RDS1C470MCNAFEGS

The RDS1C470MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RDS series. It delivers 47 µF capacitance at 16 V with a compact φ6.3×5.7 mm SMD can package and is designed for applications that require high capacitance, high ripple handling and reliable operation at elevated temperatures.

Key value propositions include high ripple-current capability (up to 1.8 A at 300 kHz), low ESR (24 mΩ at 100 kHz), and extended load life rated to 3000 hours at 125°C, enabling robust performance in thermally demanding power circuits.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for stable capacitance and reliable electrical characteristics.
• Capacitance and tolerance — 47 µF with ±20% tolerance (–20% to +20%) measured at 120 Hz, 20°C.
• Voltage rating — 16 V rated voltage with corresponding leakage current specification of up to 700 µA (per datasheet condition).
• High ripple-current capability — Rated ripple current up to 1.8 A at 300 kHz and 180 mA at 120 Hz, supporting high-frequency and low-frequency ripple environments.
• Low ESR — Equivalent series resistance of 24 mΩ at 100 kHz (20°C), improving efficiency in decoupling and filtering roles.
• Extended high-temperature life — Load life rated 3000 hours at 125°C at rated voltage, with defined endurance limits for capacitance, tan δ and ESR.
• Wide operating temperature — Specified for –55°C to +125°C operation.
• SMD package and assembly — φ6.3×5.7 mm radial can SMD (case code FE) compatible with lead-free reflow soldering; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS compliant — Conforms to RoHS directive as noted in product documentation.

Typical Applications

• Power rail smoothing — Provides bulk capacitance and low ESR for smoothing DC rails where elevated temperature and high ripple are present.
• High-frequency decoupling — Supports high-frequency ripple currents (1.8 A at 300 kHz) for switching power stages and DC–DC converters.
• Thermally demanding electronics — Rated for 3000 hours at 125°C, suitable for circuits that must maintain capacitance and ESR under extended high-temperature stress.

Unique Advantages

• High ripple tolerance: 1.8 A ripple-current rating at 300 kHz helps reduce heating and improves reliability in high-frequency power circuits.
• Compact SMD can: φ6.3×5.7 mm footprint provides substantial capacitance in a small surface-mount package for space-constrained board designs.
• Long high-temperature life: 3000-hour endurance at 125°C offers predictable performance over extended operation in hot environments.
• Low ESR: 24 mΩ at 100 kHz lowers voltage drop and power loss, improving efficiency in power delivery networks.
• Assembly-ready packaging: Supplied in embossed carrier tape with moisture-proof packing for automated SMT assembly and handling.
