RDS0G271MCNAHFGS

The RDS0G271MCNAHFGS is a conductive polymer aluminum solid electrolytic capacitor designed for surface-mount applications that require high capacitance and elevated ripple handling. As an SMD radial can in the Nichicon RDS series, it delivers 270 µF at 4 V with low ESR and extended thermal endurance.

Engineered for compact power designs, the part targets applications where high ripple current, compact board area, and reliable operation up to 125°C are important design drivers.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a rated voltage of 4 V with ±20% tolerance (120 Hz, 20°C).
• Conductive Polymer Electrolyte — Solid polymer construction providing high capacitance in a compact SMD can.
• Low ESR — ESR specified at 18 mΩ measured at 100 kHz, 20°C for improved power transfer and reduced loss.
• High Ripple Current — Rated ripple current up to 1.05 A at 300 kHz (and 105 mA at 120 Hz), supporting switching regulator outputs and other high-frequency power stages.
• Thermal Endurance — Load life specified as 3000 hours at 125°C, with endurance limits defined for capacitance, tan δ and ESR.
• Wide Operating Temperature — Specified operating range from −55°C to +125°C.
• SMD Package — Radial can SMD, case size 8.0 × 6.7 mm (φD × L) with recommended land size 8.3 × 8.3 mm for surface-mount assembly.
• Lead‑Free Reflow Compatible — Conforms to lead-free reflow soldering conditions with a 260°C peak.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk smoothing and output decoupling on DC–DC converter outputs where high ripple current and low ESR are required.
• Switching regulator support — Local energy storage and ripple absorption in compact SMD power stages operating at hundreds of kHz.
• Industrial and telecommunications electronics — Designs requiring extended high-temperature endurance (3000 hours at 125°C) and reliable SMD mounting.

Unique Advantages

• High ripple capability: 1.05 A at 300 kHz lets the capacitor absorb switching transients and reduce output voltage ripple in high-frequency converters.
• Low ESR performance: 18 mΩ at 100 kHz minimizes conduction losses and improves regulator stability and efficiency.
• Extended thermal life: 3000 hours at 125°C supports long-term reliability in hot operating environments.
• Compact SMD can: 8.0 × 6.7 mm footprint and 8.3 × 8.3 mm recommended land area save board space while providing high capacitance.
• Lead‑free assembly ready: Rated for 260°C peak lead-free reflow, simplifying integration into modern RoHS-compliant production flows.
