RKS1V680MCNAHFGS

The RKS1V680MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RKS series. It delivers 68 µF at 35 V in a compact φ8 × 6.7 mm can-style SMD package designed for applications that require low ESR, high ripple handling, and extended life at elevated temperatures.

This capacitor is optimized for high-frequency and high-ripple environments, offering a combination of low ESR (30 mΩ at 100 kHz), high allowable ripple current (1.6 A at 300 kHz), and rated endurance of 3000 hours at 125°C — making it suitable for demanding industrial and power-conversion electronics.

Key Features

• Capacitance & Tolerance: 68 µF nominal capacitance with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage: 35 V working voltage suitable for many board-level power rail applications.
• Low ESR: 30 mΩ ESR measured at 20°C and 100 kHz, supporting efficient high-frequency decoupling and reduced dissipation.
• High Ripple Capability: 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) allowable ripple current for use in switching regulators and point-of-load stages.
• Thermal Endurance: Rated operating temperature range from -55°C to +125°C with a rated life of 3000 hours at 125°C for long-term stability under thermal stress.
• Soldering & Mounting: Surface-mount, radial can SMD package with compatibility for lead-free reflow (260°C peak per datasheet reflow guidelines); supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Leakage & Loss: Specified leakage current ~119 µA and tan δ of 0.12 (20°C, 120 Hz), enabling predictable leakage and dissipation behavior in circuits.
• Compliance: RoHS compliant as specified in the product data.

Typical Applications

• DC-DC converter output filtering: Low ESR and high ripple current capability make it suitable for smoothing and bulk decoupling on converter outputs and synchronous regulator stages.
• Point-of-load decoupling: Compact SMD can package and strong high-frequency performance support local decoupling near power ICs in industrial and communications equipment.
• Industrial power electronics: Extended 3000-hour life at 125°C and a -55°C to 125°C operating range support use in high-temperature power modules and control electronics.
• Networking and telecom power subsystems: Low ESR and stable high-frequency ripple handling help maintain clean rails for line cards, power supplies, and other high-demand subsystems.

Unique Advantages

• High ripple tolerance: 1.6 A at 300 kHz and 160 mA at 120 Hz capability reduces heating and improves reliability in switching applications.
• Low dissipation losses: 30 mΩ ESR at 100 kHz lowers I²R losses and helps maintain efficiency in power conversion circuits.
• Extended high-temperature life: 3000 hours at 125°C provides predictable longevity in elevated-temperature environments.
• Compact SMD design: φ8 × 6.7 mm package and defined PCB land pattern (8.3 × 8.3 mm) enable dense board layouts while maintaining robust performance.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing supports automated pick-and-place and reflow processes.
• Measured electrical stability: Specified tan δ (0.12 at 20°C/120 Hz) and defined leakage current facilitate predictable circuit design and margining.
