• Robust Temperature & Endurance — Rated for operation from −55 °C to +105 °C with a lifetime/endurance of 5,000 hours at 105 °C.
• Package & Mounting — Chip-type radial can in SMD form factor (φ8 × 10 mm) with surface-mount land size 8.3 × 8.3 mm; supplied on embossed carrier tape for automated placement.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, supporting regulated production requirements.
• Polarized Device — Polarized aluminum electrolytic construction for use where polarity is defined in the circuit.

Typical Applications

• Automotive Electronics — Energy smoothing, decoupling and local bulk capacitance for control modules and power rails in automotive systems, supported by AEC-Q200 qualification and extended temperature rating.
• High-Density PCBs — Surface-mount chip format and embossed carrier taping make this capacitor suitable for automatic placement in compact, densely populated boards.
• Power Rail Filtering — 680 µF capacitance with defined ripple current ratings supports filtering and stabilization of DC power rails in embedded power supplies.
• Industrial Control — Robust endurance at elevated temperature and low leakage current for reliable operation in industrial electronics and control units.

Unique Advantages

• High Capacitance in a Compact SMD Can: 680 µF in a φ8 × 10 mm package provides significant bulk capacitance while saving board area compared to larger discrete solutions.
• Designed for Automated Assembly: Embossed carrier tape packaging enables efficient pick-and-place mounting for high-volume production.
• Engineered for Harsh Environments: −55 °C to +105 °C operating range and 5,000-hour endurance at 105 °C address long-term reliability needs in demanding applications.
• Defined Ripple Performance: Separate low- and high-frequency ripple current specifications (300 mA @120 Hz, 600 mA @10 kHz) allow designers to assess suitability for both mains-frequency and high-frequency switching environments.
• AEC-Q200 Qualification: Series-level qualification supports use in automotive-grade designs where component-level qualification is required.
• Low Leakage and Controlled Loss: Specified leakage current and tan δ provide predictable behavior for energy-sensitive and AC-driven circuits.
