RSA1C221MCN1GS

The RSA1C221MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount radial can (φ6.3×7.7 mm). It delivers 220 µF capacitance at 16 V with low ESR and high ripple-current capability for space-constrained power designs.

Engineered for general-purpose applications, this SMD capacitor targets designs that require high capacitance density, reliable operation across –55 °C to 105 °C, and endurance under elevated temperatures (2000 hours at 105 °C).

Key Features

• Core Electrical Performance  220 µF capacitance with ±20% tolerance and a tangent of loss angle (tanδ) of 0.12 measured at 20 °C, 120 Hz, providing predictable AC behavior.
• Low ESR and High Ripple Handling  ESR of 20 mΩ at 20 °C/100 kHz combined with a high-frequency ripple current rating of 3.5 A (300 kHz) and 350 mA at 120 Hz, enabling effective smoothing and decoupling in switching environments.
• Temperature and Endurance  Operating temperature range from –55 °C to 105 °C and a rated life of 2000 hours at 105 °C for reliable performance in elevated-temperature applications.
• Surface-Mount Packaging  Radial can SMD package sized φ6.3 × 7.7 mm with prescribed surface-mount land size (6.5 × 6.5 mm) and supplied in embossed carrier taping with moisture-proof packing for pick-and-place assembly.
• Leakage and Stability  Rated leakage current 704 µA (specified condition) and endurance limits defined for capacitance change, tanδ, and ESR over the lifetime test.
• Compliance  RoHS compliant.

Typical Applications

• General-purpose power filtering  Provides bulk capacitance and low impedance at high frequency to smooth DC rails in compact power supplies and modules.
• Switching regulator decoupling  Low ESR and high ripple-current capability support decoupling near DC-DC converters and switching components.
• Power module integration  Compact φ6.3×7.7 mm SMD can for designs that require high capacitance density while maintaining assembly-friendly carrier taping.

Unique Advantages

• High capacitance in a small SMD can  220 µF in a φ6.3 × 7.7 mm package saves board area compared with larger through-hole parts.
• Low impedance at high frequency  20 mΩ ESR at 100 kHz helps reduce output ripple and improves transient response when placed close to switching elements.
• Robust ripple-current rating  3.5 A at 300 kHz supports modern switching frequencies and reduces heating under AC loading.
• Long elevated-temperature life  2000 hours at 105 °C gives predictable endurance for designs exposed to high operating temperatures.
• Assembly-ready packaging  Embossed carrier taping and moisture-proof packing streamline automatic placement and handling.
• Regulatory compliance  RoHS-compliant materials for regulated production environments.
