Overview of RKS1J180MCNAHFGS – 18 µF, 63 V Conductive Polymer Aluminum SMD Capacitor

The RKS1J180MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor with 18 µF capacitance rated at 63 V. It combines low ESR and strong high-frequency ripple handling in a compact φ8 × 6.7 mm SMD can package.

Designed for compact power delivery and filtering roles, this part targets applications that require stable capacitance across a wide temperature range and long-term reliability under elevated operating temperatures.

Key Features

  • Capacitance & Voltage: 18 µF nominal capacitance rated for 63 V DC, with capacitance tolerance ±20% at 120 Hz, 20°C.
  • Low Loss / High Frequency Performance: tanδ = 0.12 (20°C, 120 Hz) and ESR of 40 mΩ measured at 20°C/100 kHz, supporting high-frequency decoupling and filtering.
  • Ripple Current Capability: 110 mA at 120 Hz (low frequency) and 1.1 A at 300 kHz (high frequency), enabling effective ripple absorption in switching regulator and converter circuits.
  • Wide Temperature & Endurance: Rated for operation from −55°C to +125°C with an endurance (load life) of 3000 hours at 125°C.
  • Leakage & Polarization: Polarized SMD capacitor with leakage current specified up to 100 µA after standard conditioning.
  • Compact SMD Package & Assembly: φ8 × 6.7 mm can-style SMD (radial, can - SMD) supplied in embossed carrier taping with moisture-proof packing suitable for reflow processes.
  • RoHS Compliant: Meets RoHS directive requirements as indicated in the product documentation.

Typical Applications

  • Power-supply decoupling: Low ESR (40 mΩ) and 1.1 A high-frequency ripple capability make this capacitor suited for output and bulk decoupling in DC–DC converters and regulator stages.
  • Switching regulator input filters: The combination of high ripple current rating and compact SMD can package supports input filtering where space and thermal endurance are constrained.
  • High-frequency filtering in communication equipment: Stable high-frequency behavior and low loss factor help maintain signal integrity and voltage stability in RF and telecom modules.
  • Industrial control electronics: Wide operating temperature range (−55°C to +125°C) and 3000-hour life at 125°C provide durability for thermally demanding control and power-management circuits.

Unique Advantages

  • High ripple tolerance: Rated ripple currents of 110 mA (120 Hz) and 1.1 A (300 kHz) enable effective smoothing in both low- and high-frequency environments.
  • Low ESR for efficient filtering: 40 mΩ ESR at 100 kHz reduces voltage drop and heat generation, improving regulator stability and converter efficiency.
  • Extended high-temperature endurance: 3000 hours life at 125°C supports long-term reliability in thermally stressed designs.
  • Compact SMD can form factor: φ8 × 6.7 mm SMD package provides high capacitance density for space-constrained board layouts and automated assembly.
  • Predictable leakage and loss characteristics: Leakage current up to 100 µA and tanδ = 0.12 at 20°C, 120 Hz offer a clear performance baseline for design verification.
  • Shipment-ready packaging: Supplied in embossed carrier taping with moisture-proof packing to support reflow assembly workflows.
