Overview of RKS1C121MCNAHHGS – 120 µF, 16 V Conductive Polymer SMD Aluminum Electrolytic Capacitor

The RKS1C121MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 120 µF at 16 V in a compact φ8 × 8.7 mm radial SMD can. Designed for general-purpose electronic applications, it combines low ESR and high allowable ripple current with a wide operating temperature range for demanding power environments.

Its construction and specifications target applications that require stable high-frequency performance, predictable leakage behavior, and long-term endurance up to 3000 hours at 125°C.

Key Features

  • Electrical Performance — 120 µF capacitance with ±20% tolerance and tanδ (DF) of 0.12 measured at 20°C, 120 Hz for predictable AC behavior.
  • Low ESR & High Ripple Capability — ESR of 30 mΩ measured at 20°C/100 kHz and ripple current ratings of 160 mA (120 Hz) and 1.6 A (300 kHz) to support high-frequency power handling.
  • Voltage & Leakage — Rated for 16 V with specified leakage current up to 100 µA after standard conditioning.
  • Thermal & Endurance — Wide operating temperature range from −55°C to 125°C and a rated load life/endurance of 3000 hours at 125°C with defined limits on capacitance change, tanδ and ESR.
  • Package & Assembly — Surface-mount radial can (φ8 × 8.7 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering (peak 260°C) per datasheet soldering profile.
  • Compliance — RoHS compliant.

Typical Applications

  • General-Purpose Electronics — Surface-mount use where a 120 µF, 16 V polarized capacitor is required for bulk or decoupling duties.
  • Power Supply Filtering — Low ESR (30 mΩ @100 kHz) and high allowable ripple current (1.6 A at 300 kHz) make it suitable for high-frequency filtering in power modules and converters.
  • High-Temperature Systems — Operation to 125°C with a 3000-hour rated life supports applications exposed to elevated operating temperatures.
  • Automated Assembly — Embossed carrier taping and moisture-proof packing plus compatibility with 260°C lead-free reflow profiles streamline high-volume SMD production.

Unique Advantages

  • Low ESR for stable high-frequency performance: 30 mΩ ESR at 100 kHz reduces voltage ripple and thermal stress under HF loading.
  • High allowable ripple current: 160 mA at 120 Hz and 1.6 A at 300 kHz enable reliable operation in both low- and high-frequency ripple environments.
  • Robust thermal endurance: Rated life of 3000 hours at 125°C with specified limits on capacitance change, tanδ and ESR for long-term reliability.
  • Compact SMD can package: φ8 × 8.7 mm radial can provides a small footprint while maintaining capacitor performance for space-constrained designs.
  • Assembly-friendly packaging: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow up to 260°C to support automated manufacturing.
  • Predictable leakage behavior: Leakage current specified at up to 100 µA, enabling controlled bias characteristics in circuit design.
