RKS1C470MCNAHFGS

The RKS1C470MCNAHFGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 47 µF capacitance at 16 V. Designed for general-purpose electronics, it combines low ESR and high ripple-current capability in a compact φ8 × 6.7 mm SMD can.

With a wide operating temperature range (−55 °C to 125 °C) and a rated load life of 3000 hours at 125 °C, this part targets designs that require durable, high-frequency power filtering and stable performance under elevated temperature and ripple stress.

Key Features

• Capacitance & Voltage: 47 µF rated at 16 V with a tolerance of −20% to +20%, suitable for bulk and decoupling roles within its voltage class.
• Conductive-Polymer Electrolyte: Solid polymer construction provides stable electrical characteristics and lower ESR compared with traditional liquid electrolytes.
• Low ESR: ESR of 30 mΩ measured at 20 °C / 100 kHz, enabling efficient high-frequency performance and reduced thermal loss.
• High Ripple Current Capability: Rated for 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency), supporting high-frequency switching and power-stage filtering.
• Leakage Current: Specified leakage current up to 100 µA, supporting low-standby and stable bias performance.
• Robust Endurance: Rated life of 3000 hours at 125 °C under rated voltage, with defined limits on capacitance change, tan δ and ESR after endurance testing.
• Compact SMD Package: φ8 × 6.7 mm radial can SMD package supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliant: Conforms to RoHS requirements as noted in the product data.

Typical Applications

• Power supply filtering: Low ESR and high ripple-current capability make this capacitor suitable for smoothing and filtering in DC–DC converters and regulator outputs.
• High-frequency power stages: The 1.6 A high-frequency ripple rating and low ESR support use near switching elements and point-of-load decoupling.
• Industrial and general electronics: Wide operating temperature (−55 °C to 125 °C) and 3000-hour endurance at 125 °C suit demanding thermal environments in industrial equipment and general-purpose boards.

Unique Advantages

• Stable high-frequency performance: 30 mΩ ESR at 100 kHz delivers lower impedance at switching frequencies, improving regulation and transient response.
• High ripple tolerance: 1.6 A at 300 kHz enables reliable operation in high-speed switching applications without excessive heating.
• Long elevated-temperature life: 3000 hours at 125 °C provides predictable aging characteristics for designs exposed to sustained high temperatures.
• Compact SMD form factor: φ8 × 6.7 mm package supports automated SMT assembly and saves board space compared with larger through-hole cans.
• Low leakage: Maximum leakage specified at 100 µA helps maintain efficiency and bias stability in standby or low-current conditions.
• Manufactured by Nichicon: Part of the RKS series and offered in mass-production status for consistent supply continuity.
