RKS1K220MCNAHHGS

The RKS1K220MCNAHHGS is a Nichicon RKS-series conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It provides 22 µF capacitance at an 80 V rating with a compact φ8 × 8.7 mm form factor and is intended for general-purpose electronic applications that require low ESR, measurable high-frequency ripple capability and extended high-temperature endurance.

Designed for SMD assembly, this part combines low equivalent series resistance and high allowable ripple current with a 3000 hour load life at 125°C, offering a durable option for designs exposed to elevated operating temperatures and demanding ripple environments.

Key Features

• Core Technology Conductive polymer aluminum solid electrolytic construction for stable performance and conductive-film behavior.
• Electrical Performance 22 µF capacitance with ±20% tolerance and an 80 V rated voltage; dissipation factor (tanδ) 0.12 measured at 20°C, 120 Hz.
• Low ESR & High-Frequency Capability ESR of 40 mΩ at 20°C/100 kHz, supporting high-frequency decoupling and fast transient response.
• Ripple Current Performance Low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 1.1 A (300 kHz) to handle sustained AC stress.
• Leakage & Endurance Leakage current specified at 100 µA and rated life of 3000 hours at 125°C, enabling long-term operation under elevated temperature.
• Mechanical & Mounting Surface-mount radial can package, dimensions φ8 × 8.7 mm, supplied in embossed carrier taping with moisture-proof packing for automated placement.
• Environment & Compliance Operating temperature range –55°C to 125°C and RoHS compliant.

Typical Applications

• General-purpose electronic equipment Suitable where a compact, high-voltage SMD capacitor with extended life is required for general circuit smoothing and energy storage.
• High-frequency power circuits Low ESR at 100 kHz and a 1.1 A high-frequency ripple rating support applications with significant HF ripple demands.
• Elevated-temperature environments Rated life of 3000 hours at 125°C makes it suitable for assemblies exposed to sustained high operating temperatures.

Unique Advantages

• High ripple tolerance: Ripple current ratings of 110 mA (120 Hz) and 1.1 A (300 kHz) reduce stress on the capacitor under AC loading.
• Low ESR for efficient filtering: 40 mΩ ESR at 100 kHz helps minimize losses and improve voltage stability in high-frequency applications.
• Extended high-temperature endurance: 3000 hours at 125°C provides predictable longevity where elevated ambient temperatures are encountered.
• Compact SMD radial can: φ8 × 8.7 mm size in an SMD-compatible package simplifies board layout while delivering 80 V capability.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing supports automated placement and storage handling.
• Regulatory compliance: RoHS compliant construction for use in regulated assemblies.
