RDS0J331MCNAFEGS

The RDS0J331MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for compact assemblies that require high capacitance and robust ripple-handling capability. It delivers a 330 µF capacitance at a 6.3 V rating in a small SMD can package.

Engineered for elevated-temperature operation and long-term stability, this part supports continuous operation from −55 °C to 125 °C with a rated load life of 3000 hours at 125 °C. The device is compatible with lead-free reflow processes (260 °C peak) and is RoHS compliant.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a 6.3 V rated voltage with ±20% tolerance, suitable for bulk decoupling in compact designs.
• Conductive Polymer Dielectric — Solid polymer formulation for improved ripple current performance and stability across temperature.
• Low ESR — 25 mΩ equivalent series resistance (ESR) measured at 100 kHz, enabling efficient high-frequency current handling and reduced losses.
• High Ripple Current — Rated ripple current of 180 mA at 120 Hz and up to 1.8 A at 300 kHz, supporting demanding power-conditioning and switching applications.
• High-Temperature Endurance — Load life of 3000 hours at 125 °C, with endurance characteristics defined for capacitance, tan δ and ESR.
• Surface-Mount, Reflow-Compatible Package — Radial can SMD package (φD×L = 6.3 × 5.7 mm) with a surface mount land size of 6.5 × 6.5 mm; compatible with lead-free reflow soldering up to 260 °C peak.
• Wide Operating Range — Rated for operation from −55 °C to +125 °C, supporting applications exposed to elevated ambient temperatures.
• Polarized — Polarized electrolytic type for correct circuit orientation and predictable behavior in DC applications.

Typical Applications

• Compact power filtering: Bulk and output filtering where 6.3 V, 330 µF and low ESR (25 mΩ) improve transient response and reduce ripple on power rails.
• Switching power supplies: SMD-friendly high ripple current capability makes this part suitable for decoupling and output stages in DC–DC converter modules.
• High-temperature electronics: Long load life at 125 °C and an operating range to −55 °C support power subsystems in thermally demanding environments.

Unique Advantages

• High capacitance in a small footprint: 330 µF in a φ6.3 × 5.7 mm SMD can minimizes board area while providing bulk energy storage.
• Improved thermal reliability: 3000-hour load life at 125 °C gives designers a measurable endurance metric for elevated-temperature deployments.
• High-frequency performance: Low ESR at 100 kHz and rated ripple current to 300 kHz reduce losses and heating in high-switching-rate circuits.
• Assembly-ready: Lead-free reflow compatibility to a 260 °C peak simplifies integration into modern SMT production flows.
• Standards-compliant: RoHS (2011/65/EU, (EU)2015/863) compliance for regulated production environments.
