RKS1V270MCNAFGGS

The RKS1V270MCNAFGGS is a surface-mount conductive polymer aluminum electrolytic capacitor in Nichicon’s RKS series, offering 27 µF capacitance at a 35 V rating. It is designed for SMD assemblies that require low equivalent series resistance (ESR), high allowable ripple current, and extended high-temperature endurance.

Key value comes from a compact radial-can SMD package (φ6.3 × 7.7 mm), low ESR (35 mΩ at 100 kHz), and a rated operating range of −55 °C to 125 °C with a life of 3000 hours at 125 °C, making it suitable for demanding board-level power and decoupling applications where robustness and thermal endurance matter.

Key Features

• Capacitance & Voltage: 27 µF, rated for 35 V DC with capacitance tolerance ±20% at 120 Hz, 20 °C.
• Low Loss / Low ESR: Tangent of loss angle (tan δ) 0.12 at 20 °C, 120 Hz; ESR 35 mΩ measured at 100 kHz and 20 °C for improved efficiency in high-frequency applications.
• High Ripple Current Capability: Low-frequency ripple current 140 mA at 120 Hz and high-frequency ripple current 1.4 A at 300 kHz to support switching and high-frequency decoupling needs.
• High-Temperature Endurance: Rated for −55 °C to 125 °C with a load life of 3000 hours at 125 °C, supporting long-term operation under elevated temperature stress.
• Surface-Mount Radial Can Package: Compact φ6.3 × 7.7 mm SMD can (package case: radial, can - SMD) with recommended land size L: 6.6 × W: 6.6 mm; packaged in embossed carrier taping with moisture-proof packing for automated assembly.
• Leakage Current: Specified leakage current of 100 µA.
• Reflow-Compatible: SMD construction supports lead-free reflow soldering conditions (peak up to 260 °C as specified for the series).
• RoHS Compliant: Conforms to RoHS requirements.

Typical Applications

• Reflow-soldered SMD assemblies: Designed for assembly processes requiring lead-free reflow compatibility and embossed carrier taping for pick-and-place.
• High-frequency power decoupling: Low ESR and 1.4 A high-frequency ripple current capability suit decoupling and filtering in high-frequency switching circuits.
• High-temperature electronics: Long life at elevated temperatures (3000 h at 125 °C) makes it appropriate for designs exposed to sustained high operating temperatures.

Unique Advantages

• High-temperature reliability: 3000-hour endurance at 125 °C provides predictable performance for thermally demanding designs.
• Improved power handling: High allowable ripple currents at both low and high frequencies reduce thermal stress on the component and the board.
• Low ESR for better efficiency: 35 mΩ ESR at 100 kHz and a low tan δ help minimize loss and voltage drop in high-frequency applications.
• SMD-friendly packaging: Compact radial-can SMD form factor with embossed taping and moisture-proof packing supports automated assembly and inventory handling.
• Reflow capable: Compatible with lead-free reflow profiles (peak up to 260 °C) used in modern surface-mount production.
• Regulatory compliance: RoHS-compliant construction simplifies environmental compliance for finished products.
