RKS1K470MCNAJJGS

The RKS1K470MCNAJJGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon’s RKS series. It delivers 47 µF capacitance at an 80 V rating in a compact φ10 × 10 mm radial can SMD package, designed for general-purpose power applications.

Key attributes include low ESR (30 mΩ at 100 kHz), a high-frequency ripple current capability, and a long endurance rating of 3000 hours at 125°C, making it suitable for demanding thermal and ripple environments in compact SMD assemblies.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance, providing predictable bulk and decoupling performance.
• Low ESR & High Ripple Handling: ESR of 30 mΩ at 20°C/100 kHz and a high-frequency ripple current rating of 1.4 A (300 kHz), enabling efficient filtering and reduced power loss in high-frequency power paths.
• Thermal Endurance: Rated operating temperature range of −55°C to +125°C with a life/endurance specification of 3000 hours at 125°C, supporting sustained operation in elevated-temperature environments.
• Leakage & Loss Characteristics: Specified leakage current of 188 µA and tangent of loss angle (tanδ) of 0.12 (measured at 20°C, 120 Hz), allowing designers to budget for standby current and dissipation.
• SMD Radial Can Package: φ10 × 10 mm size (L: 1 × D: 1 cm) in a radial, can-style SMD case suited to compact board layouts and automated assembly.
• Manufacturing & Handling: Supplied in embossed carrier taping with moisture-proof packing and rated for lead-free reflow soldering (peak 260°C), supporting typical surface-mount assembly processes.

Typical Applications

• DC-DC converter output filtering: Low ESR and 1.4 A high-frequency ripple current rating help smooth converter outputs on 80 V rails.
• High-voltage DC bus decoupling: 80 V rating and compact SMD can format enable decoupling on higher-voltage power rails in space-constrained layouts.
• SMD power modules and boards: φ10 × 10 mm radial can package and embossed carrier taping support automated placement and reflow assembly in module production.
• General-purpose power electronics: Suitable where long endurance at elevated temperature (3000 h at 125°C) and reliable ripple handling are required.

Unique Advantages

• High-voltage SMD option: 80 V rating in a compact SMD can provides a straightforward way to design higher-voltage decoupling without larger through-hole parts.
• Low-loss power filtering: 30 mΩ ESR at 100 kHz and tanδ of 0.12 reduce dissipation and improve efficiency in high-frequency circuits.
• Robust thermal lifetime: 3000 hours at 125°C gives predictable end-of-life planning for designs exposed to sustained high temperatures.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing and 260°C peak reflow compatibility streamline automated manufacturing workflows.
• Measurable leakage and tolerance: Specified leakage current (188 µA) and ±20% capacitance tolerance support precise power-budgeting and component selection.
