RKS1D680MCNAFGGS

The RKS1D680MCNAFGGS is a Nichicon RKS series conductive polymer aluminum solid electrolytic capacitor in a compact surface‑mount can. It delivers 68 µF capacitance at a 20 V rating with low ESR and specified ripple current performance.

Engineered for compact SMD power designs, the part provides high-frequency ripple handling, wide operating temperature range (−55 °C to 125 °C) and a long endurance rating (3000 hours at 125 °C), making it suitable for high‑stress, high‑temperature electronics assemblies.

Key Features

• Capacitance & Voltage: 68 µF nominal capacitance with a rated voltage of 20 V and tolerance of −20% to +20% at 20 °C, 120 Hz.
• Low ESR: Equivalent series resistance of 30 mΩ measured at 20 °C, 100 kHz to minimize loss and voltage drop under AC conditions.
• High ripple capability: Low‑frequency ripple current 140 mA (120 Hz) and high‑frequency ripple current 1.4 A (300 kHz) for demanding power‑stage applications.
• Leakage & dissipation: Leakage current specified at 100 µA and tanδ (loss tangent) of 0.12 at 20 °C, 120 Hz.
• Thermal endurance: Rated operating temperature from −55 °C to 125 °C with a rated life of 3000 hours at 125 °C.
• Reflow and assembly compatibility: SMD can package designed for lead‑free reflow soldering with peak temperatures up to 260 °C (reflow profile per datasheet guidance).
• Compact SMD package: Case size φ6.3 × 7.7 mm (L × D); surface‑mount land recommendation L: 6.6 mm × W: 6.6 mm; supplied in embossed carrier taping with moisture proof packing.
• RoHS compliant: Meets RoHS directive requirements as specified in the product documentation.

Typical Applications

• Power conversion and DC‑DC output filtering: Low ESR (30 mΩ) and 1.4 A high‑frequency ripple rating support smoothing and energy storage in compact power stages.
• High‑frequency power paths: High allowable ripple current at 300 kHz makes the capacitor suitable for high‑speed switching environments where HF ripple suppression is required.
• High‑temperature electronics: Specified life of 3000 hours at 125 °C and an operating range to −55 °C supports use in elevated‑temperature assemblies and industrial applications.
• SMD compact assemblies: Small φ6.3 × 7.7 mm SMD can and embossed carrier taping enable automated placement in dense board layouts.

Unique Advantages

• High ripple handling in a small package: 1.4 A at 300 kHz combined with 68 µF capacitance gives high dynamic performance without large board area.
• Low ESR for efficient power delivery: 30 mΩ ESR at 100 kHz reduces power loss and heat generation in high‑frequency circuits.
• Long high‑temperature life: 3000‑hour endurance at 125 °C provides predictable life performance for thermally demanding designs.
• Reflow compatible SMD form factor: Designed for lead‑free reflow processes (peak up to 260 °C) and supplied in embossed carrier tape for production assembly.
• Controlled leakage and dissipation: Leakage current (100 µA) and tanδ (0.12) are specified to help designers assess standby losses and dissipation budgets.
• Regulatory compliance: RoHS compliance supports integration into designs targeting current environmental requirements.
