RKS1K100MCNAHFGS

The RKS1K100MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the Nichicon RKS series. It provides 10 µF capacitance at an 80 V rating with a polarized SMD radial can package and is offered in embossed carrier taping with moisture-proof packing.

Designed for general-purpose power circuits that require low ESR and high ripple capability, this part delivers targeted performance for high-frequency decoupling, smoothing and applications operating across a wide temperature range up to 125°C with a rated load life of 3000 hours at 125°C.

Key Features

• Capacitance & Voltage — 10 µF capacitance rated for 80 V operation with a tolerance of -20% to +20%.
• Conductive Polymer Electrolyte — Solid polymer construction for stable performance and predictable leakage behavior (100 µA specified).
• Low ESR & High-Frequency Performance — ESR of 40 mΩ measured at 20°C/100 kHz, enabling effective high-frequency ripple handling and decoupling.
• High Allowable Ripple Current — Rated ripple current of 110 mA at 120 Hz (low frequency) and 1.1 A at 300 kHz (high frequency) for demanding power applications.
• Extended High-Temperature Endurance — Load life rated to 3000 hours at 125°C, supporting long-term operation in elevated-temperature environments.
• Wide Operating Temperature — Specified from -55°C to 125°C for broad environmental tolerance.
• Compact SMD Package — Radial can, SMD form factor with size D: 8 mm × L: 6.7 mm, supplied in embossed carrier taping and moisture-proof packing for assembly.
• RoHS Compliant — Meets RoHS requirements as indicated in the product data.

Typical Applications

• Power supply decoupling — Low ESR and high ripple capability make the capacitor suitable for smoothing and local decoupling in regulated and switching power supplies.
• High-frequency filtering — Specified ESR at 100 kHz and high-frequency ripple current rating support filtering at elevated switching frequencies.
• Industrial electronics — Long life at 125°C and wide operating temperature range suit control and power modules exposed to elevated temperatures.

Unique Advantages

• High ripple tolerance: The combination of low ESR (40 mΩ) and a 1.1 A high-frequency ripple rating reduces thermal stress and improves performance in switching environments.
• Extended thermal endurance: 3000 hours at 125°C provides predictable lifetime behavior for designs requiring elevated-temperature operation.
• Solid polymer reliability: Conductive polymer electrolyte gives controlled leakage (100 µA specified) and stable electrical characteristics over temperature.
• SMD-ready packaging: Radial can SMD form and embossed carrier taping with moisture-proof packing streamline pick-and-place assembly and supply-chain handling.
• Compact footprint: φ8 × 6.7 mm package size enables space-efficient placement for board-level power conditioning.
