RKS1D270MCNAFGGS

The RKS1D270MCNAFGGS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount can package, offering 27 µF capacitance at a 20 V rating. It is engineered for high-frequency and high-ripple-current SMD applications that require low equivalent series resistance and extended high-temperature endurance.

With a wide operating temperature range from −55 °C to 125 °C and a rated load life of 3000 hours at 125 °C, this part targets designs that demand stable capacitance, controlled loss (tan δ), and reliable performance through reflow assembly and in elevated-temperature environments.

Key Features

• Capacitance & Voltage — 27 µF capacitance at a 20 V rated voltage with ±20% tolerance, suitable for compact energy storage needs in SMD form.
• Low Loss / High-Frequency Performance — tanδ = 0.12 (measured at 20 °C, 120 Hz) and ESR = 30 mΩ at 100 kHz, providing low impedance at high frequencies.
• High Allowable Ripple Current — 140 mA at 120 Hz (low frequency) and 1.4 A at 300 kHz (high frequency), supporting circuits with significant AC ripple and fast switching activity.
• Leakage Current — Specified leakage current ≤ 100 µA (after standard conditioning), enabling predictable standby and quiescent behavior.
• Robust Thermal Endurance — Rated for −55 °C to 125 °C with a life/endurance rating of 3000 hours at 125 °C, delivering long-term stability in elevated-temperature applications.
• SMD Package & Assembly Compatibility — Compact φ6.3 × 7.7 mm can (surface-mount), compatible with lead-free reflow soldering (peak temperature up to 260 °C as specified for the series); available in embossed carrier taping with moisture-proof packing for automated assembly.
• Regulatory — RoHS compliant as supplied.

Typical Applications

• High-frequency power circuits — Low ESR at 100 kHz and high allowable ripple current make this capacitor suitable for filtering and smoothing in high-frequency switching environments.
• Power conversion and regulation — Supports DC-DC converters and voltage-regulator modules that require compact bulk capacitance with strong ripple handling.
• Thermally demanding electronics — Rated operation to 125 °C and a 3000-hour endurance at that temperature address applications that operate at elevated ambient or internal temperatures.
• SMD, automated assembly — Designed for surface-mount assembly with embossed carrier taping and reflow compatibility for modern manufacturing flows.

Unique Advantages

• High ripple capability: 1.4 A at 300 kHz and 140 mA at 120 Hz support aggressive switching workloads and reduce the need for parallel parts.
• Low ESR at high frequency: 30 mΩ (100 kHz) lowers losses and improves voltage stability under dynamic loads.
• Extended high-temperature life: 3000 hours at 125 °C provides predictable endurance for long-term thermal reliability.
• SMD convenience: Compact φ6.3 × 7.7 mm can and standardized surface-mount land pattern simplify PCB layout in space-constrained designs.
• Assembly-ready packaging: Embossed carrier taping and moisture-proof packing streamline handling and protect parts through reflow processing.
