• Low Loss / High-Frequency Performance — tan δ = 0.12 (20 °C, 120 Hz) and ESR of 27 mΩ measured at 20 °C/100 kHz, supporting high-frequency decoupling needs.
• High Allowable Ripple Current — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) to handle switching and high-speed loads.
• Leakage Current — Specified leakage current of 100 µA after standard conditioning.
• Temperature & Endurance — Operating range −55 °C to 125 °C with endurance (load life) of 3000 hours at 125 °C under rated voltage.
• SMD Package & Handling — Radial, can-style SMD package (φ8 × 10 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow up to 260 °C peak per series soldering guidelines.
• RoHS Compliant — Meets the RoHS directive requirements referenced in the product documentation.

Typical Applications

• Power Supply Decoupling — Low ESR and high ripple-current capability make this capacitor suitable for output smoothing and decoupling on DC–DC converters and switching regulators.
• High-Frequency Power Rails — ESR specified at 100 kHz and high-frequency ripple rating support stabilization of fast power rails in communication and data modules.
• Embedded and Industrial Electronics — Long endurance at elevated temperature (3000 hours at 125 °C) supports reliability requirements in compact embedded and industrial control boards.

Unique Advantages

• Measurable Low ESR: 27 mΩ at 100 kHz (20 °C) reduces voltage ripple and improves regulator stability.
• High Ripple Handling: 1.6 A ripple current at 300 kHz supports switching environments and reduces the need for parallel components.
• Extended High-Temperature Life: 3000-hour load life at 125 °C provides predictable long-term performance in high-temperature operating conditions.
• Compact SMD Can Form Factor: φ8 × 10 mm radial SMD package offers high capacitance in a small footprint for space-constrained designs.
• Production-Ready Packaging: Embossed carrier taping with moisture-proof packing streamlines automated assembly and storage handling.
• Reflow-Compatible: Series guidance for lead-free reflow to 260 °C peak enables standard surface-mount assembly processes.
