With AEC-Q200 qualification and RoHS compliance, this part targets demanding automotive applications where long endurance, stable filtering, and assembly compatibility are required.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance.
• Low Impedance — Rated impedance of 170 mΩ for improved voltage stability in power rails and decoupling networks.
• Ripple Current Handling — 225 mA at 120 Hz (low frequency) and 450 mA at 10 kHz (high frequency) for effective smoothing under varying load conditions.
• Leakage Current — Specified leakage current of 47 µA to limit standby losses.
• Endurance & Temperature Range — Designed for operation from −55 °C to +105 °C with a rated life of 5000 hours at 105 °C.
• High-Temperature Reflow Compatibility — Chip type capable of 260 °C peak reflow (recommended reflow condition: 260 °C peak for 5 s; 230 °C over 60 s) for modern SMT processes.
• Surface-Mount Package — φ8 × 10L radial can (SMD) package, surface-mount land size 8.3 × 8.3 mm, supplied in embossed carrier taping for automatic placement.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant for regulated environments and automotive-grade designs.

Typical Applications

• Automotive power modules — Bulk filtering and decoupling in automotive electronic assemblies where AEC-Q200 qualification and 105 °C endurance are required.
• High-density PCB assemblies — Surface-mount chip form factor and embossed carrier taping enable placement on compact, densely populated boards.
• Power rail smoothing — Low impedance and specified ripple current ratings support stable DC bus and local decoupling on 10 V rails.

Unique Advantages

• Engineered for elevated temperatures — 5000-hour life at 105 °C provides long-term stability in hot operating environments.
• Assembly-ready — 260 °C peak reflow compatibility and embossed carrier taping streamline SMT assembly and reflow processes.
• Reliable performance under ripple — Defined low- and high-frequency ripple current ratings help maintain capacitance under dynamic loads.
• Automotive-grade qualification — AEC-Q200 rating supports use in applications requiring automotive-level component reliability.
• Compact SMD can package — φ8 × 10L package offers high capacitance in a surface-mount form factor suitable for space-constrained designs.
