RKS1C470MCNAFEGS

The RKS1C470MCNAFEGS is a surface-mount conductive-polymer aluminum electrolytic capacitor offering 47 µF capacitance at a 16 V rating. It is designed for general-purpose SMD applications that require compact bulk capacitance with low equivalent series resistance and high allowable ripple current.

Key value propositions include low ESR (50 mΩ at 100 kHz), high-frequency ripple handling, and extended high-temperature endurance — with a rated lifetime of 3000 hours at 125°C — in a compact φ6.3 × 5.8 mm SMD can package.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a rated voltage of 16 V and tolerance of ±20% (–20% to 20%).
• Conductive-Polymer Dielectric: Solid conductive-polymer construction for stable performance and reduced loss; tanδ = 0.12 (20°C, 120 Hz) as specified.
• Low ESR & High-Frequency Performance: ESR specified at 50 mΩ (20°C, 100 kHz) and rated high-frequency ripple current of 1 A (300 kHz), supporting high-speed decoupling and power-stage use.
• Ripple Current Capability: Low-frequency ripple current 100 mA (120 Hz) and high-frequency ripple current 1000 mA (300 kHz) for robust ripple handling across frequency ranges.
• Temperature & Endurance: Operating temperature range –55°C to 125°C with endurance specified as 3000 hours at 125°C and rated voltage.
• Leakage Current: Leakage current specified at 100 µA (after standard conditioning/measurement).
• SMD Can Package: Radial can SMD package, size φ6.3 × 5.8 mm (L × D), supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Assembly Compatibility: Lead-free reflow soldering to a 260°C peak is supported per product specification for SMD assembly processes.
• RoHS Compliant: Meets RoHS directive requirements as indicated in the product information.

Typical Applications

• Power rail decoupling: Local bulk decoupling on 16 V rails where low ESR and high ripple capability help stabilize voltage converters and regulators.
• DC-DC converters and point-of-load filters: Supports high-frequency switching environments with 50 mΩ ESR at 100 kHz and 1 A high-frequency ripple rating.
• Embedded and compact SMD designs: Small φ6.3 × 5.8 mm SMD can provides bulk capacitance in space-constrained boards while supporting automated placement and reflow.

Unique Advantages

• High-temperature endurance: 3000 hours at 125°C ensures predictable long-term behavior in elevated-temperature environments.
• Low ESR for improved transient response: 50 mΩ ESR at 100 kHz helps reduce voltage ripple and loss in high-frequency power stages.
• Broad ripple-frequency capability: Specified ripple current at both 120 Hz and 300 kHz addresses both low-frequency smoothing and high-frequency switching applications.
• Compact SMD form factor: φ6.3 × 5.8 mm package delivers 47 µF bulk capacitance in a small footprint suitable for automated assembly.
• Assembly-friendly packaging: Embossed carrier taping with moisture-proof packing supports high-volume surface-mount production and handling.
• Regulatory compliance: RoHS-compliant construction supports environmental directives for modern electronics manufacturing.
