RDS0E471MCNAFEGS

The RDS0E471MCNAFEGS is a surface‑mount conductive polymer aluminum electrolytic capacitor offering 470 µF capacitance at 2.5 V. Designed for compact assemblies, it delivers high capacitance and high ripple current in an SMD radial can footprint.

Key value propositions include low ESR (25 mΩ at 100 kHz), extended elevated‑temperature life (3000 hours at 125°C), and lead‑free reflow compatibility to 260°C peak—making it suitable for designs that require robust decoupling and energy storage in confined board space under demanding thermal conditions.

Key Features

• Electrolyte / Construction Conductive polymer aluminum solid electrolytic construction for stable performance and low loss.
• Capacitance and Tolerance 470 µF rated capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage 2.5 V nominal rating (surge voltage 2.8 V as per series data).
• Low ESR ESR ≤ 25 mΩ measured at 100 kHz, 20°C—supports effective high‑frequency filtering.
• High Ripple Current Capability Rated ripple current up to 1.05 A at 300 kHz and 105 mA at 120 Hz, with frequency coefficients provided for other bands.
• Extended Elevated‑Temperature Life Endurance specified at 3000 hours at 125°C under rated voltage, with capacitance, tan δ and ESR limits defined after test.
• Wide Operating Temperature Range Specified for −55°C to +125°C operation.
• SMD / Reflow Compatibility Surface‑mount radial can (φ6.3×5.7 mm) designed for lead‑free reflow processes up to 260°C peak.
• Compact Footprint Part dimensions: 6.3 × 5.7 mm (D × L), land pattern guidance L: 6.5 × W: 6.5 mm for PCB layout.

Typical Applications

• High‑ripple power stages — Use where high ripple current handling (1.05 A at 300 kHz) and 470 µF capacitance are needed for smoothing and energy buffering.
• Compact power supplies — Surface‑mount radial can and small footprint (6.3×5.7 mm) enable high capacitance in space‑constrained supply designs.
• Elevated‑temperature systems — Rated for −55°C to 125°C with 3000‑hour life at 125°C, suitable for circuits exposed to sustained high ambient temperatures.

Unique Advantages

• High energy density in SMD form factor: 470 µF at 2.5 V in a 6.3×5.7 mm package reduces board area compared with larger discrete solutions.
• Low ESR at high frequency: 25 mΩ (100 kHz) supports lower loss and improved filtering performance in high‑frequency converters.
• Robust ripple handling: Rated ripple currents up to 1.05 A at 300 kHz enable reliable operation in high‑frequency switching applications.
• Designed for elevated‑temperature reliability: 3000‑hour load life at 125°C provides predictable end‑urance for long‑life thermal environments.
• Lead‑free reflow compatible: Engineered for lead‑free peak reflow of 260°C to integrate with modern SMT assembly flows.
