PCK0J391MCO1GS

The PCK0J391MCO1GS is a Nichicon conductive polymer aluminum solid electrolytic capacitor in a chip-style SMD package. It delivers ultra-low ESR, higher capacitance (390 µF) and high ripple current capability for demanding power applications.

Designed and qualified for robust operation, this part supports a rated voltage of 6.3 V, an operating temperature range of –55 °C to +105 °C, AEC-Q200 qualification, RoHS compliance, and a rated load life of 2000 hours at 105 °C. It is suitable for applications that require high ripple handling and stable performance in harsh environments.

Key Features

• Capacitance and Voltage — 390 µF capacitance at a rated voltage of 6.3 V with ±20% tolerance, providing bulk energy storage in compact SMD form.
• Ultra-low ESR — ESR of 9 mΩ measured at 100 kHz (20 °C) to reduce conduction losses and improve transient response on power rails.
• High ripple current — Rated ripple currents of 2.25 A at 20 Hz and 4.5 A at 100 kHz to support high-frequency and low-frequency ripple environments.
• Temperature and Endurance — Operating range from –55 °C to +105 °C with a specified load life of 2000 hours at 105 °C, maintaining capacitance and ESR within defined endurance limits.
• SMD, Lead-free Reflow Compatible — Chip-type surface-mount package with lead-free reflow soldering compatibility up to a 260 °C peak (single reflow at 260 °C), and defined soldering profiles in the datasheet.
• Automotive Qualification and Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), suitable for regulated environments requiring these certifications.
• Compact Package — Package dimensions L: 7 × D: 8 mm, height seated max 7 mm, and recommended PCB land size L: 8.3 × W: 8.3 mm for surface-mount assembly.
• Polarized Device — Polarized electrolytic construction for DC power applications; follow polarity guidance during layout and assembly.

Typical Applications

• Automotive power rails — Provides bulk decoupling and ripple smoothing on automotive DC-DC converter outputs and supply rails, leveraging AEC-Q200 qualification and high ripple current capability.
• Power-supply filtering — Suited for input/output filtering on voltage regulators and power modules where low ESR and high ripple current improve stability and efficiency.
• High-frequency power stages — Effective in high-frequency switching environments due to 9 mΩ ESR at 100 kHz and rated ripple current at 100 kHz.

Unique Advantages

• Low loss operation: 9 mΩ ESR at 100 kHz minimizes I²R losses and heat generation in power-dense designs.
• High ripple tolerance: Rated ripple currents (2.25 A at 20 Hz, 4.5 A at 100 kHz) allow the capacitor to handle both low- and high-frequency ripple without compromising performance.
• Robust thermal endurance: 2000-hour load life at 105 °C provides predictable long-term behavior in elevated-temperature environments.
• Automotive-ready qualification: AEC-Q200 qualification offers traceable suitability for automotive and similarly demanding applications.
• SMD assembly compatibility: Chip-style package and defined lead-free reflow profile (260 °C peak correspondence) simplify surface-mount production processes.
