PCJ0E391MCL1GS

The PCJ0E391MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount power-decoupling and energy-storage applications. It combines a high 390 µF capacitance with low ESR to support high ripple currents in compact SMD layouts.

Built for demanding environments, this part offers a wide operating temperature range of −55 °C to 105 °C, a 2000‑hour load life at 105 °C, RoHS compliance, and AEC‑Q200 qualification for automotive-grade designs.

Key Features

• Dielectric / Construction: Conductive polymer aluminum solid electrolytic, chip type for surface-mount integration and reliable polarized operation.
• Capacitance & Voltage: 390 µF rated capacitance with a 2.5 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low ESR / High Ripple Handling: ESR of 15 mΩ measured at 100 kHz (20 °C), with ripple current ratings of 1.7 A at 120 Hz and 3.4 A at 100 kHz to support power-regulation and decoupling tasks.
• Thermal & Endurance Performance: Operating temperature range −55 °C to 105 °C and a load life specified at 2000 hours at 105 °C; endurance limits for capacitance, tan δ and ESR are defined by the product specification.
• Soldering / Assembly: SMD type compatible with lead-free reflow; peak reflow correspondence up to 260 °C per product specifications for standard surface-mount assembly.
• Size & Mounting: Compact chip package with dimensions L: 6 × D: 6.3 mm and recommended land pattern L: 6.6 × W: 6.6 mm for surface-mount placement.
• Compliance & Qualification: RoHS compliant and AEC‑Q200 qualified for applications requiring recognized component-level reliability.

Typical Applications

• Automotive power modules: Decoupling and bulk storage on low-voltage rails where AEC‑Q200 qualification and a 2000‑hour 105 °C load life are required.
• DC‑DC converters and point-of-load regulation: Low ESR and high ripple-current capability support tight voltage regulation and transient response.
• Compact SMD power electronics: High capacitance in a small chip package enables space-efficient smoothing and energy buffering on crowded boards.

Unique Advantages

• High capacitance in a compact chip: 390 µF in a 6 × 6.3 mm footprint reduces board area compared with larger can-style capacitors.
• Low ESR for efficient power handling: 15 mΩ at 100 kHz minimizes losses and supports higher ripple currents for improved thermal performance.
• Automotive-grade qualification: AEC‑Q200 qualification provides traceable component-level reliability for vehicle electronics and other harsh environments.
• Extended high-temperature endurance: 2000‑hour load life at 105 °C delivers predictable long-term behavior in high-temperature applications.
• Assembly-ready SMD form factor: Designed for lead-free reflow processes (260 °C peak correspondence), simplifying integration into modern SMT production flows.
