RKS1D470MCNAFGGS

The RKS1D470MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in a compact radial can (SMD) package. It delivers 47 µF capacitance at 20 V with a polymer electrolyte, designed for applications that require low equivalent series resistance and high ripple-current capability.

With a wide operating range of −55°C to 125°C, a rated life of 3000 hours at 125°C, and lead-free reflow compatibility up to 260°C peak, this part is suited for high-frequency power-decoupling and power-conversion applications where temperature endurance and predictable electrical performance are required.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with tolerance −20% to +20% at 120 Hz, rated for 20 V operation.
• Conductive Polymer Electrolyte: Solid polymer construction for stable impedance characteristics and reliable performance under high-frequency load.
• Low ESR: 30 mΩ equivalent series resistance measured at 100 kHz, 20°C—supporting efficient high-frequency decoupling.
• High Ripple-Current Capability: 140 mA allowable ripple at 120 Hz and 1.4 A allowable ripple at 300 kHz, enabling use in switching and high-frequency circuits.
• Temperature & Endurance: Operating range −55°C to 125°C with a rated life of 3000 hours at 125°C.
• Leakage Current: Specified leakage current up to 100 µA (after 2 minutes’ application of rated voltage conditions as defined in the datasheet).
• Compact SMD Can: Size φ6.3 × 7.7 mm (D × L) with surface-mount land size 6.6 × 6.6 mm—offers a small footprint for board-level designs.
• Reflow & Packaging: Lead-free reflow compatible (260°C peak) and supplied in embossed carrier tape with moisture-proof packing for automated assembly.
• Regulatory Compliance: RoHS compliant as specified in the product documentation.

Typical Applications

• Switching Power Supplies: Low ESR and high high-frequency ripple-current rating make this capacitor suitable for switching node decoupling and output filtering.
• Point-of-Load Decoupling: Compact SMD can provides local energy storage and noise suppression for DC–DC converters and regulator modules.
• High-Frequency Power Circuits: Measured ESR at 100 kHz and specified HF ripple current support use in high-frequency converter and inverter stages.
• Industrial Electronics: Extended temperature range to 125°C and a 3000-hour endurance rating at 125°C support demanding thermal environments.

Unique Advantages

• High ripple-current handling: Rated for 1.4 A at high frequency and 140 mA at low frequency, allowing reliable operation under demanding switching loads.
• Low impedance at high frequency: 30 mΩ ESR at 100 kHz reduces voltage ripple and improves transient response in power stages.
• Thermal endurance: Broad −55°C to 125°C range and 3000-hour life at 125°C provide predictable long-term performance in hot environments.
• SMD can footprint: φ6.3 × 7.7 mm package balances capacitance with a compact board footprint for space-constrained designs.
• Assembly-ready packaging: Embossed carrier tape with moisture-proof packing and lead-free reflow compatibility streamline automated PCB assembly.
• Stable leakage and tolerance: Leakage current specified at 100 µA and ±20% capacitance tolerance at 120 Hz give designers clear electrical margins for circuit design.
