RKS1H470MCNAJJGS

The RKS1H470MCNAJJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor with a rated capacitance of 47 µF and a rated voltage of 50 V. It is engineered for general-purpose electronic applications that require low ESR, high ripple-current capability and robust temperature endurance.

Key electrical attributes include a low ESR of 25 mΩ (measured at 100 kHz, 20°C), high allowable ripple currents (160 mA at 120 Hz and 1.6 A at 300 kHz) and an extended load life of 3000 hours at 125°C, delivering reliable performance across demanding operating conditions.

Key Features

• Core Technology — Conductive Polymer Aluminum: Solid polymer electrolyte construction provides stable electrical characteristics and improved high-frequency performance.
• Electrical Performance: 47 µF capacitance with ±20% tolerance (120 Hz, 20°C) and tanδ (DF) of 0.12 measured at 120 Hz, 20°C for predictable AC behavior.
• Low ESR: 25 mΩ equivalent series resistance at 100 kHz (20°C), supporting efficient power transfer and reduced power loss in high-frequency circuits.
• High Ripple-Current Capability: Rated for 160 mA at 120 Hz and 1.6 A at 300 kHz to handle both low- and high-frequency ripple demands.
• Wide Temperature Range and Endurance: Operates from −55°C to +125°C with a rated load life of 3000 hours at 125°C.
• Compact SMD Packaging: φ10 × 10 mm can-style SMD package (radial can — SMD) optimized for space-constrained assemblies and supplied in embossed carrier taping with moisture-proof packing.
• Polarized Device: Polar capacitor construction for applications that require polarized electrolytic capacitance.
• Manufacturing & Quality: Designed for lead-free reflow compatibility (260°C peak reflow condition) and supplied as a mass-production product.
• Regulatory: RoHS compliant.

Typical Applications

• General-purpose electronic assemblies: Provides bulk capacitance in a compact SMD can for a wide range of consumer and industrial circuits.
• High-frequency power circuits: Low ESR and high ripple-current capability suit switched-mode power supply stages and high-frequency decoupling.
• Industrial electronics operating across extreme temperatures: Rated for −55°C to +125°C with a 3000-hour life at 125°C for sustained performance in harsh environments.

Unique Advantages

• Low ESR for efficient power handling: 25 mΩ at 100 kHz minimizes losses and heat generation in high-frequency applications.
• High ripple-current margin: 1.6 A at 300 kHz and 160 mA at 120 Hz enable robust handling of both high- and low-frequency ripple components.
• Extended high-temperature endurance: 3000 hours at 125°C supports long-term operation in thermally challenging designs.
• Compact, production-ready SMD form factor: φ10×10 mm can in embossed carrier taping with moisture-proof packing simplifies automated assembly and inventory handling.
• Predictable AC characteristics: Specified tanδ (0.12 at 120 Hz) and ±20% capacitance tolerance aid design margining and frequency-response planning.
• RoHS compliant and lead-free reflow compatible: Supports modern manufacturing and environmental requirements.
