Overview of RKS1C681MCNAHJGS – Conductive Polymer Aluminum Solid Electrolytic SMD Capacitor, 680 µF, 16 V

The RKS1C681MCNAHJGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package (φ8×10L) offering 680 µF capacitance at 16 V. It delivers low equivalent series resistance (25 mΩ at 100 kHz), defined ripple current capability, and a wide operating temperature range for general-purpose electronic applications.

Designed for SMD assembly with embossed carrier taping and moisture-proof packing, this part targets designs that require high capacitance in a compact package with long endurance (3000 hours at 125°C) and RoHS compliance.

Key Features

  • Capacitance and Voltage — 680 µF nominal capacitance with a rated voltage of 16 V and tolerance of -20% to +20%.
  • Conductive Polymer Construction — Solid electrolytic conductive polymer chemistry providing stable performance and measurable loss characteristics (tanδ 0.12 at 20°C, 120 Hz).
  • Low ESR and High Ripple Capability — ESR of 25 mΩ at 100 kHz; ripple current ratings of 170 mA at 120 Hz (low frequency) and 1.7 A at 300 kHz (high frequency).
  • Thermal and Endurance Performance — Rated for operation from -55°C to 125°C with a load-life endurance of 3000 hours at 125°C.
  • Leakage and Reliability — Specified leakage current of 544 µA and endurance/shelf-life characteristics defined by Nichicon test conditions.
  • SMD Packaging and Assembly — Radial can SMD package (φ8×10L; L: 1.0 × D: 0.8 cm) supplied in embossed carrier taping with moisture-proof packing for pick-and-place assembly and reflow processing.
  • Regulatory — RoHS compliant.

Typical Applications

  • General-purpose electronic circuits — Provides bulk capacitance and decoupling where a 16 V, 680 µF capacitor with low ESR is required.
  • Power conversion and regulation — Suited for power modules and converters that need high ripple-current handling and stable ESR at high frequency.
  • Embedded systems and modules — Compact radial can SMD form factor fits space-constrained PCB designs requiring long endurance at elevated temperatures.

Unique Advantages

  • High capacitance in a compact SMD can — 680 µF in a φ8×10 mm package provides significant energy storage while conserving board area.
  • Low ESR for better power performance — 25 mΩ at 100 kHz minimizes losses and supports higher frequency decoupling needs.
  • Defined ripple-current capability — Separate low- and high-frequency ripple current ratings (170 mA @120 Hz; 1.7 A @300 kHz) allow designers to match component selection to application stress.
  • Wide temperature range and long life — Rated -55°C to 125°C with 3000 hours endurance at 125°C for reliable operation in demanding thermal environments.
  • Assembly-ready packaging — Embossed carrier taping and moisture-proof packing simplify surface-mount production workflows.
  • RoHS compliant — Meets regulatory requirements for lead-free applications.
