Overview of RS61C181MCN1 – Conductive Polymer Aluminum Solid Electrolytic Capacitor, 180 µF, 16 V

The RS61C181MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can package, offering 180 µF capacitance at a 16 V rating. Designed for general‑purpose electronics, it delivers low ESR and high ripple current in a miniature footprint for compact board-level power and filtering applications.

With an operating temperature range of −55°C to +105°C and a rated life of 2000 hours at 105°C, this RoHS‑compliant, mass‑production part is suited to designs that require reliable decoupling and smoothing under elevated temperature and high‑frequency ripple conditions.

Key Features

  • Core Technology — Conductive polymer aluminum solid electrolyte construction for improved conductivity and stability compared with conventional electrolytes.
  • Capacitance & Voltage — 180 µF nominal capacitance at a 16 V rating with ±20% tolerance (measured at 120 Hz, 20°C).
  • Low ESR — 20 mΩ equivalent series resistance measured at 100 kHz and 20°C to support lower loss and better voltage stability under load.
  • High Ripple Current — Rated ripple current of 320 mA at 120 Hz and 3.2 A at 300 kHz (frequency coefficient applied) for demanding AC and switching environments.
  • Temperature & Endurance — Wide operating range from −55°C to +105°C with a load life specification of 2000 hours at 105°C.
  • Reliability Parameters — Specified tanδ of 0.1 and leakage current of 576 µA (measured at 20°C after 2 minutes) for predictable behavior in circuit.
  • Compact Radial Package — Miniature dimensions (L: 5 × D: 6.3 mm), radial lead spacing 2.5 mm, and radial can package for through‑hole mounting in space‑constrained layouts.
  • Availability & Compliance — RoHS compliant and in mass production; packaging options include bulk (no terminal forming) and bag packing.

Typical Applications

  • Power supply decoupling — Low ESR and high ripple current rating make the RS61C181MCN1 suitable for smoothing and decoupling at regulator outputs and local board power rails.
  • Switching regulator output filtering — High ripple current capability at high frequency supports output filtering in switching power stages.
  • Space‑constrained PCB designs — Miniature φ6.3×5 case and 2.5 mm lead spacing enable compact placement where board area is limited.
  • General‑purpose electronic circuits — Robust temperature range (−55°C to +105°C) and defined endurance make it applicable across a wide set of consumer and industrial board‑level functions.

Unique Advantages

  • Low loss under AC stress: 20 mΩ ESR at 100 kHz reduces heating and improves efficiency in high‑frequency circuits.
  • High ripple handling: Rated ripple current up to 3.2 A at 300 kHz supports demanding switching and AC ripple conditions.
  • Compact form factor: φ6.3×5 (L: 5 × D: 6.3 mm) size and 2.5 mm lead spacing ease integration into dense, through‑hole layouts.
  • Wide temperature tolerance: −55°C to +105°C operation supports extended environmental ranges for industrial and embedded applications.
  • Predictable long‑term behavior: Specified tanδ, leakage current, and a 2000‑hour life at 105°C provide measurable reliability metrics for design validation.
  • Production readiness: RoHS compliance and mass production status with bulk and bag packing options simplify sourcing and assembly planning.

Why Choose RS61C181MCN1?

The RS61C181MCN1 combines conductive‑polymer performance with a miniature radial package to deliver low ESR, high ripple capability, and defined endurance metrics. It is positioned for engineers who need a compact, reliable capacitor for board‑level power filtering and decoupling where measurable ripple and temperature performance are important.

This part is well suited to designers of power supplies, switching regulators, and general‑purpose electronic assemblies that require RoHS compliance, predictable leakage and tanδ behavior, and availability for production volumes.
