RKS1H100MCNAFEGS

The RKS1H100MCNAFEGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It delivers 10 µF capacitance at a 50 V rating with a compact φ6.3 × 5.8 mm footprint and is supplied in embossed carrier taping with moisture-proof packing.

Designed for applications that demand low equivalent series resistance, high allowable ripple current and extended high-temperature endurance, this SMD capacitor offers a combination of low ESR (80 mΩ at 100 kHz), high-frequency ripple capability (750 mA at 300 kHz) and a rated operating range of −55 °C to 125 °C with 3000 hours life at 125 °C.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic capacitor as specified in the product datasheet.
• Capacitance & Voltage 10 µF nominal capacitance with tolerance −20% to +20% at a rated voltage of 50 V.
• Low loss (tan δ) Tangent of loss angle (tan δ) = 0.12 measured at 20 °C, 120 Hz.
• Low ESR & Ripple Performance ESR = 80 mΩ at 20 °C / 100 kHz; low-frequency ripple current 75 mA at 120 Hz and high-frequency ripple current 750 mA at 300 kHz.
• Leakage Current Specified leakage current: 100 µA (per product specification conditions).
• Temperature Range & Endurance Operating temperature −55 °C to 125 °C with a rated lifetime of 3000 hours at 125 °C.
• Package & Mounting Surface-mount radial can, dimensions φ6.3 × 5.8 mm; recommended land size 6.6 × 6.6 mm; supplied in embossed carrier taping and moisture-proof packing.
• Reflow Compatibility Compatible with lead-free reflow soldering conditions up to a 260 °C peak (per datasheet soldering profile).
• RoHS Compliant Meets RoHS directive requirements as noted in the datasheet.

Typical Applications

• Power rail decoupling Low ESR and high ripple current ratings make this capacitor suitable for smoothing and decoupling on DC power rails in high-frequency environments.
• DC–DC converter output filtering High-frequency ripple capability and compact SMD can packaging support output filtering in compact power modules.
• High-frequency power circuits The combination of low loss (tan δ) and low ESR supports use where high-frequency stability and reduced dissipation are required.

Unique Advantages

• High ripple tolerance: 750 mA at 300 kHz and 75 mA at 120 Hz enable sustained ripple handling across frequency ranges relevant to modern power converters.
• Low ESR performance: 80 mΩ at 100 kHz lowers voltage drop and heat generation, improving efficiency in power delivery and decoupling roles.
• Extended high-temperature life: Rated for 3000 hours at 125 °C, supporting designs that require long endurance under elevated operating temperatures.
• Compact SMD form factor: φ6.3 × 5.8 mm radial can footprint with a small recommended land pattern (6.6 × 6.6 mm) minimizes board area while keeping through-life performance.
• Lead-free reflow compatible: Specified soldering profile up to 260 °C peak simplifies integration into lead-free SMT manufacturing flows.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted-substance conformance.
