RKS1E8R2MCNAFEGS

The RKS1E8R2MCNAFEGS is a surface‑mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers 8.2 µF capacitance at 25 V in a compact radial can SMD package (φ6.3 × 5.8 mm) for designs that require low ESR and robust ripple handling.

Engineered for elevated temperature operation, the device is specified for a −55 °C to +125 °C operating range and a rated endurance of 3000 hours at 125 °C, making it suitable for applications that demand long life under thermal stress.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic capacitor providing solid electrolyte performance characteristics.
• Capacitance & Tolerance 8.2 µF with a tolerance of −20% to +20% measured at 20 °C, 120 Hz.
• Rated Voltage 25 V nominal rated voltage.
• Low ESR & High‑frequency Performance ESR of 50 mΩ measured at 20 °C, 100 kHz and a dissipation factor (tanδ) of 0.12 at 20 °C, 120 Hz for stable high‑frequency behavior.
• High Ripple Current Capability Low‑frequency ripple current 90 mA (120 Hz) and high‑frequency ripple current 900 mA (300 kHz) for handling switching and AC ripple stress.
• Leakage Current Specified leakage current up to 100 µA after rated voltage application.
• Thermal Endurance Rated load life of 3000 hours at 125 °C; category temperature range −55 °C to +125 °C.
• Package & Assembly Compact φ6.3 × 5.8 mm radial can SMD with embossed carrier taping and moisture‑proof packing; compatible with lead‑free reflow soldering conditions specified to a 260 °C peak.
• Compliance RoHS compliant.

Typical Applications

• Power supply filtering — Smoothing bulk and ripple on DC rails where low ESR (50 mΩ at 100 kHz) and up to 900 mA high‑frequency ripple capability are required.
• Switching regulator decoupling — Local decoupling for DC‑DC converters and switching power stages that generate high‑frequency ripple currents.
• Industrial and embedded electronics — Applications operating across a wide temperature range (−55 °C to +125 °C) and requiring extended life at elevated temperatures (3000 h at 125 °C).

Unique Advantages

• High ripple tolerance: 900 mA at 300 kHz (900 mA HF) and 90 mA at 120 Hz (LF) combined with low ESR support robust handling of switching currents.
• Extended high‑temperature life: 3000 hours at 125 °C provides predictable endurance in thermally demanding environments.
• Compact SMD can footprint: φ6.3 × 5.8 mm package minimizes board area while providing electrolytic capacitance levels.
• Quantifiable AC loss characteristics: tanδ 0.12 at 20 °C/120 Hz and ESR 50 mΩ at 100 kHz offer measurable performance for margin and thermal calculations.
• Production‑oriented packaging: Embossed carrier taping with moisture‑proof packing supports automated placement and standard SMT assembly flows.
• Regulatory compliance: RoHS compliance supports use in assemblies targeting restricted‑substance requirements.
