RKS1H220MCNAHFGS

The RKS1H220MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 22 µF capacitance at a 50 V rating in a compact φ8 × 6.7 mm SMD can optimized for high ripple current and extended high-temperature operation.

Engineered for demanding power applications, this device combines low ESR, high allowable ripple current, and a long endurance (3000 hours at 125°C) to support robust smoothing and decoupling in compact assemblies.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 50 V.
• Low ESR & High Ripple Capability — ESR specified at 30 mΩ (20°C, 100 kHz) with rated ripple currents of 160 mA at 120 Hz and 1.6 A at 300 kHz, enabling efficient high-frequency power handling.
• High-Temperature Endurance — Rated for 3000 hours at 125°C under rated voltage, supporting long-term operation in elevated-temperature environments.
• Wide Operating Range — Operating temperature range from −55°C to +125°C provides broad thermal headroom for industrial and high-temperature electronics.
• Loss Characteristics & Leakage — Tangent of loss angle (tanδ) of 0.12 at 20°C/120 Hz and leakage current specified at 100 µA for predictable behavior in bias conditions.
• SMD Can Package & Handling — Radial can SMD (φ8 × 6.7 mm) with surface mount land recommendation of 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing for automated placement and storage.
• Reflow Compatibility — Designed for lead‑free reflow soldering (260°C peak) per the series soldering recommendations.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• Power supply filtering and decoupling — Low ESR and high ripple current capability (1.6 A at 300 kHz) make this capacitor suitable for smoothing and decoupling in switching power stages.
• High-frequency power modules — Compact SMD can and rated performance at 100 kHz support use in compact DC–DC converters and high-frequency power circuits.
• Industrial electronics operating at elevated temperatures — 3000-hour endurance at 125°C and −55°C to +125°C operating range provide reliability in thermally demanding installations.

Unique Advantages

• High ripple tolerance in a compact SMD can — Combines 1.6 A high-frequency ripple rating with a φ8 × 6.7 mm package to reduce board area without sacrificing power-handling capability.
• Predictable AC and DC performance — Specified tanδ, ESR, and leakage current values allow straightforward margin calculations for power‑stage design.
• Designed for high-temperature longevity — 3000 hours at 125°C endurance rating supports long service life in elevated-temperature applications.
• Manufacturing-ready packaging — Embossed carrier tape with moisture-proof packing simplifies automated placement and storage for volume production.
• Reflow-process compatibility — Rated for lead‑free reflow to 260°C, enabling integration into modern Pb‑free assembly flows.
