RKS1J220MCNAHJGS

The RKS1J220MCNAHJGS 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 φ8 × 10 mm can-style SMD package, targeted for general-purpose electronic applications.

Designed for demanding operating conditions, this part combines low ESR and high allowable ripple current with a wide operating temperature range (−55 °C to 125 °C) and a rated load life of 3000 hours at 125 °C, making it suitable where stable filtering and long-term endurance are required.

Key Features

• Capacitance & Voltage — 22 µF rated capacitance with a 63 V working voltage and a tolerance of −20% to +20% at 20 °C, 120 Hz.
• Conductive Polymer Dielectric — Solid conductive polymer construction for stable electrical characteristics under load.
• Low ESR — ESR of 40 mΩ measured at 100 kHz and 20 °C, enabling efficient high-frequency performance.
• High Allowable Ripple Current — Low-frequency ripple current of 110 mA (120 Hz) and high-frequency ripple current of 1.1 A (300 kHz) for effective smoothing and decoupling at multiple frequencies.
• Wide Temperature & Endurance — Operating temperature range from −55 °C to 125 °C with a rated life of 3000 hours at 125 °C.
• Electrical Losses — Tangent of loss angle (tan δ) specified at 0.12 (measured at 20 °C, 120 Hz), supporting predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 100 µA (or per datasheet conditioning rules), suitable for many power-management applications.
• Package & Handling — φ8 × 10 mm radial can SMD package supplied in embossed carrier taping with moisture-proof packing for automated assembly and storage.
• Compliance — RoHS compliant.

Typical Applications

• General Purpose Electronics — Surface-mount designs that require reliable bulk capacitance and stable performance across a broad temperature range.
• Power Supply Filtering — Filtering and decoupling where low ESR (40 mΩ) and high-frequency ripple handling (1.1 A at 300 kHz) improve regulation and transient response.
• High-Temperature Environments — Applications requiring endurance at elevated temperatures, supported by a 3000-hour rating at 125 °C.

Unique Advantages

• Low-loss performance: 40 mΩ ESR at 100 kHz combined with tan δ = 0.12 yields predictable high-frequency behavior for decoupling and filtering.
• High ripple capability: Rated for 1.1 A at 300 kHz (high frequency) and 110 mA at 120 Hz (low frequency), enabling dual-frequency filtering strategies.
• Robust thermal endurance: −55 °C to 125 °C operating range with 3000 hours life at 125 °C supports designs exposed to elevated temperatures.
• Compact SMD can package: φ8 × 10 mm radial can SMD fits space-constrained boards while supporting automated embossed carrier taping and moisture-proof packing.
• Predictable leakage: Specified leakage current of 100 µA helps designers budget standby and quiescent currents.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
