RHS0J391MCN1GS

The RHS0J391MCN1GS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can designed for general-purpose electronic applications. It delivers 390 µF capacitance at a 6.3 V rating with low ESR and high ripple-current capability for demanding power-management tasks.

Key value drivers include a low ESR of 18 mΩ (100 kHz), high ripple-current ratings up to 3.2 A (300 kHz), and a documented load life of 2000 hours at 105°C, making it suitable where compact size and reliable thermal endurance are required.

Key Features

• Core Technology Conductive polymer aluminum solid electrolyte in a surface-mount radial can for stable electrical performance.
• Capacitance & Tolerance 390 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage 6.3 V working voltage.
• Low ESR Equivalent Series Resistance of 18 mΩ at 100 kHz (20°C) to minimize AC loss.
• High Ripple Current Rated ripple currents of 320 mA at 120 Hz and 3.2 A at 300 kHz for robust handling of AC stress.
• Reliability / Lifetime Endurance specified at 2000 hours at 105°C under rated voltage.
• Operating Temperature Range –55°C to +105°C to cover a wide range of thermal environments.
• Package & Mounting Surface-mount radial can, size L: 6.7 × D: 8 mm; recommended land size L: 8.3 × W: 8.3 mm.
• RoHS Compliant Meets RoHS directive requirements for lead-free production.

Typical Applications

• General-purpose electronic circuits Where 390 µF bulk capacitance in a compact SMD package is required.
• Power rail smoothing and decoupling Use in designs that benefit from low ESR (18 mΩ at 100 kHz) and high ripple current capability to stabilize supply voltages.
• High-frequency power systems Applicable in circuits that see ripple components up to 300 kHz, leveraging the capacitor’s specified high-frequency ripple rating.

Unique Advantages

• Low AC impedance: 18 mΩ ESR at 100 kHz reduces voltage ripple and improves transient response in power circuits.
• High ripple endurance: Rated for 320 mA at 120 Hz and 3.2 A at 300 kHz to tolerate sustained ripple currents.
• Compact SMD footprint: φ8 × 6.7 mm can and recommended land size of 8.3 × 8.3 mm enable space-efficient board layouts.
• Thermal endurance: 2000 hours at 105°C under rated voltage provides quantifiable reliability for thermal stress planning.
• Wide operating range: –55°C to +105°C supports diverse environmental conditions.
• RoHS-compliant supply chain: Conforms to RoHS requirements for lead-free manufacturing processes.
