Key Features

• Capacitance & Tolerance — 68 µF nominal capacitance with tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Rated Voltage — 50 V DC rating for higher-voltage power rails.
• Low ESR & High Ripple Capability — ESR of 25 mΩ at 20 °C / 100 kHz with high-frequency ripple current rated at 1.6 A (300 kHz) and low-frequency ripple current of 160 mA (120 Hz), suitable for switching regulator smoothing and decoupling.
• Conductive Polymer Construction — Conductive polymer aluminum solid electrolytic design for low loss (tan δ = 0.12 at 20 °C, 120 Hz) and improved performance under AC stress.
• Leakage Current — Specified leakage current of 170 µA, consistent with solid electrolyte behavior.
• High-Temperature Endurance — Rated life of 3000 hours at 125 °C, supporting long-term operation in elevated-temperature assemblies.
• Surface-Mount Radial Can Package — φ10 × 10 mm (L × D) radial can SMD package supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Soldering Compatibility — SMD type designed to withstand lead-free reflow soldering conditions up to 260 °C peak as specified for the series.

Typical Applications

• Power Supply Decoupling — Low ESR and high ripple current capability make this capacitor suitable for smoothing and decoupling on switching regulator outputs and intermediate rails.
• DC‑DC Converters — Compact 68 µF capacitance and 50 V rating support bulk and output capacitors in high-frequency converter stages.
• Industrial Electronics — Long life at 125 °C and a wide −55 °C to 125 °C operating range support use in industrial control and power electronics operating in elevated temperatures.
• Telecom & Networking Power Modules — High-frequency ripple handling and low tan δ help maintain stability and efficiency in telecom power subsystems.

Unique Advantages

• High Ripple Tolerance: 1.6 A HF ripple rating and 25 mΩ ESR minimize heating and voltage ripple in high-frequency applications.
• Extended High-Temperature Life: 3000 hours at 125 °C provides predictable endurance for long-term deployments in hot environments.
• Compact SMD Radial Can: φ10 × 10 mm form factor and embossed carrier taping enable automated PCB assembly while conserving board space.
• Low Loss Performance: tan δ of 0.12 at 20 °C, 120 Hz reduces dissipation in AC conditions and supports stable filter behavior.
• Conductive Polymer Electrolyte: Solid polymer construction combines low ESR with reliable leakage characteristics for robust power designs.
