RKS1D470MCNAFEGS

The RKS1D470MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon's RKS series. Engineered for high allowable ripple current and low equivalent series resistance (ESR), it targets SMD power circuits and assemblies requiring stable filtering and bulk capacitance in compact packages.

Key characteristics include 47 µF capacitance at a 20 V rating, robust high-temperature endurance (3000 hours at 125°C), and compatibility with lead-free reflow processes up to a 260°C peak. The part is supplied in embossed carrier taping with moisture-proof packing and is in mass production.

Key Features

• Core Technology  Conductive polymer aluminum solid electrolytic construction delivers low ESR and stable performance across temperature.
• Electrical Performance  47 µF capacitance at 20 V with tolerance -20% to +20% and tanδ of 0.12 (20°C, 120 Hz) for predictable impedance characteristics.
• Low ESR & Ripple Handling  ESR of 50 mΩ measured at 20°C/100 kHz; low-frequency ripple current 90 mA (120 Hz) and high-frequency ripple current 900 mA (300 kHz) for demanding ripple environments.
• Leakage Current  Leakage current specified at 100 µA, supporting predictable bias behavior after voltage application.
• High-Temperature Endurance  Rated for 3000 hours at 125°C, with operating temperature range of -55°C to 125°C for elevated-temperature applications.
• Reflow-Compatible SMD Package  Radial can SMD (φ6.3 × 5.8 mm) designed for surface-mount assembly and validated for lead-free reflow soldering (260°C peak correspondence).
• Packaging & Production  Supplied in embossed carrier taping with moisture-proof packing; product status: mass production.
• RoHS Compliance  Conforms to RoHS directive requirements.

Typical Applications

• Surface-mount power modules  Suitable for SMD assemblies that require reflow soldering compatibility and compact bulk capacitance.
• High-ripple current circuits  Low ESR and rated ripple currents (90 mA @120 Hz, 900 mA @300 kHz) make it appropriate where ripple handling is needed.
• Elevated-temperature designs  Use in assemblies operating up to 125°C where long life and endurance (3000 h at 125°C) are required.

Unique Advantages

• Low impedance at high frequency: ESR of 50 mΩ at 100 kHz provides reduced voltage ripple and improved filtering effectiveness in high-frequency paths.
• Proven high-temperature endurance: 3000-hour life at 125°C supports long-term stability in thermally demanding environments.
• Reflow-ready SMD format: φ6.3 × 5.8 mm radial can design and lead-free reflow compatibility enable automated surface-mount assembly flows.
• Predictable leakage and loss characteristics: Specified leakage current (100 µA) and tanδ (0.12) at standard test conditions help simplify design margining and validation.
• Production-ready packaging: Embossed carrier taping with moisture-proof packing facilitates handling, storage, and pick-and-place processing.
