Overview of RNE1C391MCS1 – Conductive Polymer Aluminum Electrolytic Capacitor, Radial Lead

The RNE1C391MCS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, offering 390 µF capacitance at a 16 V rating. It combines high capacitance density with low equivalent series resistance (ESR) and elevated ripple-current capability for general-purpose electronic designs.

Designed for compact power-handling applications, the component targets designers who need robust smoothing, decoupling and bulk energy storage in small radial packages while maintaining wide operating temperature range and RoHS compliance.

Key Features

  • Dielectric / Construction Conductive polymer solid electrolytic design for stable capacitance and improved high-frequency behavior compared to conventional wet electrolytes.
  • Capacitance & Voltage 390 µF nominal capacitance with a 16 V rated voltage and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
  • Low ESR & High Ripple Capacity ESR of 15 mΩ (20°C, 100 kHz) with ripple current ratings of 350 mA at 120 Hz and 3.5 A at 300 kHz, supporting demanding AC load conditions.
  • Loss Characteristics tan δ = 0.08 (measured at 20°C, 120 Hz), indicating low dielectric loss for efficient operation at typical signal frequencies.
  • Reliability & Lifetime Rated for 2000 hours at 105°C under rated voltage, with leakage current specified as 1248 µA (measured after 2 minutes at 20°C).
  • Mechanical & Packaging Compact radial-can footprint: φ6.3 × 10 mm, lead spacing 2.5 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing for flexible assembly options.
  • Operating Range & Compliance Wide operating temperature range from −55°C to +105°C and RoHS compliant.

Typical Applications

  • General-purpose electronic circuits — Bulk capacitance and polarization suited to a wide range of board-level power and signal circuits classified as general purpose.
  • Power rail decoupling and smoothing — 390 µF capacitance combined with 15 mΩ ESR and high ripple-current capability supports filtering and smoothing of DC power rails.
  • Compact power modules — Small φ6.3 × 10 mm radial package fits space-constrained power delivery modules requiring high capacitance density.
  • Industrial and embedded electronics — Wide −55°C to +105°C operating range and 2000 h at 105°C life rating help support designs exposed to extended temperature ranges.

Unique Advantages

  • High ripple tolerance: 3.5 A ripple current capability at high frequency (300 kHz) enables reliable performance under dynamic load conditions.
  • Low AC loss: 15 mΩ ESR at 100 kHz and tan δ of 0.08 at 120 Hz reduce dissipation and improve efficiency in power circuits.
  • Compact, leaded form factor: φ6.3 × 10 mm radial can with 2.5 mm lead spacing offers easy through-hole mounting while minimizing board area.
  • Robust temperature endurance: −55°C to +105°C operating range and 2000-hour life at 105°C support long-term stability in elevated-temperature environments.
  • RoHS compliant: Meets RoHS directive requirements for lead-free manufacturing environments.
