• Low ESR — 14 mΩ (measured at 20°C, 100 kHz), reducing conduction loss and improving high-frequency filtering efficiency.
• High Ripple Current Capacity — 555 mA at 120 Hz (low frequency) and 3.7 A at 100 kHz (high frequency) to handle heavy AC ripple and switching noise.
• Leakage Current — Specified at 117.5 µA for predictable standby and quiescent behavior.
• Extended Endurance — Rated life of 4000 hours at 135°C, supporting long-term reliability in hot environments.
• Wide Temperature Range — Operates from −55°C to +135°C, suitable for thermally challenging installations.
• Automotive-Grade Qualification — AEC‑Q200 qualified, addressing requirements for automotive electronics.
• Assembly & Robustness — Surface-mount, vibration-resistant can with embossed carrier taping for automated placement; compact dimensions (φ10 × 12.5 mm / L:1.25 × D:1.00 cm) and defined PCB land size (1.03 × 1.03 cm).
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive power electronics — Bulk filtering and decoupling in on-board power modules where AEC‑Q200 qualification and 135°C endurance are required.
• DC‑DC converters and regulators — Low ESR (14 mΩ) and high ripple-current capability (3.7 A @100 kHz) support switching power stages and output filtering.
• Rugged industrial power systems — Compact SMD format and vibration resistance make this capacitor suitable for harsh environments with wide operating temperatures.

Unique Advantages

• Low impedance at high frequency: 14 mΩ ESR at 100 kHz reduces conduction losses and improves suppression of switching noise.
• High ripple tolerance: 3.7 A (100 kHz) and 555 mA (120 Hz) ripple-current ratings allow sustained operation under heavy AC ripple conditions.
• High-temperature longevity: 4000 hours end-of-life rating at 135°C enables deployment in thermally demanding designs.
• Automotive-ready: AEC‑Q200 qualification supports use in automotive electronics that require recognized component-level reliability.
• Compact SMD package with automated assembly support: Embossed carrier taping and vibration-resistant can help streamline PCB assembly and improve mechanical robustness.
• Predictable leakage and loss characteristics: Specified leakage current (117.5 µA) and tanδ (0.14 at 120 Hz) provide deterministic behavior for system designers.
