RKS1J220MCNAFGGS

The RKS1J220MCNAFGGS is a surface-mount conductive-polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 22 µF capacitance at a 63 V rating in a compact radial can SMD package sized φ6.3 × 7.7 mm.

Engineered for high ripple-current and high-temperature endurance, this part supports lead‑free reflow soldering (peak 260°C) and is specified for operation across −55°C to 125°C with a rated load life of 3000 hours at 125°C.

Key Features

• Core Technology Conductive-polymer aluminum solid electrolyte construction for stable electrical characteristics in an SMD can package.
• Capacitance & Tolerance 22 µF nominal capacitance with tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low Loss (tan δ) tanδ = 0.12 specified at 20°C, 120 Hz, helping maintain performance in AC and ripple environments.
• Low ESR & High-Frequency Performance ESR 80 mΩ at 20°C/100 kHz and high-frequency ripple current rating of 900 mA (at 300 kHz), suited for high‑frequency decoupling and filtering.
• Low-Frequency Ripple & Leakage Low-frequency ripple current 90 mA (120 Hz) and leakage current specified at 100 µA aid predictable behavior in power applications.
• Thermal Endurance Operating range −55°C to 125°C with a rated life of 3000 hours at 125°C under rated voltage.
• Packaging & Assembly Surface-mount radial can (φ6.3 × 7.7 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead‑free reflow profiles up to 260°C.
• Regulatory RoHS compliant.

Typical Applications

• High-frequency filtering: Low ESR (80 mΩ at 100 kHz) and a 900 mA high-frequency ripple rating support filtering at switching frequencies and decoupling near power converters.
• Switch-mode power supplies: 63 V rating combined with 22 µF capacitance and robust ripple capability make it suitable for bulk or secondary-side smoothing in compact SMPS designs.
• Power-rail decoupling in compact SMD assemblies: Small φ6.3 × 7.7 mm can size and surface-mount packaging enable space-efficient placement close to regulators and ICs.
• High-temperature industrial electronics: Specified operation to 125°C and 3000-hour life at 125°C support applications that require elevated-temperature reliability.

Unique Advantages

• High ripple-current capability: 900 mA at 300 kHz and 90 mA at 120 Hz allow handling of both HF switching noise and lower-frequency ripple without undue heating.
• Predictable low ESR: 80 mΩ ESR at 100 kHz helps maintain tight voltage regulation and reduces loss in high-speed power circuits.
• Wide temperature range and extended life: −55°C to 125°C operating range and 3000 hours endurance at 125°C provide durable performance in demanding thermal environments.
• Reflow-compatible SMD form factor: Embossed carrier taping and tolerance of lead‑free reflow up to 260°C simplify automated assembly for modern SMT production.
• Controlled leakage and loss tangent: Leakage current specified at 100 µA and tanδ of 0.12 (20°C, 120 Hz) support predictable behavior in precision power applications.
