RKS1C680MCNAFGGS

The RKS1C680MCNAFGGS from Nichicon is a surface-mount conductive polymer aluminum electrolytic capacitor rated at 68 µF and 16 V. It combines low ESR and high allowable ripple current in a compact SMD radial can package (φ6.3 × 7.7 mm), targeting general-purpose power applications that require reliable decoupling and energy storage in compact assemblies.

Designed for demanding thermal environments, this part supports an operating temperature range of −55°C to +125°C and a rated lifetime of 3000 hours at 125°C, delivering stable capacitance and leakage behavior over extended high-temperature use.

Key Features

• Capacitance & Voltage — 68 µF capacitance with a rated voltage of 16 V and tolerance of −20% to +20% at 120 Hz, 20°C.
• Conductive Polymer Electrolyte — Solid polymer construction provides stable performance with low leakage current (100 µA specified) after voltage application.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ measured at 20°C/100 kHz and high-frequency ripple current capability of 1.5 A at 300 kHz for improved power integrity at switching frequencies.
• Ripple Current Rating — 150 mA at 120 Hz (low frequency) and 1.5 A at 300 kHz (high frequency) to handle a range of power-supply ripple conditions.
• Wide Temperature & Long Life — Operating temperature range −55°C to +125°C with a rated endurance of 3000 hours at 125°C.
• Surface-Mount Radial Can Package — Compact φ6.3 × 7.7 mm SMD can with embossed carrier taping and moisture-proof packing for automated assembly.

Typical Applications

• General-purpose SMD power circuits — Suited for surface-mount power decoupling and bulk storage where a polarized, compact capacitor with 68 µF/16 V is required.
• Switching power supplies and converters — Low ESR (30 mΩ at 100 kHz) and 1.5 A high-frequency ripple current rating support smoothing and stability at switching frequencies.
• High-temperature electronics — Use in applications that must tolerate sustained elevated temperatures, leveraging the −55°C to +125°C range and 3000-hour life at 125°C.

Unique Advantages

• High ripple-handling capability — 1.5 A at 300 kHz supports demanding high-frequency power rails and reduces stress on upstream circuitry.
• Low equivalent series resistance — 30 mΩ ESR at 100 kHz improves transient response and reduces heat generation under ripple conditions.
• Robust elevated-temperature life — 3000 hours at 125°C provides predictable endurance for long-term use in hot environments.
• Compact SMD form factor — φ6.3 × 7.7 mm radial can in embossed carrier taping enables automated placement in space-constrained designs.
• Stable leakage and loss characteristics — Leakage current specified at 100 µA and tanδ of 0.12 (20°C, 120 Hz) for reliable performance after voltage application.
