RSA0G391MCN1GS

The RSA0G391MCN1GS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can (φ6.3 × 5.7 mm) designed for general-purpose applications. It combines high capacitance (390 µF) and low ESR to support compact SMD designs that require robust ripple handling and long endurance at elevated temperatures.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 4 V rated voltage and ±20% tolerance, delivering substantial bulk capacitance in a small SMD can (φ6.3 × 5.7 mm).
• Low ESR & High Ripple Capability — ESR of 14 mΩ measured at 20°C/100 kHz and a high-frequency ripple current rating of 3.16 A (300 kHz) enable effective AC handling and decoupling performance.
• Wide Frequency Ripple Performance — Ripple current coefficients across frequency support performance from low (120 Hz, 316 mA) to high frequencies (300 kHz, 3.16 A), providing predictable behavior across common switching and filtering bands.
• Thermal Endurance — Rated for operation from −55°C to 105°C with a rated load life of 2000 hours at 105°C, offering endurance for prolonged elevated-temperature use.
• Leakage & Loss Characteristics — Specified leakage current of 700 µA and tan δ of 0.12 (measured at 20°C, 120 Hz) for controlled loss behavior in DC and AC conditions.
• Surface-Mount Packaging — Available in embossed carrier taping with moisture-proof packing for automated SMD assembly and reflow processes.
• RoHS Compliant — Conforms to RoHS requirements as specified in the product data.

Typical Applications

• General-purpose surface-mount circuits — Use where a 390 µF, 4 V polarized SMD capacitor is required for board-level bulk capacitance and energy storage.
• High-frequency decoupling — Employ to handle high-frequency ripple currents up to 3.16 A (300 kHz) while maintaining low ESR (14 mΩ @100 kHz).
• Compact electronic assemblies — Ideal for space-constrained designs needing high capacitance in a φ6.3 × 5.7 mm SMD can with embossed carrier taping for pick-and-place.

Unique Advantages

• High capacitance in a small SMD footprint: 390 µF in a φ6.3 × 5.7 mm package reduces board area for bulk energy storage needs.
• Low ESR for efficient AC performance: 14 mΩ (20°C/100 kHz) minimizes losses and supports higher ripple currents, improving thermal and electrical efficiency.
• Broad ripple-current capability: Ratings from 316 mA (120 Hz) to 3.16 A (300 kHz) provide predictable performance across switching and filtering frequencies.
• Designed for elevated-temperature endurance: 2000 hours at 105°C supports longer operating life in thermally demanding environments.
• Manufacturing-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated assembly and storage.
• Regulatory compliance: RoHS conformity simplifies integration into compliant products.
