RSA0G331MCN1GS

The RSA0G331MCN1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RSA series. It delivers 330 µF capacitance at a 4 V rating in a compact φ6.3×5.7 mm SMD can suitable for space-constrained designs.

Engineered for general-purpose electronic applications, this part combines low ESR and high ripple-current capability with a wide operating temperature range and a 2000-hour endurance at 105°C, providing a reliable bulk-capacitance option for power delivery and decoupling needs.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with tolerance of -20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 4 V (surge voltage 4.6 V as documented for the series).
• Low ESR & High Ripple Capability — ESR of 14 mΩ measured at 20°C/100 kHz and rated ripple current up to 3.16 A (300 kHz) supporting high AC stress on power rails; ripple current at 120 Hz is 316 mA.
• Loss Tangent — tanδ = 0.12 (measured at 20°C, 120 Hz), for predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 700 µA (after 2 minutes at 20°C under rated voltage conditions defined in the datasheet).
• Temperature & Endurance — Operating range −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Compact SMD Package — φ6.3×5.7 mm case size, radial can SMD construction; recommended land size 6.5 × 6.5 mm.
• Manufacturing Compatibility — SMD type with lead‑free reflow soldering condition correspondence (260°C peak) as specified for the series.
• RoHS Compliant — Meets RoHS requirements as stated for the RSA series.

Typical Applications

• General-purpose power supply decoupling — Provides bulk capacitance and low ESR to stabilize low-voltage power rails in compact electronic assemblies.
• Compact SMD designs — Small φ6.3×5.7 mm footprint suited to space-constrained PCBs requiring surface-mount bulk capacitors.
• High ripple-current circuits — Suitable where elevated AC ripple is present, leveraging the 3.16 A (300 kHz) rated ripple capability and low ESR for improved thermal and electrical performance.
• Elevated-temperature operation — Appropriate for applications that require continuous operation within −55°C to +105°C and a 2000-hour endurance at 105°C.

Unique Advantages

• High bulk capacitance in a small package: 330 µF in a φ6.3×5.7 mm SMD can reduces board area while maintaining needed energy storage.
• Low ESR for improved transient response: 14 mΩ ESR at 100 kHz supports fast load transients and reduces voltage droop on power rails.
• Strong ripple-current handling: Rated for up to 3.16 A at high frequency (300 kHz), enabling reliable operation under heavy AC stress.
• Designed for elevated-temperature endurance: 2000 hours at 105°C provides a verified life metric for thermal reliability planning.
• Assembly-ready SMD form factor: Surface-mount can and lead‑free reflow compatibility simplify automated assembly for compact product designs.
• Regulatory compliance: RoHS status documented for environmental compliance in manufacturing and supply chains.
