UCD2A680MNS1MS

The UCD2A680MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount applications. It delivers 68 µF capacitance at a 100 V rating in a compact SMD can package suitable for high-density PCB assemblies.

Engineered for reliability in demanding environments, this part features a wide operating temperature range of -55 °C to 105 °C, AEC-Q200 qualification, RoHS compliance, and long endurance (5,000 hours at 105 °C), making it well suited for automotive and industrial power electronics requiring robust filtering and decoupling.

Key Features

• Electrical Performance — 68 µF nominal capacitance with a tolerance of -20% to +20% and a rated voltage of 100 V, providing high-voltage energy storage in a compact SMD form factor.
• Low Loss / Low Impedance — tanδ (DF) of 0.07 measured at 20 °C, 120 Hz, indicating low dissipation for improved AC performance in filtering and decoupling roles.
• Ripple Handling — Specified ripple currents of 250 mA at 120 Hz (low frequency) and 500 mA at 10 kHz (high frequency) for effective smoothing in power-supply applications.
• Leakage — Leakage current specified at 68 µA, supporting predictable quiescent behavior in precision circuits.
• Reliability & Endurance — Rated for 5,000 hours at 105 °C (life/endurance), with specified limits on capacitance change, tanδ increase, and leakage after endurance testing.
• Automotive-Grade Qualification — AEC-Q200 qualified and designed for automotive use cases in addition to industrial applications.
• Robust Environmental Range — Operates from -55 °C to 105 °C and is vibration resistant for harsh-environment installations.
• SMD Chip Package & Assembly — Chip-type, surface-mount radial can (φ12.5 × 13.5L) packaged in embossed carrier tape compatible with automatic mounting machines for high-volume PCB assembly.
• Compliance — RoHS compliant.

Typical Applications

• Automotive power modules — Bulk filtering and decoupling in control units where AEC-Q200 qualification and 105 °C endurance are required.
• DC–DC converters and power supplies — Energy storage and smoothing at up to 100 V, leveraging low impedance and defined ripple-current ratings for reliable performance.
• Industrial power electronics — Filtering and transient buffering in compact SMD layouts exposed to wide temperature ranges and vibration.

Unique Advantages

• High-voltage capability: 100 V rating enables use in higher-voltage circuits without sacrificing compact SMD packaging.
• Low loss at operating frequency: tanδ of 0.07 at 120 Hz (20 °C) helps minimize heat generation and improves AC performance in filtering roles.
• Defined ripple performance: Separate low- and high-frequency ripple current specifications (250 mA @120 Hz, 500 mA @10 kHz) allow predictable thermal and electrical design margins.
• Long life at elevated temperature: 5,000-hour endurance at 105 °C supports extended field life in thermally demanding applications.
• Automated assembly ready: Embossed carrier taping and chip-type SMD package facilitate high-speed placement for volume production.
• Qualification and compliance: AEC-Q200 qualification and RoHS compliance address industry and environmental requirements.
