RDS0G391MCNAHFGS

The RDS0G391MCNAHFGS is a conductive polymer aluminum solid electrolytic capacitor in an SMD radial can (φ8×6.7 mm) offering 390 µF nominal capacitance at a 4 V rating. It combines high capacitance density with low ESR and high ripple capability for compact power and decoupling applications.

Key value propositions include high ripple-current handling, low equivalent series resistance (18 mΩ at 100 kHz), and extended load life (3000 hours at 125°C), all delivered in a surface-mount package compatible with lead-free reflow processing.

Key Features

• Capacitance & Rated Voltage — 390 µF nominal capacitance with a rated voltage of 4 V and a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Low ESR — 18 mΩ equivalent series resistance measured at 100 kHz, 20°C, supporting efficient power delivery and reduced ripple-induced heating.
• High Ripple Current — Rated ripple currents of 105 mA at 120 Hz (low frequency) and 1.05 A at 300 kHz (high frequency), suitable for demanding AC ripple conditions.
• Thermal Endurance — Load life specified at 3000 hours at 125°C under rated voltage, enabling stable performance in high-temperature environments.
• Loss Characteristics — tan δ specified at 0.12 (measured at 20°C, 120 Hz), enabling predictable dissipation performance.
• Leakage Current — Leakage current specified at 700 µA (after 2 minutes at 20°C), with conditioning test methods described in the datasheet.
• Surface-Mount Package — SMD radial can, size φ8 × 6.7 mm (case code HF), intended for surface mounting; packaged in embossed carrier taping with moisture-proof packing for automated assembly.
• Operating Temperature Range — −55°C to +125°C rated operating range for broad thermal environments.
• RoHS Compliance — Compliant with RoHS directive as stated in product data.

Unique Advantages

• High capacitance in a compact SMD can: 390 µF in a φ8×6.7 mm package reduces board area while providing bulk energy storage where space is limited.
• Lower ESR for improved power stability: 18 mΩ (100 kHz) helps minimize voltage drop and dissipated heat under AC ripple conditions.
• Robust ripple handling: High-frequency ripple rating of 1.05 A at 300 kHz supports demanding switching and power-conversion environments.
• Extended high-temperature life: Specified 3000-hour load life at 125°C offers predictable end-of-life performance for thermally stressed designs.
• Reflow-compatible SMD packaging: Designed for lead-free reflow processing (260°C peak correspondence in the series datasheet), simplifying automated assembly workflows.
• Moisture-proof taped packaging: Embossed carrier taping and moisture-proof packing support high-volume pick-and-place and storage handling.
