RKS1K150MCNAHFGS

The RKS1K150MCNAHFGS from Nichicon is a surface‑mount conductive polymer aluminum solid electrolytic capacitor in the RKS series. It delivers 15 µF capacitance at a rated voltage of 80 V in a compact φ8 × 6.7 mm SMD can package, engineered for general‑purpose power and decoupling applications.

Designed for long life and high ripple handling, this part offers a 3000‑hour endurance at 125°C, low ESR at high frequency, and packaging optimized for automated assembly, making it suitable for robust power‑supply and high‑frequency circuits.

Key Features

• Conductive‑polymer aluminum technology — Solid electrolytic construction for stable capacitance and reduced equivalent series resistance compared with traditional wet electrolytes.
• Electrical characteristics — 15 µF nominal capacitance with tolerance of −20% to 20% and rated voltage of 80 V for higher‑voltage rail applications.
• Low ESR at high frequency — ESR specified at 40 mΩ measured at 20°C/100 kHz, supporting effective decoupling and low loss in switching environments.
• High ripple current capability — Low‑frequency ripple current of 110 mA (120 Hz) and high‑frequency ripple current of 1.1 A (300 kHz) to handle switching and regulator ripple currents.
• Long operating life — Endurance rated 3000 hours at 125°C under rated voltage, supporting designs that require prolonged high‑temperature reliability.
• Wide operating temperature range — Specified from −55°C to 125°C for use across demanding thermal environments.
• SMD can package & assembly ready — φ8 × 6.7 mm SMD can (radial can – SMD); supplied in embossed carrier taping with moisture‑proof packing for pick‑and‑place; compatible with lead‑free reflow soldering (260°C peak).
• Leakage current — Specified leakage current up to 100 µA, facilitating predictable bias behavior in power circuits.
• Regulatory — Series datasheet indicates compliance with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling — Local energy storage and decoupling on intermediate and high‑voltage rails where 80 V rating and low ESR improve transient response.
• Switch‑mode power supplies — Supports input/output filtering and ripple absorption in high‑frequency converters thanks to high allowable ripple current and low ESR.
• DC/DC converters — Bulk and output smoothing on compact SMD layouts where long life at elevated temperatures is required.
• Industrial electronics — Robust thermal endurance (−55°C to 125°C) and long lifetime for controls, power modules, and instrumentation operating in harsh conditions.

Unique Advantages

• High‑voltage capability: 80 V rating expands usable range for higher‑voltage rails without stacking multiple parts.
• High ripple tolerance: Combined low ESR (40 mΩ at 100 kHz) and 1.1 A high‑frequency ripple rating reduce heating and improve reliability in switching applications.
• Long high‑temperature life: 3000 hours at 125°C provides predictable lifetime for designs exposed to sustained elevated temperatures.
• Assembly‑friendly packaging: Embossed carrier taping and moisture‑proof packing streamline automated pick‑and‑place and reflow processes.
• Compact SMD can format: φ8 × 6.7 mm footprint offers a high‑capacitance solution in a small package for space‑constrained boards.
