regulatory and reliability requirements in regulated and safety-conscious markets.
