RKS1V390MCNAHHGS

The RKS1V390MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 39 µF at a 35 V rating in a compact φ8 × 8.7 mm SMD can, combining low ESR and high allowable ripple characteristics.

Designed for SMD assemblies that require stable performance at elevated temperatures, this part targets applications needing low loss, strong high‑frequency performance, and robust endurance up to 125°C.

Key Features

• Capacitance & Voltage — 39 µF nominal capacitance with a 35 V rated voltage and a tolerance of −20% to +20%.
• Low Loss / High Frequency Performance — tanδ of 0.12 measured at 20°C, 120 Hz and an ESR of 30 mΩ at 20°C, 100 kHz for low AC impedance at high frequencies.
• Ripple Current Capability — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) provide flexibility across modulation and switching frequencies.
• High-Temperature Endurance — Rated operating temperature range −55°C to +125°C with a life/endurance specification of 3000 hours at 125°C.
• Surface-Mount Packaging — Radial can SMD package (φ8 × 8.7 mm) optimized for SMD placement; supplied in embossed carrier taping with moisture-proof packing for production readiness.
• Leakage Current & Reliability — Leakage current specified at 100 µA and endurance characteristics defined per the RKS series to support reliable long-term operation.
• Lead‑Free Reflow Compatible — SMD type compatible with lead-free reflow soldering up to a 260°C peak per series soldering resistance specifications.
• RoHS Compliance — RKS series is stated as compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑ripple SMD power circuits — For SMD designs that demand low LC and high allowable ripple current in limited board area.
• High‑temperature electronic assemblies — Suitable where components must operate reliably up to 125°C with a 3000-hour high-temperature endurance rating.
• Lead‑free reflow production — Built for PCB assemblies using lead‑free reflow processes with verified soldering heat resistance.

Unique Advantages

• Low ESR at high frequency: 30 mΩ (100 kHz) ESR helps minimize voltage ripple and loss in switching and high‑frequency domains.
• Broad ripple capability across frequencies: Rated ripple currents of 160 mA (120 Hz) and 1.6 A (300 kHz) accommodate both low‑ and high‑frequency ripple loads.
• High‑temperature endurance: 3000 hours at 125°C provides a clear reliability target for thermally demanding applications.
• Production‑ready SMD format: Compact φ8 × 8.7 mm can in embossed carrier taping and moisture‑proof packing streamlines automated assembly and inventory handling.
• Lead‑free reflow tolerant: Conforms to lead‑free reflow soldering profiles up to 260°C, supporting modern assembly processes.
• RoHS directive compliance: Declared RoHS compliance for regulatory alignment in applicable regions.
