• High Ripple Current Capability: 1.5 A at 120 Hz (low frequency) and 3.0 A at 100 kHz (high frequency) for robust AC load handling.
• Leakage and Polarization: Polarized device with leakage current specified at 500 µA after voltage application.
• Temperature & Endurance: Rated −55 °C to 105 °C with endurance of 2000 hours at 105 °C under rated voltage.
• Compact SMD Package: φ5×6 mm can (radial, can − SMD) with recommended land size 5.3×5.3 mm for automated placement.
• Automotive Qualification: AEC‑Q200 rated for applications requiring automotive‑level component qualification.
• Packaging for Production: Supplied in embossed carrier taping with moisture‑proof packing for SMT assembly.

Typical Applications

• Automotive systems — Designed for automotive applications and qualified to AEC‑Q200 to support reliability requirements in vehicle electronics.
• High‑ripple power filtering — High ripple current ratings at both low and high frequencies make it suitable for smoothing and decoupling on power rails.
• Compact surface‑mount designs — Small φ5×6 mm SMD can enables high capacitance in space‑constrained PCBs and automated assembly.

Unique Advantages

• High capacitance in a small footprint: 180 µF in a φ5×6 mm package supports aggressive component density without sacrificing energy storage.
• Low ESR for improved efficiency: 17 mΩ ESR at 100 kHz reduces conduction losses and improves high‑frequency performance.
• Broad ripple handling: Rated ripple currents of 1.5 A (120 Hz) and 3.0 A (100 kHz) allow use across both low‑ and high‑frequency power domains.
• Automotive‑grade reliability: AEC‑Q200 rating and 2000‑hour endurance at 105 °C provide confidence for long‑life applications.
• Wide operating temperature: −55 °C to 105 °C supports deployment across harsh thermal environments.
• Production‑ready packaging: Embossed carrier taping and moisture‑proof packing simplify SMT line integration and handling.
