RKS1J150MCNAFEGS

The RKS1J150MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor with a nominal capacitance of 15 µF and a rated voltage of 63 V. It is engineered for SMD power applications that require high allowable ripple current and reliable high-frequency performance.

Key value propositions include low ESR (120 mΩ at 100 kHz), rated operation across –55°C to 125°C, and a long endurance of 3000 hours at 125°C, making it suitable for compact power modules and high-frequency decoupling in demanding thermal environments.

Key Features

• Chemistry — Conductive Polymer Aluminum: Solid polymer electrolyte construction delivers the low LC and high allowable ripple current characteristics specified in the product documentation.
• Capacitance & Voltage: 15 µF nominal capacitance with tolerance of −20% to +20% and a rated voltage of 63 V.
• Low ESR & Ripple Handling: ESR specified at 120 mΩ (20°C, 100 kHz); ripple capability rated at 70 mA (120 Hz) and 700 mA (300 kHz).
• High-Temperature Endurance: Operating temperature range −55°C to 125°C with a rated load life of 3000 hours at 125°C.
• Leakage & Dissipation: Leakage current specified at 100 µA; tanδ (DF) of 0.12 measured at 20°C, 120 Hz.
• Package & Assembly: Compact SMD radial can (φ6.3 × 5.8 mm), surface-mount land size 6.6 × 6.6 mm, supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow up to the 260°C peak condition described in the datasheet.
• Regulatory: RoHS compliant as noted in the product information.

Typical Applications

• High-frequency power rail decoupling: Low ESR and high ripple capability support stable decoupling on switching power rails and high-frequency converters.
• Compact power modules: Small φ6.3 × 5.8 mm SMD can allows placement in space-constrained power assemblies requiring elevated temperature endurance.
• SMT board-level smoothing: Designed for surface-mount assembly and lead-free reflow processes to provide bulk smoothing and noise attenuation in densely populated PCBs.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low and high frequencies (70 mA @120 Hz, 700 mA @300 kHz) reduce thermal stress in high-duty power applications.
• Low ESR at high frequency: 120 mΩ ESR (100 kHz) supports effective energy transfer and minimizes voltage drop under dynamic loads.
• Extended high-temperature life: 3000 hours endurance at 125°C enables reliable operation in elevated-temperature environments.
• Surface-mount convenience: SMD radial can and embossed carrier taping simplify automated pick-and-place and reflow assembly flows.
• Predictable leakage and dissipation: Leakage current specification (100 µA) and tanδ (0.12 at 20°C, 120 Hz) provide measurable parameters for thermal and bias planning.
