PCJ1C390MCL1GS

The PCJ1C390MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor from Nichicon's PCJ series. It delivers low ESR and higher capacitance in a compact surface-mount can package, optimized for applications that require high ripple handling and elevated temperature endurance.

Designed for automotive applications and engineered for surface-mount assembly, this part combines a 39 µF capacitance at 16 V with AEC-Q200 qualification, RoHS compliance, and a 2000-hour load life at 105°C for reliable performance in demanding environments.

Key Features

• Capacitance & Rated Voltage — 39 µF rated at 16 V with ±20% tolerance at 120 Hz, 20°C.
• Low ESR — 35 mΩ equivalent series resistance measured at 100 kHz, supporting fast transient response and reduced dissipation.
• High Ripple Current — 1.035 A at 120 Hz and 2.07 A at 100 kHz, enabling effective ripple filtering in power rails.
• High-Temperature Endurance — Load life of 2000 hours at 105°C; operating temperature range −55°C to +105°C.
• AEC-Q200 Qualified — Specified for automotive-grade reliability (AEC-Q200).
• SMD Assembly Compatible — Chip-type, can-style SMD compatible with lead‑free reflow soldering (peak correspondence up to 260°C).
• Compact Package — Case dimensions L × D: 6 × 5 mm; surface-mount land size L × W: 5.3 × 5.3 mm for tight PCB layouts.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power supply filtering — Low ESR and high ripple current ratings make this capacitor suitable for smoothing and decoupling on automotive DC power rails.
• Control module electronics — AEC-Q200 qualification and 2000-hour load life at 105°C address reliability needs for control units and modules operating at elevated temperatures.
• Compact SMD designs — The 6 × 5 mm can-style chip fits compact PCBs where board space and high-performance decoupling are required.

Unique Advantages

• Low ESR for improved transient performance: 35 mΩ at 100 kHz reduces voltage ripple and power loss in high-frequency circuits.
• High ripple-handling capability: Rated ripple currents of 1.035 A (120 Hz) and 2.07 A (100 kHz) support demanding power-conditioning tasks.
• High-temperature reliability: 2000-hour load life at 105°C and an operating range of −55°C to +105°C enable long-term operation in harsh thermal environments.
• Automotive-grade qualification: AEC-Q200 rating provides documented suitability for automotive electronics applications.
• SMD-friendly package and assembly: Compact 6 × 5 mm chip can with lead‑free reflow compatibility up to 260°C simplifies automated board assembly.
• Standards compliance: RoHS conformity supports regulatory requirements for lead-free designs.
