RKS1V120MCNAFGGS

The RKS1V120MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 12 µF capacitance at a 35 V rating in a compact φ6.3 × 7.7 mm can-style SMD package, designed for high ripple handling and reliable operation across a wide temperature range.

Engineered for power-critical assemblies, this part targets applications that need low ESR, high allowable ripple current and extended high-temperature endurance while supporting lead‑free reflow assembly processes.

Key Features

• Conductive‑polymer solid electrolyte — Solid electrolyte construction for stable electrical characteristics and low equivalent series resistance (ESR).
• Electrical performance — 12 µF capacitance with ±20% tolerance and tanδ 0.12 (measured at 20°C, 120 Hz) for predictable filtering behavior.
• Low ESR and high ripple capability — ESR of 35 mΩ (20°C, 100 kHz) with ripple current ratings of 140 mA at 120 Hz and 1.4 A at 300 kHz to support high-frequency decoupling and power-stage smoothing.
• Leakage and stability — Leakage current specified at 100 µA, supporting low‑leakage designs and predictable bias behavior.
• High-temperature endurance — Rated for continuous operation from −55°C to +125°C with a load life of 3000 hours at 125°C under rated voltage.
• SMD package and assembly — Radial can SMD package (φ6.3 × 7.7 mm) designed for lead‑free reflow processes (peak up to 260°C) and supplied in embossed carrier taping with moisture proof packing for automated assembly.
• Regulatory compliance — RoHS compliant construction.

Typical Applications

• Power-supply decoupling — Low ESR and high ripple current handle switching transients and reduce voltage ripple on DC‑DC converter outputs.
• High-frequency power rails — 35 mΩ ESR at 100 kHz and 1.4 A ripple rating make it well suited for high-frequency smoothing and local energy storage on power stages.
• Industrial and telecom electronics — Extended temperature range (−55°C to +125°C) and 3000 h life at 125°C provide reliability for high‑temperature operating environments.
• Compact SMD assemblies — Small φ6.3 × 7.7 mm SMD can reduces board area while supporting automated lead‑free reflow processes.

Unique Advantages

• Low ESR for improved power integrity: 35 mΩ ESR at 100 kHz supports tighter voltage regulation and lower loss in high-frequency circuits.
• High allowable ripple current: 1.4 A at 300 kHz (and 140 mA at 120 Hz) enables use at both low- and high-frequency stages without overstressing the capacitor.
• Extended high-temperature life: 3000 hours at 125°C under rated voltage for designs that require long-term stability in elevated-temperature environments.
• Assembly-ready SMD format: Can-style radial SMD package and embossed carrier taping with moisture proof packing simplify placement and reflow assembly workflows.
• Predictable leakage and loss: Specified leakage current of 100 µA and tanδ of 0.12 (20°C, 120 Hz) for predictable filter and decoupling behavior.
• RoHS compliant: Built to meet RoHS requirements for regulatory and environmental consistency.
