RDS0J221MCNAFEGS

The RDS0J221MCNAFEGS is a 220 µF, 6.3 V conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RDS series, delivered in a compact surface-mount radial can package. It combines high capacitance and high ripple-current capability with lead‑free reflow compatibility for compact, automated assembly.

Designed for elevated-temperature operation, the part is rated for –55 °C to 125 °C with a specified load life of 3000 hours at 125 °C. Key electrical characteristics include low ESR and controlled leakage current, making it suitable where robust power filtering and thermal endurance are required.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic construction for stable capacitance and improved ripple performance compared with conventional electrolytes.
• Capacitance & Voltage 220 µF rated capacitance at 6.3 V with capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Low ESR & High Ripple Handling ESR of 25 mΩ (measured at 100 kHz, 20 °C) and rated ripple current up to 1.45 A at 300 kHz (1.45 A HF) and 145 mA at 120 Hz.
• Thermal Endurance Operating temperature range –55 °C to 125 °C and a specified load life of 3000 hours at 125 °C under rated voltage.
• Assembly Compatibility Surface-mount radial can (SMD) designed for lead‑free reflow soldering with peak reflow temperature of 260 °C.
• Package & Mounting Compact size L: 5.7 × D: 6.3 mm with a recommended land pattern of 6.5 × 6.5 mm; polarized for correct orientation in circuits.
• Electrical Stability Leakage current specification: after 2 minutes' application of rated voltage leakage is not more than 0.3CV or 700 µA (whichever is greater), per datasheet conditioning notes.
• Environmental Compliance RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Point-of-load and DC–DC converter smoothing Low ESR and high ripple capability support output decoupling and hold-up in compact power modules.
• Power supply input/output filtering High ripple current rating across low- and high-frequency ranges helps manage switching and ripple currents in supply rails.
• High-density assemblies Small ϕ6.3 × 5.7 mm footprint and reflow compatibility enable automated placement in space-constrained, surface-mount designs.
• Elevated-temperature electronics 125 °C rating and 3000‑hour load life provide predictable performance in equipment exposed to sustained high temperatures.

Unique Advantages

• High ripple tolerance: Low ESR (25 mΩ at 100 kHz) combined with rated ripple currents up to 1.45 A at 300 kHz enables effective handling of switching currents in modern power stages.
• Compact, reflow-ready SMD package: Radial can SMD format and 260 °C lead‑free reflow compatibility simplify automated assembly in dense PCBs.
• Thermal reliability: Rated for –55 °C to 125 °C with a 3000‑hour life at 125 °C, offering endurance for applications with sustained elevated temperatures.
• Predictable leakage behavior: Datasheet leakage current limits (0.3CV or 700 µA after 2 minutes) support reliable bias and hold‑up calculations.
• Regulatory compliance: RoHS conformity aligns with environmental requirements for commercial and industrial electronics.
