RKS1V180MCNAFGGS

The RKS1V180MCNAFGGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series. It delivers 18 µF capacitance at a 35 V rating with low ESR and high allowable ripple current in a compact radial can SMD package.

Designed for SMD assembly and elevated operating conditions, this capacitor targets compact power delivery and decoupling needs where long life at high temperature and robust ripple handling are required.

Key Features

• Core Technology — Conductive polymer aluminum solid electrolyte construction for stable electrical characteristics and low ESR.
• Electrical Performance — 18 µF capacitance with ±20% tolerance and tanδ = 0.12 (measured at 20°C, 120 Hz).
• Rated Voltage — 35 V working voltage suitable for a variety of power rail applications.
• Low ESR & High Ripple Capability — ESR of 35 mΩ at 20°C/100 kHz and high frequency ripple current up to 1.4 A (300 kHz); low-frequency ripple current rating of 140 mA (120 Hz).
• Leakage & Reliability — Leakage current specified at 100 µA; load life/endurance rated to 3000 hours at 125°C.
• Thermal Range & Solder Compatibility — Operating temperature range −55°C to +125°C and SMD lead-free reflow compatibility (260°C peak correspondence as specified for the series).
• Compact SMD Package — Radial can SMD package, size φ6.3 × 7.7 mm (L × D) with recommended land pattern 6.6 × 6.6 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Standards — RoHS compliant.

Typical Applications

• Power conversion and decoupling — Intended where low ESR and high allowable ripple current improve stability and transient response on DC‑DC converter outputs and power rails.
• High-frequency filtering — Effective in circuits that require reliable high-frequency ripple handling thanks to 35 mΩ ESR at 100 kHz and a 1.4 A high-frequency ripple rating.
• Compact SMD power modules — Suited to space-constrained surface-mount designs that require elevated temperature endurance and automated placement packaging.

Unique Advantages

• High ripple tolerance: 1.4 A high-frequency ripple rating and low ESR reduce voltage ripple and heat generation under dynamic loads.
• Extended high-temperature life: 3000 hours endurance at 125°C enables longer service life in thermally demanding assemblies.
• Compact SMD form factor: φ6.3 × 7.7 mm radial can SMD package provides high capacitance density for board-level space savings.
• Manufacturing-ready packaging: Embossed carrier taping and moisture-proof packing support automated pick-and-place and reflow processes.
• Measurable performance metrics: Specified tanδ, ESR, leakage current, and ripple current values make electrical trade-offs and thermal design straightforward.
