RKS1E101MCNAFGGS

The RKS1E101MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. Designed for compact power designs, it delivers 100 µF capacitance at a 25 V rating with low ESR and elevated ripple-current capability.

It is targeted at applications requiring high-frequency decoupling and robust thermal endurance, offering a combination of low loss (tanδ 0.12 at 20°C/120Hz), a wide operating temperature range (‑55°C to 125°C), and a 3000 hour life at 125°C.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 25 V rated voltage and tolerance of -20% to +20% for power rail stabilization.
• Low Loss & Low ESR — tanδ 0.12 (20°C, 120 Hz) and ESR of 30 mΩ measured at 20°C/100 kHz to minimize AC loss and heat under ripple conditions.
• High Ripple-Current Capability — 140 mA at 120 Hz (low frequency) and 1.4 A at 300 kHz (high frequency) for effective smoothing in switching power supplies and regulators.
• Extended Temperature & Endurance — Operating range from -55°C to 125°C with a rated life of 3000 hours at 125°C for reliable performance in thermally demanding environments.
• Compact SMD Package — Radial, can-style SMD package sized Ø6.3 × 7.7 mm that supports surface-mount assembly and embossed carrier taping with moisture-proof packing.
• Leakage Current Control — Specified leakage current of 125 µA for predictable quiescent behavior in power-sensitive designs.
• RoHS Compliant — Manufactured in conformity with RoHS requirements.

Typical Applications

• Power supply decoupling and smoothing — Low ESR and defined ripple-current ratings make the part suitable for bulk and output filtering on DC power rails.
• DC–DC converters and voltage regulators — High-frequency ripple capability (1.4 A at 300 kHz) and low loss support stable regulator output and transient response.
• Industrial and telecom electronics — Extended temperature range (‑55°C to 125°C) and 3000 h life at 125°C address elevated operating-temperature requirements.
• Compact SMD power modules — Small Ø6.3 × 7.7 mm SMD can fits space-constrained boards while enabling automated placement and reflow processes.

Unique Advantages

• Measurable low-ESR performance: 30 mΩ at 100 kHz reduces voltage ripple and power dissipation, improving thermal margin on dense power boards.
• High-frequency ripple handling: 1.4 A capability at 300 kHz supports modern switching topologies and high-speed converters.
• Designed for elevated ambient operation: 3000 hours endurance at 125°C helps maintain capacitance and ESR stability in hot environments.
• Compact SMD form factor: Ø6.3 × 7.7 mm radial can in embossed carrier tape for surface-mount assembly and high-density layouts.
• Predictable leakage behavior: Specified leakage current (125 µA) supports designs sensitive to quiescent currents and bias conditions.
• Standards-aligned manufacturing: RoHS compliance and reflow-capable construction support lead-free assembly flows.
