PCJ0J391MCL1GS

The PCJ0J391MCL1GS is a Nichicon conductive-polymer aluminum solid electrolytic capacitor in an SMD can package, offering 390 µF capacitance at a 6.3 V rating. It is designed for applications demanding low ESR, high ripple-current handling and extended load life in challenging thermal environments.

Targeted for automotive and industrial electronics, the PCJ series combines high capacitance density with AEC-Q200 qualification and RoHS compliance to address reliability and manufacturability needs in surface-mount assemblies.

Key Features

• Electrical Performance — 390 µF capacitance at 6.3 V with ±20% tolerance; low ESR specified as 14 mΩ at 100 kHz for improved filtering and decoupling.
• High Ripple Current — Rated ripple currents of 1.975 A at 120 Hz and 3.95 A at 100 kHz enable robust AC and switching-power applications.
• Reliability & Lifetime — Load life of 2000 hours at 105°C with defined endurance limits for capacitance, tan δ and ESR after life test.
• Thermal & Soldering Robustness — Operation from −55°C to +105°C; designed for lead-free reflow soldering with peak profile correspondence up to 260°C (single reflow) and defined soldering-heat resistance limits in the datasheet.
• Package & Mounting — Chip-type can SMD package (L: 7 × D: 8 mm) with recommended land size 8.3 × 8.3 mm; polarized construction for correct orientation on PCB.
• Standards & Compliance — AEC-Q200 qualified and compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and extended temperature range make this capacitor suitable for automotive electronic modules requiring reliable smoothing and decoupling.
• Power Rail Decoupling — High capacitance (390 µF) and low ESR (14 mΩ at 100 kHz) support stable voltage rails and transient suppression on DC power lines.
• High-Frequency Power Systems — Rated ripple current at 100 kHz (3.95 A) addresses the needs of switching regulators and high-frequency converters.
• Surface-Mount Production — SMD chip can package and defined lead-free reflow compatibility (up to 260°C peak under specified conditions) enable standard SMT assembly processes.

Unique Advantages

• Low ESR for improved transient response: 14 mΩ (100 kHz) ESR helps reduce voltage ripple and improves performance in high-current switching environments.
• High ripple-current capability: Specified ripple currents at both 120 Hz and 100 kHz extend usable life in AC and switching applications.
• Extended high-temperature endurance: 2000-hour load life at 105°C provides a measurable reliability baseline for long-term high-temperature use.
• Automotive-grade qualification: AEC-Q200 status supports use in applications requiring industry-recognized component qualification.
• Manufacturing-ready package: Chip-type SMD can with defined land pattern simplifies PCB layout and supports lead-free reflow assembly flows.
• Regulatory compliance: RoHS conformity ensures the part meets common environmental requirements for commercial and industrial designs.
