Overview of RKS1V221MCNAJLGS – 220 µF, 35 V Surface‑Mount Conductive Polymer Aluminum Electrolytic Capacitor

The RKS1V221MCNAJLGS is a surface‑mount conductive polymer aluminum electrolytic capacitor offering 220 µF capacitance at a 35 V rating. Designed for general‑purpose SMD power applications, it combines high capacitance density with low equivalent series resistance and robust high‑temperature endurance.

Key value propositions include a wide operating temperature range (−55°C to 125°C), a 3000‑hour life at 125°C, and packaging optimized for automated assembly (embossed carrier taping with moisture‑proof packing).

Key Features

  • Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 35 V and capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
  • Low ESR & High Ripple Capability — ESR of 20 mΩ measured at 20°C/100 kHz, low‑frequency ripple current 200 mA at 120 Hz, and high‑frequency ripple current 2 A at 300 kHz, supporting demanding decoupling and power‑supply applications.
  • High Temperature Endurance — Rated operating range −55°C to 125°C with a specified load life of 3000 hours at 125°C, delivering stable performance under elevated temperature stress.
  • Dielectric Loss (tan δ) — Tangent of loss angle 0.12 (measured at 20°C, 120 Hz), reflecting controlled dissipation for power applications.
  • Leakage Current — Specified leakage current of 385 µA, consistent with polarized electrolytic construction and the stated voltage rating.
  • SMD Package & Assembly — Radial, can‑style SMD package (φ10 × 12.4 mm length; L: 1.24 × D: 1.0 cm) supplied in embossed carrier taping with moisture‑proof packing; compatible with lead‑free reflow soldering to a 260°C peak.
  • Polarized Construction — Polarized capacitor suitable for DC power applications requiring bulk capacitance.
  • RoHS Compliance — Compliant to RoHS directive as stated in the product documentation.

Typical Applications

  • Power Supply Filtering — Bulk decoupling and smoothing in DC power rails where high capacitance and low ESR are required to stabilize voltage and reduce ripple.
  • DC‑DC Converters — Input/output filtering for switching regulators that require high ripple current handling and stable performance at elevated temperatures.
  • Embedded Power Modules — Local energy storage and transient buffering in compact SMD assemblies for industrial and consumer electronics.

Unique Advantages

  • High Temperature Reliability: 3000‑hour rated life at 125°C provides predictable long‑term behavior in thermally demanding environments.
  • Low ESR for Improved Efficiency: 20 mΩ ESR at 100 kHz lowers power loss and heat generation in high‑frequency power circuits.
  • Strong Ripple Handling: 2 A high‑frequency ripple rating supports high‑density switching applications and reduces the need for parallel capacitors.
  • SMD Packaging Optimized for Production: Embossed carrier taping and moisture‑proof packing streamline automated placement and handling in volume assembly.
  • Controlled Dissipation: tan δ of 0.12 at 20°C/120 Hz helps maintain stable performance in AC and switching environments.
