RKS1C680MCNAHGGS

The RKS1C680MCNAHGGS is a surface-mount conductive polymer aluminum electrolytic capacitor in Nichicon’s RKS series, offering 68 µF capacitance at a 16 V rating. It combines low ESR and high allowable ripple current with an extended load life to support demanding power-decoupling and filtering tasks.

Designed for general-purpose electronics, this SMD radial-can part delivers a compact 8 mm diameter × 7.7 mm length footprint, embossed carrier taping with moisture-proof packing, and mass-production availability for volume designs.

Key Features

• Conductive polymer aluminum construction — Solid electrolytic design for stable capacitance and performance in SMD radial-can form.
• Capacitance & tolerance — 68 µF with tolerance of −20% to +20% at 20°C, 120 Hz, suitable for general-purpose decoupling and bulk storage.
• Rated voltage — 16 V DC rating for mid-voltage rail applications.
• Low ESR and high-frequency performance — ESR of 30 mΩ measured at 20°C/100 kHz, enabling effective high-frequency filtering.
• High allowable ripple current — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) to handle AC ripple on power rails.
• Wide temperature range and long life — Operates from −55°C to +125°C with a rated load life of 3000 hours at 125°C.
• Leakage current — Specified leakage current of 100 µA for stable standby performance.
• Assembly and packaging — Surface-mount radial, can-style package supplied in embossed carrier taping with moisture-proof packing for automated placement.
• RoHS compliance and reflow compatibility — Series-level datasheet indicates RoHS directive compliance and lead-free reflow soldering conditions up to a 260°C peak.

Typical Applications

• Power supply decoupling — Low ESR and high ripple current capability make it suitable for local decoupling on intermediate and low-voltage rails.
• High-frequency filtering — ESR measured at 100 kHz and 1.6 A ripple rating at 300 kHz support broadband EMI/RFI and switching-noise attenuation.
• Industrial and general electronics — Extended temperature range (−55°C to +125°C) and 3000-hour life at 125°C suit long-lived, thermally demanding systems.
• Compact SMD designs — Radial can SMD package (φ8 × 7.7 mm) for space-constrained PCBs requiring higher capacitance than typical MLCCs.

Unique Advantages

• Stable high-frequency behavior — 30 mΩ ESR at 100 kHz provides reliable performance for switching regulators and high-speed decoupling.
• High ripple handling — 1.6 A ripple current at 300 kHz reduces temperature rise and extends service life under AC stress.
• Extended thermal endurance — 3000 hours rated life at 125°C enables deployment in elevated-temperature environments with predictable aging.
• Compact, production-ready packaging — Embossed carrier taping with moisture-proof packing supports automated assembly and inventory handling.
• Clear leakage specification — Defined maximum leakage current of 100 µA simplifies end-of-line validation for standby and bias circuits.
• RoHS and lead-free reflow compatibility — Series-level compliance and reflow profiles support modern manufacturing and environmental requirements.
