RKS1V150MCNAFEGS

The RKS1V150MCNAFEGS is a surface-mount conductive polymer aluminum electrolytic capacitor in Nichicon’s RKS series. It delivers 15 µF capacitance at a 35 V rating with low ESR and high allowable ripple performance, packaged for automated assembly.

Designed for applications requiring compact SMD power decoupling and high-frequency ripple handling across a wide temperature range, this capacitor combines a long endurance rating at elevated temperatures with lead‑free reflow compatibility.

Key Features

• Capacitance & Voltage — 15 µF capacitance with a 35 V rated voltage and tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Conductive Polymer Electrolyte — Solid polymer construction provides stable electrical characteristics and low leakage, specified at 100 µA.
• Low ESR and High-Frequency Performance — ESR of 60 mΩ measured at 20°C/100 kHz, with high-frequency ripple current rating of 900 mA at 300 kHz for improved filtering and decoupling efficiency.
• Ripple Current Capability — Low-frequency ripple current rating of 90 mA at 120 Hz, supporting both low- and high-frequency ripple environments.
• High Temperature Endurance — Rated for operation from −55°C to +125°C with a load life of 3000 hours at 125°C.
• SMD Can Package — Compact φ6.3 × 5.8 mm can-style SMD package with recommended land size of 6.6 × 6.6 mm and embossed carrier taping for automated placement.
• Reflow Compatibility — Designed for lead‑free reflow soldering; peak profile compatibility to 260°C per datasheet soldering heat conditions.
• Regulatory — RoHS compliant.
• Dissipation Factor — tan δ of 0.12 at 20°C/120 Hz for predictable loss behavior in AC conditions.

Typical Applications

• High-frequency filtering and decoupling — Low ESR and high allowable ripple current make this capacitor suitable for smoothing and decoupling at elevated switching frequencies.
• Power stages operating at elevated temperatures — Endurance rated to 3000 hours at 125°C enables reliable use in designs exposed to high ambient or local temperatures.
• Compact SMD power modules — Small φ6.3 × 5.8 mm SMD can supports space-constrained power and energy storage applications where automated assembly is required.

Unique Advantages

• Robust high-temperature life: 3000 hours at 125°C provides long-term stability for designs that run hot or are exposed to harsh thermal environments.
• Low ESR for efficient filtering: 60 mΩ at 100 kHz helps reduce voltage ripple and heating in high-frequency applications.
• High ripple capacity across frequencies: 900 mA at 300 kHz and 90 mA at 120 Hz give flexibility for both switching and line-frequency ripple conditions.
• Compact, assembly-friendly package: φ6.3 × 5.8 mm SMD can with embossed carrier taping and moisture-proof packing for reliable pick-and-place and reflow processing.
• Predictable loss characteristics: tan δ = 0.12 (20°C/120 Hz) supports consistent AC performance in filter and decoupling networks.
• Compliance and process readiness: RoHS compliance and lead‑free reflow compatibility to 260°C simplify regulatory and manufacturing workflows.
