RKS1D820MCNAFGGS

The RKS1D820MCNAFGGS is a surface-mount conductive-polymer aluminum electrolytic capacitor from Nichicon's RKS series. It delivers 82 µF at 20 V in a compact SMD radial-can package sized φ6.3 × 7.7 mm, designed for applications that require low ESR and robust ripple-current handling.

Key value propositions include low equivalent series resistance (30 mΩ at 100 kHz), high-frequency ripple capability (1.4 A at 300 kHz), and extended endurance (3000 hours at 125°C), making it suitable for demanding power and high-frequency environments that require long-term stability and automated assembly.

Key Features

• Electrical Performance — 82 µF nominal capacitance with ±20% tolerance and tanδ 0.12 (measured at 20°C, 120 Hz) for predictable AC behavior.
• Low ESR & High-Frequency Support — ESR of 30 mΩ at 100 kHz and a high-frequency ripple current rating of 1.4 A at 300 kHz to support high-speed decoupling and filtering.
• Ripple Current Capability — 140 mA low-frequency ripple current at 120 Hz for bulk/filtering roles and 1.4 A at high frequency for switching environments.
• High Thermal Endurance — Rated operating range −55°C to +125°C with a load life of 3000 hours at 125°C, ensuring sustained performance under elevated temperatures.
• Surface-Mount Package & Assembly — Compact φ6.3 × 7.7 mm SMD radial-can package with surface mount land size 6.6 × 6.6 mm; supplied in embossed carrier tape with moisture-proof packing for automated pick-and-place.
• Leakage Current Control — Leakage current specified at 100 µA, measured after application of rated voltage per the datasheet conditioning method.
• Reflow Compatibility — Designed for lead‑free reflow soldering with peak temperature allowance up to 260°C as defined in the datasheet’s soldering profile.
• Regulatory Status — RoHS compliant.

Typical Applications

• High‑frequency power filtering — Use where low ESR (30 mΩ at 100 kHz) and 1.4 A high-frequency ripple handling are required for effective HF decoupling.
• High-temperature electronic assemblies — Suitable for circuits operating across −55°C to 125°C with long life at elevated temperature (3000 hours at 125°C).
• Compact SMD power modules — Small φ6.3 × 7.7 mm radial-can package provides 82 µF capacitance in space-constrained designs requiring surface-mount assembly.
• Automated production lines — Embossed carrier tape and moisture-proof packing support high-volume pick-and-place and reflow processes up to 260°C.

Unique Advantages

• Low ESR for efficient filtering: 30 mΩ at 100 kHz minimizes voltage ripple and heat dissipation in high-frequency circuits.
• High ripple-current tolerance: 1.4 A at 300 kHz and 140 mA at 120 Hz accommodate both switching and low-frequency ripple stresses.
• Extended high-temperature life: 3000 hours at 125°C provides predictable long-term performance in hot operating environments.
• SMD-ready form factor: Compact radial-can SMD size and embossed tape packaging simplify integration into automated assembly workflows.
• Lead-free reflow capable: Compatibility with peak reflow temperatures up to 260°C aligns with modern lead-free SMT processes.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
