RKS1V470MCNAHGGS

The RKS1V470MCNAHGGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series. It delivers 47 µF at a 35 V rating with low equivalent series resistance and high allowable ripple current for compact power-electronics designs.

Engineered for elevated-temperature operation and robust SMD assembly, the device supports an operating range of −55°C to 125°C, a rated load life of 3000 hours at 125°C, and packaged for automated placement with embossed carrier taping and moisture-proof packing.

Key Features

• Capacitance & Voltage — Rated capacitance 47 µF at 35 V with tolerance −20% to +20% (measured at 20°C, 120 Hz).
• Low Loss (tan δ) — tan δ = 0.12 at 20°C, 120 Hz, supporting stable AC performance in filtering and decoupling roles.
• Low ESR — ESR of 30 mΩ measured at 20°C/100 kHz, enabling efficient high-frequency performance and reduced heat generation.
• High Ripple Current Capacity — Rated low-frequency ripple current 160 mA at 120 Hz and high-frequency ripple current 1.6 A at 300 kHz for demanding power stages.
• Leakage Current — Maximum leakage current of 100 µA after standard conditioning, aiding predictable bias behavior.
• Temperature & Endurance — Operating temperature range −55°C to 125°C with a rated life of 3000 hours at 125°C.
• SMD Package & Handling — Compact radial can SMD: φ8 × 7.7 mm (diameter × length), compatible with lead-free reflow (peak 260°C; reflow two times maximum per datasheet). Packaged in embossed carrier taping with moisture-proof packing for pick-and-place assembly.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Low ESR and high ripple-current capability make this capacitor suitable for bulk and post-regulator filtering in compact power supplies.
• Switching regulator outputs — High-frequency ripple rating (1.6 A at 300 kHz) supports decoupling at switching converter outputs and point-of-load stages.
• High-temperature electronics — Rated for −55°C to 125°C and 3000-hour life at 125°C for systems that operate in elevated ambient conditions.
• SMD board designs — Radial can SMD footprint and embossed carrier taping enable automated placement in dense surface-mount assemblies.

Unique Advantages

• High-temperature endurance: 3000 hours at 125°C provides extended operational life in thermally stressed environments.
• High ripple tolerance with low ESR: 30 mΩ ESR and 1.6 A high-frequency ripple capability reduce voltage ripple and power loss in switching applications.
• Predictable AC performance: Specified tan δ (0.12 at 20°C/120 Hz) and leakage limits support reliable filtering behavior over life.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated assembly and logistics.
• Reflow-compatible: Designed for lead-free reflow with a 260°C peak allowance (two cycles maximum) to match modern assembly processes.
• RoHS compliance: Meets applicable lead-free and hazardous-substance restrictions for global electronics manufacturing.
