RKS1K680MCNAJLGS

The RKS1K680MCNAJLGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in an SMD can package, offered as part of the RKS series. It provides 68 µF capacitance at an 80 V rated voltage with a wide operating temperature range of –55°C to 125°C.

Designed for general-purpose electronics requiring high allowable ripple current, low ESR and robust high-temperature endurance, this surface-mount capacitor is targeted at applications where stability and long life at elevated temperature are required.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance with an 80 V rated voltage and capacitance tolerance of ±20% (–20% to +20%).
• Conductive Polymer Solid Electrolyte — Solid polymer construction for stable electrical characteristics and improved ripple handling compared with conventional electrolytes.
• Low ESR & High-Frequency Performance — ESR of 30 mΩ measured at 20°C/100 kHz and a high-frequency ripple current rating of 1.4 A (300 kHz), supporting demanding decoupling and filtering tasks.
• Low-Frequency Ripple & Loss — Low-frequency ripple current of 140 mA at 120 Hz and tanδ (DF) of 0.12 at 20°C/120 Hz for predictable low-frequency behavior.
• High-Temperature Endurance — Rated life of 3000 hours at 125°C, enabling use in high-temperature environments.
• Surface-Mount Package — Radial can SMD package, size φ10 × 12.4 mm, supplied in embossed carrier taping with moisture-proof packing for automated placement.
• Leakage Current — Specified leakage current of 272 µA, supporting predictable bias performance after voltage application.
• Compliance — RoHS compliant.

Typical Applications

• General-purpose electronics — Suited for designs that call out a compact, high-voltage SMD capacitor with solid polymer construction.
• High-temperature designs — Applicable where component endurance at elevated temperatures (up to 125°C) is required.
• High-ripple SMD circuits — Well suited to surface-mount board locations that must handle elevated ripple currents and low ESR demands.

Unique Advantages

• High voltage in a compact SMD can: 80 V rating combined with a φ10 × 12.4 mm SMD package delivers high-voltage capability in a space-efficient form factor.
• Solid polymer construction for stability: Conductive polymer electrolyte provides consistent electrical characteristics and supports high allowable ripple currents.
• Low ESR for improved transient response: 30 mΩ ESR at 100 kHz reduces losses and improves high-frequency decoupling performance.
• Designed for elevated-temperature service: 3000 hours endurance at 125°C provides long-term reliability in hot operating environments.
• Production-ready packaging: Embossed carrier taping with moisture-proof packing facilitates automated assembly and storage.
• Measurable low-frequency behavior: 140 mA ripple at 120 Hz and tanδ of 0.12 at 20°C/120 Hz for predictable low-frequency performance.
