RSB0J221MCN1GS

The RSB0J221MCN1GS is a conductive polymer aluminum solid electrolytic surface-mount capacitor delivering 220 µF at a rated voltage of 6.3 V. It combines low equivalent series resistance with high ripple-current capability in a compact φ6.3 × 5.7 mm SMD can.

Engineered for general-purpose electronic applications, this part provides stable capacitance across a wide temperature range and extended endurance for demanding power-decoupling and smoothing tasks.

Key Features

• Capacitance and Tolerance — 220 µF nominal capacitance with tolerance of -20%~20% (measured at 120 Hz, 20°C).
• Rated Voltage — 6.3 V working voltage suitable for low-voltage power rails and decoupling use cases.
• Low ESR — ESR of 12 mΩ measured at 20°C / 100 kHz, supporting low-loss operation at high switching frequencies.
• High Ripple Current Capability — Low-frequency ripple current 350 mA (120 Hz) and high-frequency ripple current 3.5 A (300 kHz) to handle both bulk and high-frequency ripple demands.
• Dielectric and Loss — Conductive polymer dielectric with tanδ (DF) of 0.12 at 20°C / 120 Hz for predictable dissipation behavior.
• Reliability and Lifetime — Rated life of 2000 hours at 105°C under rated voltage conditions, with endurance limits defined for capacitance, tanδ and ESR.
• Operating Temperature Range — −55°C to 105°C for broad environmental tolerance.
• Compact SMD Package — φ6.3 × 5.7 mm can (package case: radial, can - SMD) with embossed carrier taping and moisture-proof packing for automated assembly.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• General-purpose electronics — Bulk decoupling and stabilization on low-voltage boards where a compact, high-capacitance SMD solution is required.
• Power-supply smoothing — Low ESR and high ripple-current capability make this part suitable for smoothing outputs of switching regulators and DC–DC converters.
• High-frequency decoupling — 12 mΩ ESR at 100 kHz and 3.5 A ripple current at 300 kHz support high-frequency transient filtering near switching components.

Unique Advantages

• Low-loss performance: 12 mΩ ESR at 100 kHz and tanδ 0.12 reduce dissipation and temperature rise in high-frequency circuits.
• High ripple endurance: Rated ripple currents of 350 mA (120 Hz) and 3.5 A (300 kHz) allow handling both mains-frequency and switching-frequency ripple without excessive heating.
• Compact SMD footprint: φ6.3 × 5.7 mm package saves board space while providing 220 µF of capacitance for dense designs.
• Wide temperature range: −55°C to 105°C operation supports robust performance across varied environmental conditions.
• Long rated life at elevated temperature: 2000 hours at 105°C under rated voltage provides design confidence for continuous-duty applications.
• RoHS compliance: Meets environmental directives for restricted substances in electronic assemblies.
