RDS0G221MCNAHFGS

The RDS0G221MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor delivering 220 µF at 4 V with a polarized design. Engineered for compact SMD assemblies, it combines high capacitance and high ripple-current capability with robust thermal endurance for elevated-temperature operation.

Key differentiators include a long load life rating of 3000 hours at 125°C, low ESR at high frequency, and compatibility with lead-free reflow processes up to a 260°C peak. These characteristics make it suited for designs where sustained performance at higher operating temperatures and compact board space are required.

Key Features

• Dielectric / Core Conductive polymer aluminum solid electrolytic construction for high capacitance density in an SMD package.
• Capacitance & Voltage 220 µF nominal capacitance at a rated voltage of 4 V with ±20% tolerance (120 Hz, 20°C).
• Thermal Endurance Rated operating temperature range −55°C to 125°C and a specified load life of 3000 hours at 125°C.
• Low ESR and Ripple Performance ESR 18 mΩ measured at 100 kHz (20°C) and rated ripple current up to 1.05 A at 300 kHz (with lower-frequency coefficient data available for system-level ripple calculations).
• SMD Package and Reflow Surface-mount radial can (SMD) with case size 8 × 6.7 mm (L × D). Compatible with lead-free reflow soldering conditions up to a 260°C peak.
• Reliability & Compliance Polarized capacitor with specified leakage current limits and RoHS compliance (2011/65/EU, (EU)2015/863).
• Board Footprint Compact footprint with recommended land pattern dimensions of 8.3 × 8.3 mm for reliable mounting and solder fillet formation.

Typical Applications

• Elevated-temperature SMD assemblies — Use where components are required to operate reliably at temperatures up to 125°C and survive lead‑free reflow at 260°C.
• High-ripple-current circuits — Suitable for SMD designs that require capacitors with low ESR and high ripple-current capability at high frequencies.
• Compact power modules — Fits tight board spaces needing high capacitance in a small can-type SMD package (8 × 6.7 mm).

Unique Advantages

• Long high-temperature life: Rated 3000 hours at 125°C, enabling extended endurance in thermally demanding applications.
• Low high-frequency ESR: 18 mΩ at 100 kHz (20°C) improves filtering and reduces loss in high-frequency power circuits.
• Strong ripple handling: Rated ripple current up to 1.05 A at 300 kHz supports high-frequency decoupling and bulk filtering needs.
• Reflow-ready SMD form factor: Lead-free reflow compatible to a 260°C peak for modern assembly workflows.
• RoHS compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for environmental and regulatory alignment.
• Compact footprint: 8 × 6.7 mm case size with a recommended land size of 8.3 × 8.3 mm for space-constrained PCB designs.
