RSA0J331MCN1GS

The RSA0J331MCN1GS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RSA series. It delivers 330 µF of capacitance at a 6.3 V rating in a compact φ6.3×5.7 mm SMD can, aimed at general-purpose electronic designs that require high capacitance density and robust ripple handling.

Designed for reliability in elevated-temperature environments, this part combines low ESR and high ripple current capability with a -55°C to 105°C operating range and a 2000 hour life at 105°C, making it suitable for demanding board-level power applications within its specified limits.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of -20% to +20%.
• Low ESR — Equivalent series resistance of 14 mΩ measured at 20°C/100 kHz for improved high-frequency performance.
• High Ripple Current — Rated ripple current up to 3160 mA (3.16 A) at 105°C/100 kHz and specified lower-frequency ripple current of 316 mA at 120 Hz.
• Loss Tangent — tan δ = 0.12 (measured at 20°C, 120 Hz), supporting efficient energy handling and stable AC behavior.
• Leakage Current — Specified leakage current of 700 µA (after 2 minutes at 20°C), supporting predictable DC behavior in designs.
• Reliability & Endurance — Load life of 2000 hours at 105°C under rated voltage; capacitance, tan δ and ESR limits are specified for endurance verification.
• Temperature Range — Wide operating range from -55°C to +105°C for use across varied thermal environments.
• Compact SMD Package — φ6.3×5.7 mm radial can SMD with surface-mount land size of 6.5 × 6.5 mm; shipped in embossed carrier taping with moisture-proof packing for automated assembly.
• Regulatory Compliance — RoHS compliant.
• Polarized — Polarized capacitor intended for appropriate polarized circuit placement.

Typical Applications

• General-purpose electronics — Provides high capacitance in a compact SMD can for board-level bulk capacitance and energy storage in general-purpose designs.
• High-frequency power circuits — Low ESR (14 mΩ at 100 kHz) and rated ripple current (3.16 A at 100 kHz) help manage AC ripple and switching losses in high-frequency applications.
• Thermally demanding assemblies — 2000 hour endurance at 105°C and a -55°C to 105°C operating range support reliability in elevated-temperature environments.

Unique Advantages

• High capacitance in a compact SMD — 330 µF in a φ6.3×5.7 mm package reduces board area for bulk energy storage compared with larger through-hole parts.
• Strong AC performance — Low ESR and a high rated ripple current (3.16 A at 105°C/100 kHz) enable effective handling of switching and ripple currents in power circuits.
• Predictable electrical behavior — Specified tan δ (0.12) and leakage current (700 µA) provide measurable parameters for design verification and stability analysis.
• Robust thermal endurance — 2000 hours at 105°C rated life supports long-term reliability where elevated temperatures are expected.
• Assembly-ready packaging — Embossed carrier taping and moisture-proof packing support automated SMD placement and handling.
• Manufacturer backing — Nichicon RSA series with mass production availability and documented specifications for engineering validation.
