RKS1D560MCNAFEGS

The RKS1D560MCNAFEGS is a surface-mount conductive‑polymer aluminum solid electrolytic capacitor from Nichicon’s RKS series. It delivers 56 µF capacitance at a 20 V rating with low ESR and high allowable ripple performance for demanding power applications.

Engineered for high-temperature endurance and automated assembly, this SMD capacitor is suitable for designers who need stable capacitance, low loss, and long life across a wide operating temperature range.

Key Features

• Conductive‑Polymer Aluminum Construction Solid electrolyte design for lower ESR and improved high-frequency performance compared to conventional electrolytics.
• Capacitance and Tolerance 56 µF nominal with ±20% tolerance (–20% to +20%) at 120 Hz, 20 °C.
• Voltage Rating 20 V rated voltage for a variety of low‑voltage power rails.
• Low Loss tanδ (DF) = 0.12 measured at 20 °C, 120 Hz, supporting efficient energy handling in AC conditions.
• Low ESR and High Ripple Capability ESR = 50 mΩ at 20 °C / 100 kHz, with specified ripple currents of 90 mA at 120 Hz and 900 mA at 300 kHz for robust smoothing and decoupling.
• Long Life and Wide Temperature Range Rated for 3,000 hours at 125 °C and an operating temperature range of –55 °C to +125 °C for high‑temperature reliability.
• Leakage Current Specified maximum leakage of 100 µA following standard conditioning procedures.
• SMD Package and Assembly Compact φ6.3 × 5.8 mm can-style SMD package with embossed carrier taping and moisture‑proof packing; compatible with lead‑free reflow soldering conditions to a 260 °C peak.
• RoHS Compliant Conforms to RoHS directive requirements.

Typical Applications

• DC/DC converter output filtering — Low ESR (50 mΩ at 100 kHz) and high allowable ripple current make this part suited for post-regulator smoothing on high-frequency power modules.
• Power-supply decoupling — 56 µF capacitance and low tanδ support stable decoupling on sensitive low-voltage rails to maintain transient response.
• High-frequency switching circuits — High ripple current rating at 300 kHz and conductive‑polymer construction provide reliable performance in switching environments.

Unique Advantages

• High ripple tolerance: 900 mA at 300 kHz and 90 mA at 120 Hz enable effective smoothing in both high- and low-frequency ripple scenarios.
• Low ESR for improved efficiency: 50 mΩ at 100 kHz reduces power loss and heating in power stages.
• Wide temperature endurance: Rated from –55 °C to +125 °C with a 3,000‑hour life at 125 °C for long-term reliability in thermally demanding designs.
• Reflow compatibility: Designed for lead‑free reflow (260 °C peak) and supplied in embossed carrier tape for streamlined surface-mount assembly.
• Compact SMD footprint: φ6.3 × 5.8 mm case size minimizes board area while providing substantial capacitance for low‑voltage applications.
