RKS1E100MCNAFEGS

The RKS1E100MCNAFEGS is a surface-mount conductive polymer aluminum electrolytic capacitor rated 10 µF at 25 V. It delivers low equivalent series resistance and high allowable ripple current in a compact SMD can (φ6.3 × 5.8 mm) for reliable power decoupling and high-frequency filtering.

Designed for high-temperature operation and automated assembly, the part is specified for −55 °C to 125 °C, a load life of 3000 hours at 125 °C, and is supplied in embossed carrier taping with moisture-proof packing for mass-production use.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance with tolerance −20% to +20% at a rated voltage of 25 V.
• Low-loss Dielectric — tanδ (DF) = 0.12 measured at 20 °C, 120 Hz, providing predictable AC performance.
• Low ESR & High-Frequency Performance — ESR 50 mΩ measured at 20 °C/100 kHz and a high-frequency ripple current rating of 900 mA at 300 kHz for effective high-speed decoupling.
• Ripple & Leakage — Low-frequency ripple current 90 mA at 120 Hz and maximum leakage current 100 µA.
• High-Temperature Endurance — Operating range −55 °C to 125 °C with rated life/endurance of 3000 hours at 125 °C.
• Assembly-Ready Package — Surface-mount radial can (SMD) in size φ6.3 × 5.8 mm; compatible with lead-free reflow profiles up to 260 °C as specified for the series.
• Production-Friendly Packaging — Embossed carrier taping and moisture-proof packing for automated placement and storage.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Power-rail decoupling — Provides bulk and high-frequency decoupling on DC power rails where low ESR and compact SMD mounting are required.
• High-frequency filtering — Suited for smoothing high-frequency ripple in switching environments thanks to 900 mA @ 300 kHz capability and 50 mΩ ESR.
• High-temperature electronics — Component choice for assemblies that must withstand sustained elevated temperatures up to 125 °C and a 3000-hour rated life.
• Compact SMD power assemblies — Small can footprint and reflow-capable construction simplify integration into space-constrained, automated production lines.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 90 mA (120 Hz) and 900 mA (300 kHz) enable robust handling of both low- and high-frequency ripple components.
• Low ESR: 50 mΩ at 100 kHz reduces conduction loss and voltage drop under dynamic load, improving regulator stability and thermal behavior.
• Extended high-temperature life: 3000 hours endurance at 125 °C supports reliable long-term operation in elevated-temperature environments.
• Conductive polymer construction: Series specification highlights low LC and high allowable ripple current, delivering consistent AC performance in SMD form.
• Reflow- and production-ready: Lead-free reflow compatibility and embossed carrier taping with moisture-proof packing streamline pick-and-place assembly and storage.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for assembled products.
