RDS1C221MCNAHFGS

The RDS1C221MCNAHFGS is a surface-mount conductive polymer aluminum electrolytic capacitor delivering 220 µF at 16 V in a compact φ8 × 6.7 mm can-style SMD package. Engineered for high-capacitance, high-ripple environments, it provides low ESR and extended endurance for demanding power electronics applications.

Key attributes include a wide operating temperature range (−55 °C to +125 °C), a rated load life of 3000 hours at 125 °C, and compatibility with lead-free reflow soldering (260 °C peak). RoHS-compliant packaging is supplied in embossed carrier tape with moisture-proof protection.

Key Features

• Capacitance and Voltage — 220 µF rated capacitance with ±20% tolerance at a rated voltage of 16 V.
• Conductive-Polymer Construction — Solid electrolyte design for stable electrical characteristics and high ripple handling.
• Low ESR — Equivalent series resistance of 23 mΩ measured at 100 kHz, 20 °C, which minimizes losses in high-frequency circuits.
• High Ripple Current — Rated ripple current of 180 mA at 120 Hz and up to 1.8 A at 300 kHz, enabling use with high-frequency switching supplies.
• Wide Temperature Range — Specified for operation from −55 °C to +125 °C, with endurance tested to 3000 hours at 125 °C.
• Leakage Current — Typical leakage current specified as 1056 µA (measured after standard conditioning).
• Compact SMD Can — Case size φ8 × 6.7 mm (size code HF) with surface-mount land recommendation of 8.3 × 8.3 mm for PCB layout.
• Reflow and RoHS — Compatible with lead-free reflow soldering (260 °C peak) and compliant with RoHS requirements.
• Packaging — Supplied in embossed carrier tape with moisture-proof packing for automated assembly.

Typical Applications

• Power supply decoupling — Bulk and high-frequency decoupling to stabilize DC rails in switching regulators and module outputs, leveraging low ESR and high ripple capability.
• DC–DC converters — Energy smoothing and output filtering for converters operating at high switching frequencies up to the 100–300 kHz range.
• Embedded and industrial electronics — Reliable capacitance in compact SMD form for controllers, power modules, and industrial electronics requiring extended high-temperature endurance.

Unique Advantages

• High ripple tolerance: Rated for up to 1.8 A at 300 kHz, allowing designers to handle high-frequency switching currents without excessive heating.
• Long high-temperature life: 3000 hours at 125 °C provides predictable endurance for designs exposed to prolonged elevated temperatures.
• Low-loss operation: 23 mΩ ESR at 100 kHz reduces I²R losses and improves regulator efficiency in high-current paths.
• Compact SMD form factor: φ8 × 6.7 mm package saves PCB area while providing substantial capacitance for space-constrained designs.
• Assembly-ready packaging: Embossed carrier tape with moisture-proof packing supports automated placement and consistent reflow performance.
• Regulatory compliance: RoHS conformity and lead-free reflow compatibility simplify compliance and manufacturing process integration.
