RDS0J391MCNAHFGS

The RDS0J391MCNAHFGS is a conductive polymer aluminum solid electrolytic capacitor in a compact SMD radial-can package. It delivers high capacitance (390 µF) at a rated voltage of 6.3 V with low ESR and high ripple-current capability for board-level power applications.

Designed for elevated operating temperatures, this part offers a rated temperature range of –55 °C to +125 °C, a load life of 3000 hours at 125 °C, and compatibility with lead-free reflow processes up to a 260 °C peak.

Key Features

• Dielectric / Core Conductive polymer aluminum solid electrolytic construction for stable high-capacitance performance.
• Electrical 390 µF capacitance at 6.3 V with ±20% tolerance; ESR specified at 18 mΩ (100 kHz, 20 °C) to support low-loss operation.
• Ripple Current High ripple capability: 205 mA at 120 Hz and 2.05 A at 300 kHz, enabling effective handling of switching and high-frequency currents.
• Temperature & Endurance Rated for –55 °C to +125 °C with a demonstrated load life of 3000 hours at 125 °C under rated voltage.
• Package & Assembly Surface-mount radial can (size code HF: φ8 × L 6.7 mm, seated height 6.7 mm); compatible with lead-free reflow soldering conditions (260 °C peak).
• Regulatory Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling and bulk smoothing Low ESR and high ripple current capability make this capacitor suitable for smoothing and decoupling in switching power supplies and regulators.
• High-temperature electronics Use on boards that require sustained operation up to 125 °C and exposure to lead-free reflow assembly temperatures.
• Compact SMD power modules The radial-can SMD package (8 × 6.7 mm) provides high capacitance in a small footprint for compact power and point-of-load designs.

Unique Advantages

• High capacitance density: 390 µF in an 8 × 6.7 mm package reduces board area compared with multiple discrete capacitors.
• Low ESR at high frequency: 18 mΩ (100 kHz) helps reduce conduction losses and heat generation in high-frequency switching applications.
• Designed for elevated-temperature endurance: 3000-hour load life at 125 °C provides predictable long-term performance in hot operating environments.
• Assembly-friendly SMD format: Compatible with lead-free reflow up to 260 °C, enabling streamlined manufacturing on surface-mount processes.
• Regulatory compliance: RoHS conformity supports use in designs targeting restricted-substance compliance.
