RKS1C390MCNAFGGS

The RKS1C390MCNAFGGS is a surface-mount conductive-polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers 39 µF capacitance at a 16 V rating in a compact φ6.3 × 7.7 mm SMD can package designed for general-purpose electronic designs.

Its combination of low ESR, high allowable ripple current and extended temperature and life ratings make it suitable for compact power and decoupling applications where reliability and thermal endurance are required.

Key Features

• Capacitance & Voltage — 39 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of ±20% at 20°C, 120 Hz.
• Low Loss Tangent — tanδ of 0.12 (measured at 20°C, 120 Hz) for stable performance in AC conditions.
• Low ESR — Equivalent Series Resistance of 30 mΩ measured at 20°C, 100 kHz to support efficient high-frequency filtering.
• High Ripple Current Capability — 150 mA at 120 Hz (low frequency) and 1.5 A at 300 kHz (high frequency) for demanding decoupling and power applications.
• Leakage Current — Specified leakage current up to 100 µA after stabilization, supporting predictable bias behavior.
• Extended Life and Temperature Range — Load life of 3000 hours at 125°C and operating temperature range from −55°C to +125°C for high-temperature endurance.
• SMD Package & Assembly Ready — φ6.3 × 7.7 mm radial can SMD package supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow (peak 260°C) profiles noted in the series datasheet.
• RoHS Compliant — Meets RoHS directive requirements as stated in the product information.

Typical Applications

• Power supply decoupling — Compact SMD form factor and 39 µF capacitance paired with 30 mΩ ESR help stabilize local rails and reduce voltage ripple.
• High-frequency power filtering — 1.5 A allowable ripple current at 300 kHz supports filtering in switching regulator outputs and point-of-load circuits.
• Embedded and industrial electronics — Wide −55°C to +125°C operating range and 3000-hour life at 125°C suit designs exposed to elevated temperatures.

Unique Advantages

• Compact high-performance SMD — Delivers 39 µF in a φ6.3 × 7.7 mm SMD can for space-constrained circuit boards.
• Low ESR for efficient HF performance — 30 mΩ ESR at 100 kHz reduces losses and improves high-frequency filtering effectiveness.
• High allowable ripple current — Rated for 150 mA (120 Hz) and 1.5 A (300 kHz), enabling use directly on switching nodes and regulator outputs.
• Thermal and lifecycle robustness — 3000 hours at 125°C endurance rating provides predictable long-term behavior in hot environments.
• Assembly-ready packaging — Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow processes referenced in the series datasheet.
• Regulatory compliance — RoHS-compliant construction aligns with modern environmental requirements.
