RKS1J8R2MCNAFEGS

The RKS1J8R2MCNAFEGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 8.2 µF capacitance at a 63 V rating. Designed for applications that demand low ESR and high allowable ripple current, this SMD can supports elevated operating temperatures and extended endurance.

This part is optimized for compact power circuits where stable capacitance, high-frequency performance and robust thermal endurance (–55 °C to 125 °C) are required.

Key Features

• Capacitance and Voltage — 8.2 µF capacitance with a 63 V rated voltage and ±20% tolerance at 20 °C, 120 Hz.
• Low ESR and Ripple Handling — ESR of 120 mΩ measured at 20 °C/100 kHz, with specified ripple current of 70 mA at 120 Hz (low frequency) and 700 mA at 300 kHz (high frequency).
• Thermal and Endurance Performance — Rated operating temperature range from −55 °C to 125 °C and a rated life of 3000 hours at 125 °C under rated voltage.
• Leakage and Loss — Leakage current specified at 100 µA (or 0.05CV if greater) after 2 minutes at rated voltage; tangent of loss angle (tan δ) ≤ 0.12 at 20 °C, 120 Hz.
• SMD Package and Mounting — Compact radial can SMD package sized φ6.3 × 5.8 mm (L × D) with surface-mount land size 6.6 × 6.6 mm; supplied in embossed carrier taping with moisture-proof packing for automated placement.
• Reflow Compatibility — Supports lead-free reflow soldering with peak temperatures up to 260 °C as described in the series datasheet.
• RoHS Compliance — Compliant with RoHS requirements as stated in the product data.

Typical Applications

• Power-supply decoupling and bulk filtering — Low ESR and high allowable ripple current make the capacitor suitable for smoothing and decoupling in compact power rails.
• DC–DC converter output filtering — High-frequency ripple current capability and low loss angle help maintain stable output voltage in switching power stages.
• High-temperature electronics — Rated life of 3000 hours at 125 °C and wide operating range (−55 °C to 125 °C) support use in thermally demanding assemblies.

Unique Advantages

• High ripple capability: Specified ripple currents of 70 mA (120 Hz) and 700 mA (300 kHz) support both low- and high-frequency ripple environments.
• Low ESR at high frequency: 120 mΩ ESR at 100 kHz reduces loss and heat generation in high-frequency circuits.
• Extended high-temperature life: 3000-hour endurance at 125 °C provides design margin for long-term reliability in hot environments.
• Compact SMD form factor: φ6.3 × 5.8 mm package and embossed carrier taping streamline automated assembly in space-constrained designs.
• Reflow-capable: Designed for lead-free reflow profiles up to 260 °C, simplifying assembly in modern SMT processes.
• RoHS compliant: Conforms to RoHS directives for use in regulated supply chains.
