RKS1K120MCNAFGGS

The RKS1K120MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 12 µF capacitance at a rated voltage of 80 V in a compact SMD can (φ6.3 × 7.7 mm).

Designed for general-purpose surface-mount applications that require low ESR, high ripple capability and extended high-temperature endurance, this part combines high-frequency performance with a long rated life at elevated temperature.

Key Features

• Capacitance & tolerance — 12 µF with a tolerance of ±20% (–20%~20%) measured at 20°C, 120 Hz.
• Rated voltage — 80 V DC nominal rating for higher-voltage SMD applications.
• Low ESR — ESR of 80 mΩ measured at 20°C and 100 kHz, supporting lower loss and improved high-frequency performance.
• High ripple capability — Low-frequency ripple current 90 mA (120 Hz) and high-frequency ripple current 900 mA (300 kHz) for circuits with AC content.
• Leakage current — Specified leakage current of 100 µA after conditioning.
• Extended life at high temperature — Rated life of 3000 hours at 125°C under rated voltage.
• Wide operating temperature range — –55°C to 125°C for reliable operation across demanding thermal environments.
• SMD radial can package — Compact dimensions (φ6.3 × 7.7 mm) in a surface-mount can package suitable for automated assembly.
• Assembly-friendly packaging — Supplied in embossed carrier taping with moisture-proof packing for pick-and-place and storage.
• Lead-free reflow compatible — Designed to withstand lead-free reflow soldering conditions with a 260°C peak as described in the datasheet.
• RoHS compliant — Conforms to RoHS requirements.

Typical Applications

• General-purpose surface-mount circuits — Provides 12 µF/80 V capacitance in a compact SMD can for a variety of board-level designs classified as general purpose.
• High-frequency / high-ripple circuits — Low ESR (80 mΩ @100 kHz) and 900 mA high-frequency ripple rating support applications with significant AC ripple or switching noise.
• Elevated-temperature environments — Rated for operation from –55°C to 125°C with a 3000-hour life at 125°C for designs requiring sustained high-temperature endurance.

Unique Advantages

• High ripple tolerance: Specified low- and high-frequency ripple currents (90 mA @120 Hz, 900 mA @300 kHz) reduce the need to overspecify multiple parts for AC stress.
• Low-loss performance: 80 mΩ ESR at 100 kHz minimizes dissipation in high-frequency applications and supports cleaner power rails.
• Compact SMD footprint: φ6.3 × 7.7 mm radial can delivers 12 µF at 80 V in a small board area for space-constrained designs.
• Robust high-temperature life: 3000-hour endurance at 125°C under rated voltage provides proven longevity for demanding thermal conditions.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing simplifies automated placement and protects parts in storage.
• RoHS and lead-free reflow compatible: Meets RoHS and is specified for lead-free reflow profiles up to 260°C, aligning with modern assembly processes.
