RKS1K8R2MCNAFEGS

The RKS1K8R2MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers an 8.2 µF capacitance at an 80 V rating in a compact radial SMD can (φ6.3 × 5.8 mm) designed for general-purpose power and filtering uses.

Key value comes from a wide operating temperature range (−55 °C to 125 °C), low equivalent series resistance (120 mΩ at 100 kHz), and high allowable ripple current (700 mA at 300 kHz), making it suitable for compact, high-voltage SMD power designs that require long-term high-temperature endurance.

Key Features

• Capacitance & Tolerance — 8.2 µF nominal with a tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Rated Voltage — 80 V DC rating for higher-voltage rails and power applications.
• Conductive-Polymer Electrolyte — Solid polymer electrolyte construction with low loss (tan δ = 0.12 at 20 °C, 120 Hz) for stable performance.
• Low ESR & High Ripple Capability — ESR of 120 mΩ at 100 kHz, with 70 mA at 120 Hz (low-frequency) and 700 mA at 300 kHz (high-frequency) allowable ripple currents.
• Temperature & Endurance — Rated for −55 °C to +125 °C and a load life of 3000 hours at 125 °C.
• Leakage Current — Leakage current specified at 100 µA (measured after rated-voltage application conditions in datasheet).
• Package & Mounting — Surface-mount radial can (SMD) with size φ6.3 × 5.8 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Assembly Compatibility — Lead-free reflow soldering compatibility (260 °C peak reflow per manufacturer conditions).
• Environmental Compliance — RoHS compliant.

Typical Applications

• High-voltage power rails — Bulk decoupling and smoothing on 80 V rails where compact, high-voltage SMD capacitors are required.
• Switching power supplies (DC–DC converters) — Low ESR and high HF ripple current support filtering near switching elements to improve efficiency and reduce ripple.
• Industrial and control electronics — Wide −55 °C to 125 °C operating range and 3000-hour endurance at 125 °C for reliable operation in thermally demanding environments.

Unique Advantages

• High-voltage SMD capability: 80 V rating enables use on higher-voltage rails while retaining an SMD form factor.
