RKS1J100MCNAFGGS

The RKS1J100MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers a 10 µF capacitance at a 63 V rating in a compact φ6.3 × 7.7 mm can-style SMD package.

Designed for SMD power-bill-of-materials where high temperature endurance and low impedance matter, this part provides low ESR, high allowable ripple current, and a long load life up to 3000 hours at 125°C—making it suitable for demanding thermal and frequency environments.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance with a rated voltage of 63 V and capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low Loss (tan δ) — tanδ = 0.12 measured at 20°C, 120 Hz, supporting stable performance at rated conditions.
• Low ESR & High-Frequency Performance — ESR of 80 mΩ at 20°C/100 kHz and a high-frequency ripple current rating of 900 mA (at 300 kHz) for improved AC performance.
• Low-Frequency Ripple Handling — Rated low-frequency ripple current of 90 mA at 120 Hz for bulk and smoothing applications.
• Leakage Current — Leakage current specified at 100 µA, enabling predictable bias behavior after application of rated voltage.
• Extended High-Temperature Endurance — Rated life of 3000 hours at 125°C under rated voltage conditions.
• Compact SMD Can Package — φ6.3 × 7.7 mm package (L: 7.7 × D: 6.3 mm) with surface-mount land recommendation of 6.6 × 6.6 mm; packaged in embossed carrier tape with moisture-proof packing for automated assembly.
• Lead-free Reflow Compatibility — SMD construction supports lead-free reflow profiles up to a 260°C peak as described in the product series specification.
• Wide Operating Range — Specified operating temperature range from −55°C to +125°C.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• Power conversion and regulation — Bulk smoothing and decoupling in DC/DC converters and power rails where a 63 V rating and low ESR at high frequency are required.
• Point-of-load filtering — Local decoupling on high-density boards benefiting from compact SMD packaging and high-frequency ripple handling.
• High-temperature electronic assemblies — Deployments that need sustained performance up to 125°C and a 3000-hour load life at elevated temperature.

Unique Advantages

• Predictable high-temperature endurance — 3000 hours at 125°C provides a defined lifetime metric for thermal-stressed designs.
• High-frequency readiness — 80 mΩ ESR at 100 kHz combined with a 900 mA ripple current rating at 300 kHz supports effective high-frequency filtering.
• Compact SMD can format — φ6.3 × 7.7 mm package conserves board area while offering the performance of conductive polymer electrolytes.
• Controlled leakage behavior — Leakage current specified at 100 µA for predictable bias behavior after voltage application.
• Assembly-friendly packaging — Embossed carrier taping and moisture-proof packing simplify automated placement and reflow processes.
