RKS1J470MCNAJLGS

The RKS1J470MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for general-purpose SMD power applications. It provides 47 µF capacitance at a rated voltage of 63 V in a compact φ10 × 12.4 mm can package.

Engineered for high-frequency ripple handling and extended high-temperature life, this Nichicon RKS-series part supports operation across −55 °C to 125 °C and is specified for a 3000-hour endurance at 125 °C, making it suitable for demanding power and decoupling roles on compact PCBs.

Key Features

• Capacitance & Voltage — Rated at 47 µF and 63 V, providing mid-range capacitance for SMD power applications and general-purpose filtering.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ measured at 20 °C/100 kHz and specified high-frequency ripple current of 1.4 A at 300 kHz enable effective high-frequency bypass and decoupling.
• Ripple Current Capability — Low-frequency ripple current of 140 mA at 120 Hz and high-frequency ripple current of 1.4 A at 300 kHz support both mains-frequency smoothing and switching-regulator workloads.
• Wide Temperature & Long Life — Operating range from −55 °C to 125 °C with a rated life of 3000 hours at 125 °C for sustained reliability in high-temperature environments.
• Compact SMD Package — Radial, can-style SMD package with dimensions φ10 × 12.4 mm (D × L) for space-constrained board designs.
• Manufacturing-Ready Packaging — Supplied in embossed carrier taping with moisture-proof packing to support automated surface-mount assembly and storage.
• RoHS Compliant — Meets RoHS directive requirements as indicated in the product documentation.

Typical Applications

• Power Supply Filtering — Provides bulk and decoupling capacitance for switching regulators and intermediate bus filtering where low ESR and high ripple current are required.
• DC–DC Converters — Suited for input/output smoothing in compact converter modules that require stable performance up to 63 V and elevated operating temperatures.
• High-Frequency Power Circuits — Low ESL/ESR characteristics and high-frequency ripple capability make it a fit for circuits with significant high-frequency content.
• General-Purpose SMD Designs — General-purpose surface-mount capacitor for space-constrained assemblies requiring reliable, long-life polymer aluminum capacitance.

Unique Advantages

• Extended High-Temperature Endurance: 3000 hours rated life at 125 °C supports long-term use in hot ambient or board-heated environments.
• High-Frequency Ripple Handling: 1.4 A ripple current at 300 kHz helps reduce heating and maintain performance in switching applications.
• Low ESR (30 mΩ): Minimizes voltage drop and power dissipation under load, improving efficiency in power stages.
• Compact SMD Can: φ10 × 12.4 mm package offers a high-capacitance option for tight PCB layouts without sacrificing performance.
• Production-Friendly Packaging: Embossed carrier taping and moisture-proof packing simplify pick-and-place and storage workflows.
• Predictable Leakage: Specified leakage current of 148 µA supports designs that require defined standby and leakage behavior.
