RKS1C101MCNAFEGS

The RKS1C101MCNAFEGS is a surface‑mount conductive polymer aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 100 µF capacitance at a 16 V rating with a compact φ6.3 × 5.8 mm SMD can package and embossed carrier taping with moisture‑proof packing for automated assembly.

Engineered for elevated temperature and high‑ripple environments, this Nichicon RKS series part offers low ESR (50 mΩ at 100 kHz), measured leakage current limits, and a 3,000‑hour endurance at 125°C—traits that support robust decoupling and filtering in compact power designs.

Key Features

• Capacitance & Tolerance — 100 µF nominal capacitance with tolerance −20% to +20% (measured at 20°C, 120 Hz).
• Rated Voltage — 16 V DC rating suitable for many low‑voltage power rails and decoupling applications.
• Low Loss & Dissipation — tanδ (DF) of 0.12 at 20°C, 120 Hz, supporting efficient filtering with controlled dielectric loss.
• Low ESR — 50 mΩ ESR at 20°C/100 kHz, enabling effective high‑frequency ripple attenuation.
• High Ripple Current Capability — 100 mA at 120 Hz (low frequency) and 1 A at 300 kHz (high frequency) for sustained AC stress handling.
• Leakage and Reliability — leakage current specified at 100 µA with endurance rated 3,000 hours at 125°C under rated voltage.
• Wide Temperature Range — specified for operation from −55°C to +125°C to accommodate elevated ambient environments.
• SMD Package & Assembly — radial can SMD package (φ6.3 × 5.8 mm) with embossed carrier taping and moisture‑proof packing; compatible with lead‑free reflow up to 260°C peak per the series reflow specification.
• RoHS Compliant — meets RoHS directive requirements as indicated in the product data.

Typical Applications

• Power Supply Decoupling — compact surface‑mount capacitor for smoothing and local decoupling on low‑voltage DC rails.
• DC‑DC Converter Outputs — low ESR and high allowable ripple current make it suitable for output filtering in switching regulators.
• High‑Frequency Filtering — ESR of 50 mΩ at 100 kHz and 1 A ripple capability at 300 kHz support high‑frequency noise suppression.
• Compact Power Modules — small φ6.3 × 5.8 mm can package fits space‑constrained SMD assemblies while retaining long‑life performance at elevated temperatures.

Unique Advantages

• High‑temperature endurance: 3,000 hours at 125°C under rated voltage provides predictable long‑term performance in hot environments.
• Low ESR for efficient filtering: 50 mΩ ESR at 100 kHz reduces ripple and heat generation in high‑frequency circuits.
• Designed for high ripple loads: Specified ripple currents (100 mA @120 Hz; 1 A @300 kHz) support sustained AC stress on power rails.
• SMD assembly ready: Embossed carrier taping and moisture‑proof packing streamline automated placement and reflow processing up to the series' 260°C peak condition.
• Compact footprint: φ6.3 × 5.8 mm can delivers 100 µF in a small surface‑mount package for space‑constrained designs.
• Regulated leakage behavior: Leakage current specified and conditioned per the datasheet supports predictable bias performance after voltage application.
