RDS1C390MCNAFEGS

The RDS1C390MCNAFEGS from Nichicon is a conductive polymer aluminum solid electrolytic surface-mount capacitor offering 39 µF at 16 V. It is designed for compact PCB power subsystems that require high capacitance, low ESR and sustained performance across a wide operating temperature range.

Key value propositions include high ripple-current capability, a 3000‑hour load life rating at 125°C, and lead‑free reflow compatibility (260°C peak), making it suitable for robust, high‑temperature PCB assembly and power-filtering roles.

Key Features

• Capacitance & Voltage — Rated at 39 µF and 16 V with ±20% tolerance, providing bulk and decoupling capacitance for 16 V rails.
• Conductive Polymer Dielectric — Solid electrolyte construction for high capacitance density and stable electrical performance.
• Low ESR — ESR of 24 mΩ measured at 100 kHz, 20°C, supporting improved efficiency in high‑frequency power circuits.
• High Ripple Current — Rated ripple currents of 180 mA at 120 Hz and 1.8 A at 300 kHz, enabling effective smoothing under varied switching frequencies.
• Wide Temperature & Endurance — Operates from −55°C to +125°C with a specified load life of 3000 hours at 125°C.
• SMD, Reflow Compatible — Surface mount can package (φ6.3×L5.7 mm) compatible with lead‑free reflow soldering at 260°C peak.
• Polarized — Standard polarized capacitor for DC applications where polarity is defined.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power rail decoupling — Local energy storage and smoothing for 16 V power rails where high capacitance and low ESR reduce voltage ripple.
• Switching regulator output filtering — Supports DC‑DC converter outputs by handling high ripple currents at switching frequencies.
• Compact surface-mount power modules — Small φ6.3×5.7 mm can package and SMD footprint for space-constrained boards that undergo lead‑free reflow.
• Industrial and high-temperature electronics — Suitable for designs that require operation up to 125°C and a demonstrated 3000‑hour load life at that temperature.

Unique Advantages

• Long high‑temperature endurance: 3000 hours at 125°C supports extended reliability in thermally demanding deployments.
• High-frequency capability: Low ESR (24 mΩ at 100 kHz) and a 1.8 A ripple rating at 300 kHz enable efficient performance in high-speed switching environments.
• Compact SMD can package: φ6.3×5.7 mm size and a 6.5×6.5 mm recommended land area let designers save board area without sacrificing capacitance.
• Lead‑free reflow ready: Rated for 260°C peak lead‑free reflow, simplifying assembly with modern SMT processes.
• Wide operating range: −55°C to +125°C operation covers demanding ambient and thermal conditions for many electronic systems.
• RoHS conformity: Meets current RoHS requirements for regulated materials compliance.
