RKS1V8R2MCNAFEGS

The RKS1V8R2MCNAFEGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series, rated at 8.2 µF and 35 V. It is designed for compact SMD applications that require low ESR and high allowable ripple current while operating across a wide temperature range.

Key characteristics include a temperature range of −55 °C to 125 °C, a rated lifetime of 3000 hours at 125 °C, low ESR (60 mΩ at 100 kHz), and both low- and high-frequency ripple current ratings, making it suitable for demanding power and decoupling roles on densely populated PCBs.

Key Features

• Core Type: Conductive polymer aluminum solid electrolytic construction for stable capacitance and reliable operation across temperature.
• Capacitance & Tolerance: 8.2 µF nominal capacitance with tolerance −20% to +20% (±20% at 120 Hz, 20 °C).
• Voltage Rating: Rated at 35 V for medium-voltage SMD circuits.
• Low ESR Performance: ESR of 60 mΩ measured at 20 °C, 100 kHz to support fast transient response and reduced loss in high-frequency circuits.
• High Ripple Current Capability: Low-frequency ripple current 90 mA (120 Hz) and high-frequency ripple current 900 mA (300 kHz) for sustained duty in ripple‑heavy designs.
• Thermal and Life Reliability: Operating range −55 °C to 125 °C with a rated endurance of 3000 hours at 125 °C.
• SMD Package & Assembly: Radial can SMD package (size φ6.3 × 5.8 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering up to a 260 °C peak.
• Leakage and Dissipation: Leakage current up to 100 µA and tan δ (DF) of 0.12 measured at 20 °C, 120 Hz for predictable dissipation behavior.
• Regulatory: RoHS compliant.

Typical Applications

• High-ripple SMD power stages: Use where elevated ripple currents are present and compact SMD parts are required to meet board space constraints.
• Decoupling and output filtering: Ideal for local decoupling on DC‑DC converter outputs or point-of-load modules needing low ESR and stable capacitance.
• Elevated-temperature electronics: Suited for systems that operate across wide temperature ranges, up to 125 °C, where prolonged life and stability are necessary.
• Compact, high-density PCBs: Radial can SMD package and embossed carrier taping simplify placement on small, densely populated boards.

Unique Advantages

• Low ESR for better transient response: 60 mΩ at 100 kHz reduces voltage drop and heating under high-frequency switching conditions.
• High allowable ripple current: 900 mA at 300 kHz (high frequency) and 90 mA at 120 Hz (low frequency) supports sustained ripple duty without premature degradation.
• High-temperature endurance: Rated for 3000 hours at 125 °C, offering predictable longevity in thermally demanding applications.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated assembly and storage handling.
• Lead-free reflow compatibility: Supports lead-free reflow soldering with a 260 °C peak for modern assembly processes.
• Compact footprint: φ6.3 × 5.8 mm package balances capacitance and board space for tight designs.
