PCJ1A391MCL1GS

The PCJ1A391MCL1GS is a conductive polymer aluminum solid electrolytic SMD capacitor designed for demanding power applications. It delivers 390 µF at 10 V with low equivalent series resistance and high ripple-current capability, targeting automotive and other high-reliability systems.

Built for robustness in elevated temperatures, this part is AEC-Q200 qualified, RoHS compliant and rated for 2000 hours of load life at 105°C, making it suitable for power filtering and decoupling in thermally stressful environments.

Key Features

• Capacitance and Voltage: 390 µF rated capacitance at 10 V provides bulk energy storage for power rails and hold-up functions.
• Low ESR: 17 mΩ ESR measured at 100 kHz reduces losses and improves voltage stability under dynamic load conditions.
• High Ripple Current: 4 A at 100 kHz and 2 A at 120 Hz support high-frequency switching and DC-DC converter outputs.
• Extended High‑Temperature Endurance: Load life of 2000 hours at 105°C; operating temperature range −55°C to +105°C for sustained thermal performance.
• Automotive Grade and Reliability: AEC‑Q200 qualification for designs requiring automotive-level component qualification.
• SMD Package and Reflow Capability: Chip-type SMD can with 8.3 × 8.3 mm recommended land size; compatible with lead‑free reflow soldering up to a 260°C peak.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Tolerance and Stability: Capacitance tolerance ±20% at 120 Hz, 20°C with documented post‑endurance limits for tan δ and ESR.

Typical Applications

• Automotive power systems: AEC‑Q200 qualification and high ripple capability make this capacitor suitable for smoothing and decoupling on automotive power rails and ECUs.
• DC‑DC converter output filtering: Low ESR and high ripple current rating support converter outputs and fast transient response in compact power modules.
• High‑temperature electronics: Rated for continuous operation and 2000‑hour load life at 105°C, ideal for electronics exposed to elevated ambient temperatures.

Unique Advantages

• High ripple tolerance: Supports up to 4 A at 100 kHz, enabling reliable operation with high-frequency switching sources.
• Low dissipation losses: 17 mΩ ESR minimizes I²R losses and thermal stress in dense power designs.
• Automotive‑grade assurance: AEC‑Q200 qualification provides documented reliability for vehicle electronics applications.
• Long high‑temperature life: 2000 hours at 105°C offers predictable end‑of‑life performance in elevated‑temperature environments.
• SMD form factor with reflow compatibility: Compact chip‑type can and lead‑free reflow capability simplify placement and assembly in automated manufacturing.
• Regulatory compliance: RoHS compliant for designs requiring restricted‑substance conformance.
