RKS1D101MCNAHGGS

The RKS1D101MCNAHGGS is a surface-mount conductive polymer aluminum electrolytic capacitor in the Nichicon RKS series. It delivers 100 µF capacitance at a 20 V rating with low ESR and elevated temperature endurance, making it suitable for board-level power systems that require compact, high-ripple handling capacitors.

Built for applications that demand low loss at high frequency and sustained operation at elevated temperatures, this SMD can supports robust filtering and decoupling in power conversion and high-frequency circuits.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 20 V rated voltage and ±20% tolerance (–20%~20%).
• Conductive Polymer Electrolyte — Solid conductive polymer construction for low tanδ (0.12 at 20°C, 120 Hz) and stable performance at frequency.
• Low ESR — ESR of 30 mΩ measured at 20°C / 100 kHz, enabling efficient high-frequency filtering and reduced loss.
• High Ripple Current Capability — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz), supporting high-ripple power applications.
• Leakage & Endurance — Leakage current specified at 100 µA and rated life of 3000 hours at 125°C for extended high-temperature operation.
• Temperature Range — Operating range −55°C to +125°C to cover a wide span of thermal environments.
• SMD Package — φ8 × 7.7 mm can-style SMD (radial can) for PCB mounting; supplied in embossed carrier taping with moisture-proof packing for pick-and-place assembly.
• Reflow Compatibility & RoHS — Designed for lead-free reflow soldering (260°C peak profile supported per datasheet guidance) and RoHS compliant.

Typical Applications

• Power supply decoupling — Local energy storage and smoothing for DC–DC converters and regulator outputs where low ESR and high ripple handling reduce voltage ripple.
• High-frequency power circuits — AC bypass and filtering in switching power stages that operate at hundreds of kilohertz, leveraging the 30 mΩ ESR at 100 kHz.
• Board-level bulk capacitance — Compact SMD bulk cap for space-constrained PCBs requiring sustained operation up to 125°C.

Unique Advantages

• Low-loss conductive polymer — Provides lower tanδ and stable high-frequency behavior for cleaner power rails.
• High ripple tolerance — 1.6 A high-frequency ripple rating reduces stress on the capacitor in switching applications and helps maintain performance under dynamic loads.
• Extended high-temperature life — 3000 hours at 125°C offers predictable endurance for designs exposed to elevated ambient or board temperatures.
• Compact SMD can — φ8 × 7.7 mm package balances capacitance and PCB footprint for efficient space utilization.
• Assembly-ready packaging — Embossed carrier taping with moisture-proof packing supports automated surface-mount assembly processes.
• RoHS compliant and reflow capable — Supports lead-free manufacturing flows in accordance with the datasheet reflow profile guidance.
