RKS1D470MCNAHGGS

The RKS1D470MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RKS series. It provides 47 µF nominal capacitance at a 20 V rating in a compact φ8 × 7.7 mm SMD can package with embossed carrier tape and moisture-proof packing.

Designed for applications that demand low ESR and high ripple handling across a wide temperature range, this part delivers stable performance from −55 °C to +125 °C and a rated load life of 3000 hours at 125 °C.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 20 V rated voltage and tolerance of −20% to +20%.
• Low ESR — Equivalent series resistance of 30 mΩ measured at 20 °C / 100 kHz, supporting efficient high-frequency decoupling.
• High Ripple Current Capability — Low-frequency ripple current of 160 mA (120 Hz) and high-frequency ripple current of 1.6 A (300 kHz) to reduce thermal stress in power circuits.
• Wide Temperature & Long Life — Operating range −55 °C to +125 °C with endurance rated at 3000 hours at 125 °C.
• Low Leakage — Leakage current specified at 100 µA, improving reliability in low-current bias conditions.
• Reflow Solder Compatible — SMD construction compatible with lead-free reflow processes (soldering profile up to a 260 °C peak, per series specification).
• Packaging — Supplied in embossed carrier tape with moisture-proof packing for automated assembly.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply decoupling: Low ESR and high ripple current ratings make this capacitor suitable for smoothing and decoupling in power converters and regulator outputs.
• High-frequency power circuits: 30 mΩ ESR at 100 kHz and 1.6 A ripple capability support stable performance in high-frequency switching environments.
• Elevated-temperature electronics: Rated operation to +125 °C and a 3000 hour load life at 125 °C suit designs exposed to sustained high temperatures.

Unique Advantages

• Reliable high-temperature endurance: 3000 hours at 125 °C provides predictable lifetime behavior for designs operating at elevated ambient temperatures.
• Reduced board-level heating: Low ESR (30 mΩ) and high ripple current capability lower internal dissipation, helping manage thermal stress in dense power assemblies.
• SMD convenience for automated assembly: Embossed carrier tape packaging and reflow compatibility support pick-and-place and modern assembly flows.
• Compact, high-capacitance form factor: 47 µF in a φ8 × 7.7 mm can allows designers to conserve board area compared to larger through-hole options.
• Controlled leakage: Specified leakage current (100 µA) aids in predictable bias behavior for precision and low-current circuits.
• Regulatory compliance: RoHS conformance supports use in products subject to environmental directive requirements.
