RKS1J470MCNAJJGS

The RKS1J470MCNAJJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 47 µF capacitance at a 63 V rating. Designed for general-purpose electronic power applications, it delivers low ESR and high allowable ripple current in a compact φ10 × 10 mm can SMD package.

Key value comes from its combination of low loss (tanδ = 0.12 at 20°C/120 Hz), high-frequency ripple capability, and a high-temperature endurance rating of 3000 hours at 125°C — attributes that support robust power filtering and decoupling in demanding thermal environments.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with ±20% tolerance and a rated voltage of 63 V, suitable for medium-voltage power rails.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for low loss and stable performance across frequency.
• Low Dissipation Factor — tanδ = 0.12 measured at 20°C, 120 Hz for reduced dielectric losses in AC and ripple conditions.
• Low ESR — Equivalent series resistance of 30 mΩ (measured at 20°C/100 kHz) for improved high-frequency performance and transient response.
• High Ripple Current Capability — Low-frequency ripple current of 140 mA (120 Hz) and high-frequency ripple current of 1.4 A (300 kHz) to handle both bulk and high-frequency smoothing.
• Leakage Current — Specified leakage current of 148 µA for predictable quiescent behavior.
• Robust Temperature and Life Rating — Operating range −55°C to 125°C with an endurance (load life) of 3000 hours at 125°C.
• SMT Can Package — φ10 × 10 mm radial can SMD package supplied in embossed carrier tape with moisture-proof packing for automated assembly.
• Manufacturing Compatibility — SMD, lead-free reflow compatible up to a 260°C peak profile as specified for the series.
• Compliance — RoHS compliant.

Typical Applications

• Power rail decoupling — Low ESR and high ripple-current capability make this part suitable for stabilizing medium-voltage supply rails.
• Switching power supplies — High-frequency ripple handling and low loss support smoothing and filtering in switching converters.
• Industrial electronics — Extended operating range (−55°C to 125°C) and 3000 h endurance at 125°C address demanding thermal environments in industrial systems.

Unique Advantages

• High-temperature endurance: 3000 hours at 125°C provides predictable lifetime behavior under elevated temperature stress.
• Low ESR for high-frequency performance: 30 mΩ at 100 kHz improves transient response and reduces heat generation during ripple currents.
• Broad ripple capability: Specified ripple currents at both low (140 mA at 120 Hz) and high frequency (1.4 A at 300 kHz) enable use across multiple filtering roles.
• SMD-ready packaging: φ10 × 10 mm can in embossed carrier tape with moisture-proof packing supports automated assembly and handling.
• Measured loss characteristics: tanδ = 0.12 at 20°C/120 Hz gives a clear metric for dielectric loss and selection against design requirements.
• Regulatory compliance: RoHS compliance simplifies environmental qualification for production builds.
