• Low ESR ESR of 30 mΩ measured at 20 °C, 100 kHz, enabling efficient high-frequency filtering and reduced loss.
• High Ripple Capability Low-frequency ripple current 160 mA at 120 Hz and high-frequency ripple current 1.6 A at 300 kHz, supporting demanding switching environments.
• Temperature & Endurance Operating range −55 °C to 125 °C with a rated lifetime of 3000 hours at 125 °C.
• Leakage & Loss Angle Leakage current specified at 100 µA; tangent of loss angle (tan δ) 0.12 at 20 °C, 120 Hz.
• Package & Assembly Radial can SMD package (φ8 × 7.7 mm) with embossed carrier taping and moisture-proof packing; compatible with lead-free reflow soldering conditions up to a 260 °C peak as specified for the series.

Typical Applications

• SMD power modules — Surface-mount power assemblies that require high allowable ripple current and low ESR benefit from the 1.6 A high-frequency ripple rating and 30 mΩ ESR.
• High-temperature electronics — Designs operating in elevated ambient conditions can leverage the −55 °C to 125 °C range and 3000 hour life at 125 °C for reliable long-term performance.
• High-frequency filtering and decoupling — The low ESR at 100 kHz and specified high-frequency ripple current make this capacitor suitable for decoupling near switching regulators and high-frequency circuits.
• Automated SMD assembly — Compact φ8 × 7.7 mm dimensions with embossed carrier taping and moisture-proof packing streamline pick-and-place and reflow processes.

Unique Advantages

• High ripple handling: 1.6 A at 300 kHz (and 160 mA at 120 Hz) reduces stress in switching applications and supports elevated ripple workloads.
• Low ESR for efficient filtering: 30 mΩ ESR at 100 kHz lowers power loss and improves filtering effectiveness in high-frequency circuits.
• Long high-temperature life: Rated endurance of 3000 hours at 125 °C delivers predictable longevity for thermal-stressed designs.
• Surface-mount assembly ready: Embossed carrier taping and moisture-proof packing support modern SMT production and reflow soldering up to 260 °C peak per series guidance.
• Compact radial can SMD footprint: φ8 × 7.7 mm size provides a small footprint while maintaining high capacitance and ripple capability for space-constrained boards.
