RHA0J391MCN1GS

The RHA0J391MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can (φ8) package designed for general-purpose electronic applications. It delivers high capacitance and low equivalent series resistance (ESR) in a compact SMD form factor, making it suitable where high ripple current handling and reliable operation at elevated temperatures are required.

Key value propositions include low ESR performance, high ripple-current capability, a rated voltage of 6.3 V, and a 2000-hour load life at 105°C. The device is compatible with lead-free reflow soldering (260°C peak) and is RoHS compliant.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with ±20% tolerance and a rated voltage of 6.3 V, providing substantial bulk storage in a compact package.
• Low ESR — ESR specified at 9 mΩ (100 kHz, 20°C), reducing impedance at high frequency for improved power stability.
• High Ripple Current — Rated ripple current of 450 mA at 120 Hz and 4.5 A at 300 kHz, supporting applications with significant AC ripple or switching activity.
• High-Temperature Endurance — Load life of 2000 hours at 105°C under rated voltage, with defined limits for capacitance change, tan δ and ESR after endurance testing.
• Wide Operating Range — Operating temperature range from –55°C to +105°C for broad environmental compatibility.
• Surface-Mount Can Package — Radial, can-style SMD (φ8×6.7 mm) with recommended land size L:8.3 × W:8.3 mm for automated assembly.
• Assembly & Compliance — Compatible with lead-free reflow soldering conditions (260°C peak correspondence) and RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized — Polarized capacitor suitable for DC filtering and bulk energy storage applications.

Typical Applications

• General-Purpose Electronics — Bulk capacitance and low ESR for smoothing and energy storage in a variety of board-level designs.
• High-Ripple Power Circuits — Supports circuits with significant ripple current thanks to 4.5 A rating at 300 kHz and high-frequency low ESR.
• Surface-Mount Assemblies — Compact φ8 can SMD package and 260°C lead-free reflow compatibility facilitate automated PCB assembly processes.

Unique Advantages

• High Capacitance in a Small Footprint: 390 µF in an 8×6.7 mm case provides substantial energy density for space-constrained designs.
• Low ESR for Improved Power Performance: 9 mΩ (100 kHz) helps lower impedance at switching frequencies and supports stable power delivery.
• Robust Ripple-Current Handling: Rated ripple current up to 4.5 A at 300 kHz addresses demanding switching and filtering applications.
• Designed for Elevated Temperatures: 2000-hour load life at 105°C gives predictable endurance in high-temperature environments.
• Assembly-Friendly: Surface-mount radial can package with defined land pattern and lead-free reflow compatibility simplifies manufacturing.
• Regulatory Compliance: RoHS compliant to the cited directives for environmentally conscious designs.
