Overview of RKS1H180MCNAFGGS – Conductive Polymer Aluminum Solid Electrolytic SMD Capacitor, 18 µF / 50 V

The RKS1H180MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RKS series. It delivers 18 µF capacitance at a 50 V rating with low equivalent series resistance and high allowable ripple current for demanding power applications.

Designed for elevated operating temperatures and lead‑free reflow processes, this part targets power filtering and decoupling roles where compact size, low ESR, and long life at high temperature are required.

Key Features

  • Capacitance & Tolerance — 18 µF nominal capacitance with ±20% tolerance (measured at 20°C, 120 Hz).
  • Voltage Rating — Rated for 50 V operation.
  • Low ESR & High Ripple Handling — ESR of 40 mΩ at 20°C/100 kHz and high-frequency ripple current rating of 1.1 A (300 kHz), supporting efficient high-frequency filtering.
  • Leakage & Loss — Leakage current specified at 100 µA and tan δ (loss tangent) of 0.12 (20°C, 120 Hz), enabling predictable loss and leakage behavior.
  • Extended Temperature & Lifetime — Operating range −55°C to +125°C with endurance rated 3000 hours at 125°C.
  • Package & Mounting — Surface-mount radial can (φ6.3 × 7.7 mm) with surface mount land size L: 6.6 × W: 6.6 mm; supplied in embossed carrier taping and moisture-proof packing for automated assembly.
  • Assembly Compatibility — Compatible with lead‑free reflow soldering; specified peak reflow temperature correspondence up to 260°C.
  • Environmental — RoHS compliant.

Typical Applications

  • High-frequency power filtering — Low ESR and 1.1 A high‑frequency ripple rating make this capacitor suited to output filtering in switching power stages.
  • Point-of-load decoupling — Compact SMD radial-can footprint provides capacitance and ripple handling for local decoupling on power rails.
  • Industrial and telecom power systems — Extended −55°C to +125°C temperature range and 3000-hour endurance at 125°C support use in high‑temperature electronics environments.

Unique Advantages

  • Low ESR for efficient HF filtering: 40 mΩ at 100 kHz reduces conduction losses and improves filtering performance at high switching frequencies.
  • High ripple capability: Rated for 1.1 A at 300 kHz and 110 mA at 120 Hz to handle demanding ripple currents typical in power conversion stages.
  • High-temperature endurance: 3000 hours at 125°C gives predictable ageing and reliability in elevated-temperature installations.
  • Compact SMD radial-can package: φ6.3 × 7.7 mm footprint and compatible land pattern enable dense board layouts while retaining axial can robustness.
  • Reflow assembly compatible: Specified for lead‑free reflow up to 260°C peak, simplifying integration into modern surface-mount manufacturing flows.
  • Controlled leakage and dissipation: 100 µA leakage spec and tan δ of 0.12 provide stable electrical behavior for precision power designs.
