RKS1V220MCNAHJGS

The RKS1V220MCNAHJGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series, rated 22 µF at 35 V. Designed for general-purpose SMD applications, it delivers low equivalent series resistance and high allowable ripple current in a compact φ8 × 10 mm can package.

Key value propositions include low ESR (27 mΩ at 100 kHz), high-frequency ripple capability (1.6 A at 300 kHz), and extended endurance (3000 hours at 125°C), making it suitable for demanding power and decoupling roles in compact assemblies.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic construction from the RKS series, offering the electrical characteristics of polymer electrolytes in an SMD can format.
• Electrical Characteristics 22 µF rated capacitance at 35 V with tolerance of -20% to +20%; tangent of loss angle (tan δ) specified at 0.12 (measured at 20°C, 120 Hz).
• Low ESR and High Ripple Capability ESR of 27 mΩ measured at 20°C/100 kHz, low-frequency ripple current 160 mA at 120 Hz, and high-frequency ripple current 1.6 A at 300 kHz support stable operation under dynamic load.
• Leakage and Polarization Polarized design with leakage current specified at 100 µA (per product specification conditions).
• Reliability and Endurance Rated life of 3000 hours at 125°C; meets endurance and damp‑heat criteria defined for the RKS series.
• Package and Handling Surface-mount radial can (φ8 × 10 mm) supplied in embossed carrier taping with moisture-proof packing for automated assembly and storage.
• Operating Range Wide operating temperature range from -55°C to +125°C as specified for the series.
• RoHS Compliance The RKS series is described as compliant with the RoHS directive (2011/65/EU, (EU)2015/863) in the series datasheet.

Typical Applications

• General-purpose surface-mount circuits Compact SMD power and signal boards that require a 22 µF, 35 V polymer aluminum capacitor with low ESR and measurable ripple capability.
• Power supply filtering Filtering and smoothing in DC power rails where the specified ripple current handling and low ESR contribute to stable voltage performance.
• High-frequency decoupling Decoupling in circuits operating at higher frequencies, taking advantage of the 27 mΩ ESR at 100 kHz and the 1.6 A high-frequency ripple spec.

Unique Advantages

• Low ESR for improved dynamic performance: 27 mΩ at 100 kHz reduces voltage drop and heating under AC stress, improving stability in high-frequency environments.
• High ripple current tolerance: Specified 160 mA (120 Hz) and 1.6 A (300 kHz) ratings help manage thermal rise and extend service life in ripple‑heavy applications.
• High-temperature endurance: 3000 hours at 125°C provides long-term reliability for designs exposed to elevated operating temperatures.
• SMD-friendly packaging: φ8 × 10 mm radial can in embossed carrier tape with moisture-proof packing supports automated pick-and-place and controlled storage.
• Stable loss characteristics: tan δ of 0.12 (20°C, 120 Hz) provides predictable AC loss behavior for circuit designers.
• RoHS-aligned series: Series-level compliance with RoHS directives simplifies regulatory considerations for many markets.
