RKS1V220MCNAFGGS

The RKS1V220MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon's RKS series. It delivers 22 µF capacitance at 35 V with low equivalent series resistance and high allowable ripple current for demanding power applications.

Designed for high-temperature operation, the device is rated for –55 °C to 125 °C and provides a rated life of 3000 hours at 125 °C. The SMD package (φ6.3 × 7.7 mm) is supplied in embossed carrier taping with moisture-proof packing for automated assembly.

Key Features

• Core Electricals — 22 µF capacitance at 35 V with capacitance tolerance of −20% to +20% (120 Hz, 20 °C).
• Low Loss & Low ESR — tanδ (DF) = 0.12 (20 °C, 120 Hz) and ESR = 35 mΩ measured at 20 °C / 100 kHz, supporting efficient high-frequency decoupling.
• High Ripple Handling — Low-frequency ripple current 140 mA (120 Hz) and high-frequency ripple current 1.4 A (300 kHz) for switching power applications.
• Leakage Current — Specified leakage current up to 100 µA after rated voltage application.
• High-Temperature Endurance — Load life rated 3000 hours at 125 °C; meets endurance and damp-heat performance criteria in the RKS series datasheet.
• Reflow-Compatible SMD — Surface-mount radial can (SMD) package sized φ6.3 × 7.7 mm; compatible with lead-free reflow profiles up to 260 °C as specified for the series.
• Assembly-Ready Packaging — Supplied in embossed carrier taping with moisture-proof packing for automated pick-and-place lines.
• Regulatory — RoHS compliant as specified for the series.

Typical Applications

• Power supply input/output filtering — Low ESR and high ripple-current capability make this part suitable for smoothing and decoupling on 35 V rails.
• DC–DC converter outputs — High-frequency ripple rating (1.4 A at 300 kHz) and 35 mΩ ESR support switching regulator stability and transient response.
• Industrial and high-temperature electronics — Rated operation to 125 °C and 3000-hour life at 125 °C address reliability demands in elevated-temperature environments.
• Compact SMD power modules — Small φ6.3 × 7.7 mm SMD can and embossed tape packaging simplify integration into compact, automated assemblies.

Unique Advantages

• Extended high-temperature life: 3000 hours at 125 °C provides predictable long-term performance in elevated-temperature deployments.
• High-frequency performance: 35 mΩ ESR at 100 kHz and low tanδ support low-loss operation and effective HF decoupling.
• Robust ripple handling: 1.4 A high-frequency ripple current rating addresses the needs of modern switching power stages.
• SMD-ready form factor: φ6.3 × 7.7 mm can in embossed carrier taping with moisture-proof packing streamlines automated assembly and inventory handling.
• Predictable leakage and tolerance: Specified leakage current (100 µA) and ±20% capacitance tolerance enable clear design margins and component selection.
• RoHS compliance: Conforms to RoHS requirements as called out for the RKS series.
