RKS1V470MCNAHHGS

The RKS1V470MCNAHHGS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can. It delivers 47 µF at 35 V with low equivalent series resistance and engineered ripple-current capability for demanding power handling on compact PCBs.

Designed for applications that require sustained operation at elevated temperatures, this SMD capacitor provides a combination of low ESR, controlled loss (tanδ), and extended endurance suitable for power filtering, decoupling and high-frequency smoothing in industrial and electronics systems.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance rated at 35 V with capacitance tolerance of −20% to +20% (120 Hz, 20°C).
• Low ESR & High‑frequency performance — ESR of 30 mΩ measured at 20°C/100 kHz, supporting high-frequency smoothing and stable performance under dynamic loads.
• High allowable ripple current — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency), enabling effective ripple handling in power rails and switching converters.
• Controlled loss and leakage — tanδ of 0.12 (20°C, 120 Hz) and leakage current specified at 100 µA, for predictable AC and DC behavior.
• Extended high‑temperature endurance — Rated for operation from −55°C to +125°C with a load life of 3000 hours at 125°C, delivering reliable long-term performance in thermally challenging environments.
• SMD package & assembly compatibility — Radial can SMD package sized φ8 × 8.7 mm with recommended land size 8.3 × 8.3 mm; compatible with lead‑free reflow profiles up to 260°C peak (measurement at capacitor top), with specified pre‑heat and peak-time limits per the product datasheet.
• Packaging & production status — Supplied in embossed carrier taping with moisture proof packing; product is in mass production and RoHS compliant.

Typical Applications

• Power-supply filtering — Low ESR and 1.6 A high-frequency ripple rating make this capacitor well suited for bulk and output filtering in DC–DC converters and linear regulators.
• Switching power stages — High ripple-current capability and low loss (tanδ) support stable decoupling close to switching devices and power ICs.
• Industrial electronics — Extended temperature range (−55°C to +125°C) and 3000-hour endurance at 125°C enable reliable operation in thermally demanding control and instrumentation systems.
• High-frequency smoothing — ESR specified at 100 kHz and controlled tanδ allow effective smoothing in circuits operating with high switching frequencies.

Unique Advantages

• High-temperature endurance: 3000 hours at 125°C provides predictable aging and extended service life for high-temperature applications.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces output ripple and power loss in high-frequency power stages.
• Strong ripple handling: 1.6 A HF ripple rating and 160 mA LF rating permit compact decoupling solutions without oversizing components.
• Reflow-ready SMD can: Compatibility with lead-free reflow up to 260°C simplifies placement in modern SMT assembly flows.
• Compact footprint: φ8 × 8.7 mm package and recommended land size of 8.3 × 8.3 mm save board area while delivering bulk capacitance.
• Regulatory alignment: RoHS compliant construction supports environmental and regulatory requirements.
