RKS1D680MCNAHHGS

The RKS1D680MCNAHHGS is a surface-mount conductive-polymer aluminum electrolytic capacitor from Nichicon's RKS series, rated 68 µF at 20 V. It combines low ESR and high allowable ripple current in a compact φ8 × 8.7 mm can-style SMD package, designed for demanding power and high-frequency decoupling roles in industrial and electronic systems.

With a wide operating range from −55°C to 125°C and a rated load life of 3000 hours at 125°C, this part targets applications that require reliable high-temperature endurance and consistent performance under sustained ripple and thermal stress.

Key Features

• Capacitance and Voltage — 68 µF capacitance at a 20 V rated voltage with polarization suitable for DC power applications.
• Low ESR and High-Frequency Performance — ESR of 30 mΩ measured at 20°C/100 kHz and tanδ of 0.12 (20°C, 120 Hz), delivering low loss and effective high-frequency decoupling.
• High Allowable Ripple Current — Low-frequency ripple 160 mA at 120 Hz and high-frequency ripple 1.6 A at 300 kHz, enabling robust filtering in switching power stages.
• Leakage and Reliability — Specified leakage current of 100 µA and an endurance rating of 3000 hours at 125°C for long-term stability under elevated temperature.
• Temperature Range — Operational from −55°C to 125°C to support thermally challenging environments.
• Surface-Mount Can Package — Radial can SMD (φ8 × 8.7 mm) optimized for PCB assembly; packaged in embossed carrier taping with moisture-proof packing.
• Reflow Compatibility and RoHS — SMD type compatible with lead-free reflow profiles up to a 260°C peak and compliant with RoHS (per series datasheet information).

Typical Applications

• Power Supply Filtering — Local bulk and output filtering for switching regulators where low ESR and high ripple capability reduce voltage ripple and heat generation.
• High-Frequency Decoupling — Decoupling for DC–DC converters and power modules operating at high switching frequencies, leveraging low ESR at 100 kHz and specified HF ripple rating.
• Industrial Electronics — Power conditioning and filtering in industrial systems that require operation up to 125°C and long life under thermal stress.
• Compact SMD Power Designs — Situations that need high capacitance in a small can-style surface-mount package with tape-and-reel friendly packaging for automated assembly.

Unique Advantages

• High ripple tolerance: Specified 1.6 A HF ripple and 160 mA LF ripple reduce the need for parallel components in many power designs.
• Low-loss polymer electrolyte: 30 mΩ ESR at 100 kHz and tanδ 0.12 lower dissipation and improve thermal performance in tightly packed PCBs.
• Extended high-temperature life: 3000 hours at 125°C provides predictable aging and reliability for long-term deployments in warm environments.
• Compact SMD can form-factor: φ8 × 8.7 mm package delivers high capacitance density while remaining compatible with surface-mount assembly processes.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing simplifies handling and supports automated placement workflows.
