RKS1E150MCNAFGGS

The RKS1E150MCNAFGGS is a conductive-polymer aluminum solid electrolytic capacitor in an SMD can package, offering 15 µF capacitance at a 25 V rating. It is part of Nichicon’s RKS series and is designed for surface-mount assembly with lead‑free reflow compatibility.

With low equivalent series resistance, high allowable ripple current and a wide operating temperature range, this capacitor is targeted at compact power designs that demand reliable decoupling, bulk filtering and high-frequency ripple handling in harsh thermal environments.

Key Features

• Core Technology — Conductive polymer aluminum solid electrolyte in an SMD radial can provides stable electrical characteristics and solderability for surface-mount assembly.
• Electrical — 15 µF nominal capacitance with ±20% tolerance and rated voltage of 25 V; tanδ (DF) 0.12 at 20°C, 120 Hz; leakage current specified at 100 µA.
• Low ESR & High Ripple Handling — ESR 30 mΩ measured at 20°C/100 kHz, with allowable ripple current of 140 mA at 120 Hz and 1.4 A at 300 kHz, supporting efficient decoupling and high-frequency filtering.
• Thermal & Endurance — Rated for −55°C to +125°C operating range with a rated load life of 3000 hours at 125°C.
• Assembly & Packaging — Surface-mount radial can (φ6.3 × 7.7 mm) designed for lead‑free reflow (peak 260°C per series guidance); supplied in embossed carrier taping with moisture-proof packing.
• Compliance — Series documentation indicates compliance with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Power-supply decoupling — Low ESR and high ripple-current capability make this part suitable for local decoupling on power rails where compact SMD solutions are required.
• Switching regulator output filtering — High-frequency ripple handling (1.4 A at 300 kHz) supports output-stage smoothing in switching power stages.
• Bulk filtering in compact modules — 15 µF capacitance in a small φ6.3 × 7.7 mm package provides bulk capacitance for space-constrained power modules and converters.
• High-temperature electronics — Endurance rated at 3000 hours at 125°C enables deployment in power assemblies that operate elevated temperatures.

Unique Advantages

• High ripple-current tolerance: 1.4 A at 300 kHz and 140 mA at 120 Hz allow use directly at point-of-load to reduce thermal stress on surrounding components.
• Low ESR for efficient decoupling: 30 mΩ ESR at 100 kHz reduces voltage drop and dissipation, improving converter stability and transient response.
• Robust high-temperature endurance: 3000 hours at 125°C provides predictable long-term performance in thermally demanding designs.
• Surface-mount convenience: Compact radial can (φ6.3 × 7.7 mm) and embossed carrier taping simplify automated placement and assembly.
• Lead‑free reflow compatible: Designed to withstand peak reflow temperatures up to 260°C as specified for the series, supporting modern RoHS-compliant assembly processes.
