RPA0J471MCN1GS

The RPA0J471MCN1GS from Nichicon is a surface-mount conductive-polymer aluminum solid electrolytic capacitor in the RPA series, rated at 470 µF and 6.3 V. It delivers low ESR and high ripple-current capability in a compact φ10 × 7.7 mm SMD can, targeting general-purpose electronic designs that require stable capacitance, high-frequency performance, and extended endurance at elevated temperatures.

Key Features

• Electrical performance — 470 µF nominal capacitance with a tolerance of −20% to +20% and a tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz.
• Low ESR — Equivalent series resistance of 18 mΩ measured at 20°C and 100 kHz, enabling efficient high-frequency operation.
• High ripple-current capability — Rated ripple currents of 430 mA at 120 Hz and 4.3 A at 300 kHz, suitable for demanding AC ripple and switching environments.
• Leakage and tolerance — Leakage current specified at 592 µA (after 2 minutes at 20°C) and capacitance tolerance aligned to series specifications.
• Thermal and endurance profile — Operating temperature range from −55°C to +105°C with an endurance (load life) of 2000 hours at 105°C.
• Compact SMD package — φ10 × 7.7 mm radial can SMD package with surface-mount land size 10.3 × 10.3 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Regulatory status — RoHS compliant.

Typical Applications

• General-purpose SMD power circuits — Use where compact, surface-mount bulk capacitance is required within a general-purpose electronic design.
• Switching power supplies and DC–DC converters — Low ESR (18 mΩ) and 4.3 A ripple capability at 300 kHz support high-frequency switching environments.
• Power-rail decoupling — Provides bulk energy storage and AC ripple attenuation across a −55°C to +105°C temperature range for stable rail performance.
• Compact modules and embedded systems — φ10 × 7.7 mm SMD can and embossed carrier taping simplify integration into space-constrained assemblies.

Unique Advantages

• High ripple tolerance: Rated for 4.3 A at 300 kHz, allowing reliable operation in high-frequency switching applications.
• Low-loss AC performance: Tan δ of 0.12 at 120 Hz and 20°C delivers controlled dissipation for stable behavior in AC conditions.
• Low ESR for improved efficiency: 18 mΩ ESR at 100 kHz reduces losses and supports cleaner power delivery in tight designs.
• Extended high-temperature endurance: 2000 hours at 105°C enables sustained performance in thermally demanding environments.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing supports automated surface-mount assembly processes.
• RoHS compliant: Conforms to RoHS requirements for regulatory and environmental compatibility.
