RKS1C470MCNAFGGS

The RKS1C470MCNAFGGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 47 µF capacitance at 16 V. Designed for general-purpose use, it provides high capacitance in a compact SMD radial can package (φ6.3 × 7.7 mm).

Key value comes from low ESR and high allowable ripple current combined with a wide operating temperature range (−55°C to +125°C) and a rated life of 3000 hours at 125°C, making it suitable where reliable power filtering and stable performance under thermal stress are required.

Key Features

• Core Type – Conductive Polymer Aluminum: Solid electrolyte construction for stable electrical characteristics and predictable leakage behavior (specified leakage current up to 100 µA).
• Electrical Performance: 47 µF capacitance with ±20% tolerance; tanδ (DF) 0.12 at 20°C/120 Hz; ESR 30 mΩ measured at 20°C/100 kHz.
• High Ripple Capability: Low-frequency ripple current 150 mA (120 Hz) and high-frequency ripple current 1.5 A (300 kHz), supporting demanding AC load conditions.
• Reliability & Lifetime: Rated for 3000 hours at 125°C under rated voltage conditions, with defined endurance and shelf-life characteristics per the RKS series datasheet.
• Temperature Range: Wide operating range from −55°C to +125°C to maintain performance across harsh thermal environments.
• Package & Mounting: Surface-mount radial can (φ6.3 × 7.7 mm) with embossed carrier taping and moisture-proof packing for automated placement. Marking uses navy blue print on the case top.
• Assembly Compatibility: SMD type rated for lead-free reflow soldering conditions up to a 260°C peak (reflow profile guidance provided in the series datasheet).
• Regulatory Compliance: RoHS compliant as stated in the product data.

Typical Applications

• General Power Filtering: Used for bulk smoothing and filtering in power rails where high capacitance and low ESR reduce voltage ripple and heat build-up.
• High-Frequency Decoupling: Supports decoupling at high switching frequencies thanks to low ESR and a 1.5 A high-frequency ripple rating.
• Thermally Demanding Electronics: Suited for designs that require reliable operation across −55°C to +125°C and a long load-life at elevated temperature (3000 hours at 125°C).

Unique Advantages

• Low ESR for Lower Losses: 30 mΩ ESR at 100 kHz minimizes power dissipation and improves thermal performance under ripple conditions.
• High Ripple Current Capability: Rated for 1.5 A at high frequency, enabling use in fast-switching power stages and regulators.
• Long High-Temperature Life: 3000 hours at 125°C provides predictable endurance for designs exposed to sustained high temperatures.
• Compact SMD Can: φ6.3 × 7.7 mm package delivers 47 µF in a small board footprint for space-constrained applications.
• Manufacturing-Ready Packaging: Embossed carrier taping with moisture-proof packing supports automated SMT workflows and inventory handling.
