RKS1K220MCNAHJGS

The RKS1K220MCNAHJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon's RKS series. It provides 22 µF capacitance at an 80 V rating in a compact radial can SMD package with embossed carrier taping and moisture-proof packing.

Designed for general-purpose power applications, the part combines low ESR and high allowable ripple current with extended endurance—3000 hours at 125°C—making it suitable for demanding board-level power filtering and decoupling where wide temperature range and reliable long-term operation are required.

Key Features

• Dielectric and construction  Conductive polymer aluminum solid electrolyte construction for stable performance in surface-mount implementations.
• Capacitance & voltage  22 µF capacitance with tolerance -20%~20% and rated voltage of 80 V.
• Low loss and leakage  tanδ of 0.12 (measured at 20°C, 120 Hz) and leakage current specified at 100 µA.
• Low ESR and ripple handling  ESR of 40 mΩ at 20°C/100 kHz with ripple current ratings of 110 mA (120 Hz) and 1.1 A (300 kHz).
• Extended endurance  Load life of 3000 hours at 125°C per series specification.
• Wide operating temperature  Rated for –55°C to +125°C operation.
• SMD package and assembly  Radial can SMD package (φ8×10L / L:1×D:0.8 cm) supplied in embossed carrier tape with moisture-proof packing; compatible with lead-free reflow conditions up to a 260°C peak per datasheet.
• RoHS compliant  Meets RoHS directive requirements as indicated in product documentation.

Typical Applications

• Power supply filtering and decoupling  General-purpose board-level filtering where a 22 µF, 80 V capacitor with low ESR provides bulk decoupling and smoothing.
• High-frequency smoothing  Use in circuits requiring high-frequency ripple handling, leveraging 40 mΩ ESR at 100 kHz and a 1.1 A high-frequency ripple rating.
• SMD assemblies with automated placement  Surface-mount radial can in embossed carrier tape simplifies pick-and-place and reflow assembly processes.
• Elevated-temperature applications  Suitable for designs that demand operation across –55°C to 125°C and extended life at high temperature (3000 h at 125°C).

Unique Advantages

• Low ESR for improved transient response: 40 mΩ ESR at 100 kHz reduces voltage drop and supports faster transient handling in power circuits.
• High allowable ripple current: Rated ripple currents of 110 mA (120 Hz) and 1.1 A (300 kHz) enable reliable filtering across frequency ranges.
• Long high-temperature life: 3000 hours endurance at 125°C provides predictable lifetime performance for thermally demanding designs.
• Wide operating temperature range: –55°C to +125°C rating supports use across varied thermal environments.
• Manufacturing-ready packaging: Embossed carrier taping and moisture-proof packing with compatibility for lead-free reflow (260°C peak) streamline board assembly.
• Controlled leakage and dissipation: Leakage current specified at 100 µA and tanδ of 0.12 help maintain efficiency and predictable loss characteristics.
