• Loss Characteristics — tanδ (DF) 0.08 measured at 20°C, 120 Hz, supporting predictable dissipation behavior in AC conditions.
• Ripple Handling — Low-frequency ripple current 835 mA at 120 Hz and high-frequency ripple current 1.67 A at 10 kHz, enabling defined AC current capability across common power-line frequencies.
• Leakage Current — Specified leakage current of 408 µA, providing a measurable baseline for quiescent current budgeting.
• Temperature and Endurance — Operating range −55°C to +105°C with endurance rated for 5000 hours at 105°C, supporting sustained high-temperature operation.
• Automotive Qualification and Compliance — AEC-Q200 rating and RoHS compliant, aligning the component with automotive reliability programs and environmental directives.
• Surface-Mount Packaging — Radial, can-style SMD (φ18 × 16.5 mm L) supplied in embossed carrier taping for automatic mounting; recommended land pattern size 1.83 × 1.83 cm.

Typical Applications

• Automotive Power Electronics — AEC-Q200 qualification and 80 V rating make this capacitor suitable for power rails in automotive electronic systems requiring high-capacitance, high-voltage components.
• High-Temperature Environments — With operation to 105°C and 5000-hour endurance at 105°C, it fits designs that must tolerate sustained elevated temperatures.
• Automated Assembly Workflows — Embossed carrier taping and SMD can packaging enable efficient placement in high-volume manufacturing lines.

Unique Advantages

• High Capacitance at Elevated Voltage: 510 µF at 80 V supports energy storage and smoothing where both capacitance and voltage headroom are required.
• Defined Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz provide designers with clear limits for AC current handling across low- and high-frequency domains.
• Thermal Endurance: 5000 hours at 105°C enables longevity in thermally demanding applications and predictable aging behavior.
• Automotive-Grade Qualification: AEC-Q200 rating and RoHS compliance align the part with automotive reliability and regulatory requirements.
• Pick-and-Place Ready: Embossed carrier taping and an SMD radial-can format streamline automated assembly and reduce handling steps.
• Measurable Leakage and Loss: Clear specifications for leakage current (408 µA) and tanδ (0.08) simplify power budgeting and thermal design.
