RKS1C470MCNAHGGS

The RKS1C470MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series, rated 47 µF at 16 V. It is designed for general-purpose SMD power and decoupling duties where low ESR, high ripple tolerance and long-term endurance at elevated temperatures are required.

This part delivers a compact SMD package (L: 7.7 × D: 8 mm) with low equivalent series resistance (30 mΩ @ 100 kHz) and high allowable ripple current (160 mA at 120 Hz, 1.6 A at 300 kHz), making it suitable for dense power electronics and board-level filtering across a wide temperature range (–55 °C to 125 °C).

Key Features

• Capacitance & Tolerance — 47 µF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Voltage Rating — Rated for 16 V DC.
• Low ESR — 30 mΩ equivalent series resistance specified at 100 kHz and 20 °C, enabling effective high-frequency decoupling and reduced power loss.
• High Ripple Current Capability — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) for demanding SMD power applications.
• Leakage Current — Specified leakage current of 100 µA; datasheet condition notes leakage is not more than 0.05CV or 100 µA (whichever is greater) after 2 minutes.
• Wide Temperature & Endurance — Operating range −55 °C to +125 °C with load life of 3000 hours at 125 °C.
• Compact SMD Package — Radial, can-style SMD case with dimensions L: 7.7 × D: 8 mm (φ8 × 7.7 mm) and supplied in embossed carrier taping / moisture-proof packing for automated placement.
• Soldering and Reliability — SMD construction supports lead-free reflow processes (peak temperature profile specified in datasheet) and meets endurance and damp-heat characteristics outlined by the manufacturer.
• Regulatory — Series-level documentation indicates compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Power Filtering — Board-level smoothing and bulk decoupling in general-purpose electronic designs where stable capacitance and low ESR are required.
• High-Frequency Decoupling — SMD decoupling for switching power stages and converters that benefit from low ESR and high HF ripple capability.
• Embedded and Industrial Electronics — Power rail stabilization in compact, thermally demanding assemblies within the specified −55 °C to 125 °C operating range.

Unique Advantages

• Low ESR for Efficient Power Delivery: 30 mΩ ESR at 100 kHz reduces losses and improves voltage stability under fast transient loads.
• High Ripple Handling: Specified LF and HF ripple currents (160 mA at 120 Hz, 1.6 A at 300 kHz) enable use in both mains-frequency filtering and high-frequency switching applications.
• Thermal Endurance: 3000-hour load life at 125 °C supports long-term reliability in elevated-temperature environments.
• Compact SMD Form Factor: φ8 × 7.7 mm footprint in embossed carrier taping supports automated assembly and space-constrained board layouts.
• Predictable Leakage Behavior: Leakage current specified as 100 µA with datasheet conditioning guidance simplifies power budgeting and qualification testing.
• RoHS Compliance: Series-level RoHS alignment supports use in regulated production environments.
