RKS1V680MCNAHGGS

The RKS1V680MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series, offering 68 µF capacitance at a 35 V rating. Designed for applications demanding low ESR and high ripple tolerance, it provides a compact SMD can footprint (φ8 × 7.7 mm) and is supplied in embossed carrier taping with moisture-proof packing.

With an operating range from −55 °C to 125 °C and a load-life rating of 3000 hours at 125 °C, this part is targeted at high-frequency power circuits and other power-dense electronics that require reliable decoupling, smoothing and long-term thermal endurance.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a tolerance of −20% to +20% at 20 °C, 120 Hz; rated voltage 35 V.
• Conductive Polymer Construction — Solid conductive polymer electrolyte for stable performance and reduced ESR compared with traditional wet electrolytic types.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ measured at 20 °C, 100 kHz and high-frequency ripple current capability of 1.6 A at 300 kHz, supporting high-speed switching environments.
• Ripple Current & Leakage — Low-frequency ripple current of 160 mA at 120 Hz and specified leakage current of 119 µA.
• Thermal Endurance — Rated for −55 °C to 125 °C with a rated life of 3000 hours at 125 °C.
• Small SMD Can Package — Radial can SMD package with dimensions φ8 × 7.7 mm and recommended land size 8.3 × 8.3 mm for compact PCB layouts.
• Reflow Compatibility & RoHS — SMD type compatible with lead-free reflow profiles (series datasheet specifies peak soldering temperatures up to 260 °C per recommended profiles) and RoHS compliant.
• Dissipation Factor — tan δ of 0.12 measured at 20 °C, 120 Hz.

Typical Applications

• Switching power supplies — Low ESR (30 mΩ at 100 kHz) and high high-frequency ripple current (1.6 A at 300 kHz) make this capacitor suited for output filtering and decoupling in switching regulators.
• DC‑DC converters — Compact SMD can and robust ripple handling support tight power-density designs and post-regulation smoothing.
• Industrial power modules — Wide operating temperature (−55 °C to 125 °C) and 3000-hour life at 125 °C provide endurance for thermally demanding assemblies.

Unique Advantages

• High ripple tolerance: 1.6 A ripple current at 300 kHz enables reliable operation in high-frequency power stages and reduces thermal stress on the capacitor.
• Low ESR for cleaner rails: 30 mΩ ESR at 100 kHz lowers voltage ripple and improves transient response in decoupling applications.
• Thermally robust: Rated for operation to 125 °C with a 3000-hour endurance rating at that temperature, supporting long-term reliability in hot environments.
• Compact SMD footprint: φ8 × 7.7 mm can and recommended land pattern (8.3 × 8.3 mm) help reduce board area while delivering high capacitance.
• Manufacturing-friendly packaging: Supplied in embossed carrier taping with moisture-proof packing for automated placement and storage handling.
