• Low Impedance Chip Type — Chip-type construction optimized for low impedance performance; specified tangent of loss angle (tanδ) is 0.08 (measured at 20°C, 120 Hz).
• High Ripple-Current Capability — Rated low-frequency ripple current 458.5 mA at 120 Hz and high-frequency ripple current 917 mA at 10 kHz for demanding power circuits.
• Leakage Current — Specified leakage current of 376 µA after standard application conditions.
• Wide Temperature & Endurance — Operates from -55°C to +105°C with a lifetime/endurance rating of 5000 hours at 105°C.
• Package & Assembly — Surface-mount radial can (φ18 × 16.5 mm) with embossed carrier taping compatible with automatic mounting machines; recommended land size L 1.83 × W 1.83 cm.
• Automotive-Grade Qualification — AEC‑Q200 qualified for applications requiring automotive-level component qualification.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive power systems — AEC‑Q200 qualification and 80 V rating make it suitable for board-level energy buffering and smoothing on automotive electronic control units and power modules.
• High-density power assemblies — Chip-type SMD can and embossed carrier taping support automated placement on compact, densely populated PCBs.
• High-voltage DC-link and smoothing — 470 µF at 80 V with substantial ripple-current ratings for DC-link, bulk filtering and power conditioning in higher-voltage subsystems.

Unique Advantages

• High-voltage, high-capacitance in a compact SMD form — Delivers 470 µF at 80 V in a φ18 × 16.5 mm SMD can, balancing energy density and board-space efficiency.
• Low impedance for effective filtering — Chip-type construction and a low tanδ support effective decoupling and smoothing in power paths.
• Robust ripple-handling — Distinct low- and high-frequency ripple-current specifications (458.5 mA at 120 Hz; 917 mA at 10 kHz) enable reliable performance across a range of switching environments.
• Wide temperature endurance — Rated for -55°C to +105°C and specified for 5000 hours at 105°C to address long-term operation in harsh conditions.
• Designed for automated surface-mount assembly — Embossed carrier taping and SMD can package facilitate efficient pick-and-place and reflow-compatible processes.
• Automotive-grade qualification and compliance — AEC‑Q200 qualification and RoHS compliance support use in regulated applications with traceable component quality.
