RKS1C471MCNAJLGS

The RKS1C471MCNAJLGS from Nichicon is a surface-mount conductive-polymer aluminum solid electrolytic capacitor in the RKS series, specified at 470 µF and 16 V. Designed for general-purpose electronic designs, it combines high capacitance and low impedance in a compact SMD radial can footprint.

Key value propositions include high allowable ripple current, low equivalent series resistance, and extended load life up to 3000 hours at 125°C—features aimed at applications that require reliable power decoupling and sustained performance at elevated temperatures.

Key Features

• Capacitance and Voltage — 470 µF nominal capacitance with a rated voltage of 16 V and a tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Conductive-Polymer Electrolyte — Solid aluminum construction with conductive polymer electrolyte for stable performance and reduced leakage versus traditional wet electrolytics.
• Low ESR — ESR specified at 20 mΩ (measured at 100 kHz, 20°C) to support low-impedance power paths and improve high-frequency behavior.
• High Ripple Current — Rated ripple current of 200 mA at 120 Hz (low frequency) and 2 A at high frequency (300 kHz), enabling effective smoothing in high-current, high-frequency circuits.
• Wide Operating Temperature — Specified operating range from -55°C to 125°C, with a rated load life of 3000 hours at 125°C.
• Compact SMD Package — Radial, can-style SMD package with dimensions φ10 × 12.4 mm (L: 12.4 mm × D: 10 mm), supplied in embossed carrier taping with moisture-proof packing for assembly compatibility.
• Leakage Current — Specified leakage current of 376 µA, measured after rated voltage application per datasheet conditioning procedures.

Typical Applications

• Power supply decoupling — Provides bulk capacitance and low impedance for local smoothing on DC power rails in compact electronic assemblies.
• High-frequency power modules — Low ESR and high ripple-current capability support output filtering and stability in switching regulators and power modules.
• Industrial and general-purpose electronics — Long load life at elevated temperature makes it suitable for designs requiring sustained performance up to 125°C.

Unique Advantages

• High capacitance in an SMD can — 470 µF in a φ10 × 12.4 mm package reduces board space compared with larger discrete solutions.
• Low impedance at high frequency — 20 mΩ ESR at 100 kHz helps minimize voltage ripple and improves transient response in power circuits.
• Robust ripple handling — Rated ripple currents (200 mA @120 Hz and 2 A @300 kHz) support both low-frequency bulk smoothing and high-frequency decoupling needs.
• Extended high-temperature life — 3000-hour endurance at 125°C provides predictable performance and design longevity in hot environments.
• Assembly-ready packaging — Supplied in embossed carrier taping with moisture-proof packing for automated SMD assembly and handling.
