PCF1D390MCL1GS

The PCF1D390MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It delivers 39 µF at 20 V with low ESR and high ripple-current capability designed for demanding electronic power applications.

Engineered for robust operation across –55°C to 105°C and qualified to AEC‑Q200, this SMD capacitor targets automotive and other high-reliability markets that require compact, high-performance decoupling and bulk storage in tight PCB layouts.

Key Features

• Capacitance and Voltage — 39 µF rated capacitance with a 20 V rated voltage and a capacitance tolerance of ±20% (–20%~20%).
• Low Loss and Stability — Tangent of loss angle (tan δ) of 0.12 measured at 20°C, 120 Hz, supporting stable AC performance under typical measurement conditions.
• Low ESR and High Ripple Current — ESR of 45 mΩ at 20°C/100 kHz, with low-frequency ripple current of 1 A (120 Hz) and high-frequency ripple current of 2 A (100 kHz) for efficient handling of switching and high-frequency loads.
• Reliability and Endurance — Load life rated at 2000 hours at 105°C with specified endurance limits for capacitance, tan δ and ESR; leakage current specified at 156 µA.
• Automotive Qualified — AEC‑Q200 rating and explicit application for automotive environments, plus RoHS compliance for regulatory assurance.
• Surface-Mount, Compact Package — Radial can SMD package with dimensions φ8 × 7 mm (L: 7 × D: 8 mm) and recommended land size 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing for assembly.
• Reflow Compatibility — SMD type supports lead-free reflow soldering conditions with peak temperatures up to 260°C as specified for the series.

Typical Applications

• Automotive power electronics — Suited for power rail decoupling and energy smoothing in automotive modules where AEC‑Q200 qualification and high ripple handling are required.
• DC–DC converters — Low ESR (45 mΩ) and 2 A high-frequency ripple current capability make this capacitor appropriate for output filtering in switched-mode power supplies.
• Infotainment and control units — Compact φ8 × 7 mm SMD packaging and robust temperature range (–55°C to 105°C) enable use in compact onboard electronics and control modules.

Unique Advantages

• High ripple tolerance: 2 A at 100 kHz high-frequency ripple current and 1 A at 120 Hz reduce stress on the capacitor in switching environments.
• Low ESR for efficient power delivery: 45 mΩ ESR at 100 kHz lowers power loss and improves transient response for power rails.
• Automotive-grade reliability: AEC‑Q200 qualification and a 2000-hour life at 105°C provide predictable endurance for vehicle electronics.
• Compact SMD can package: φ8 × 7 mm radial can SMD format enables high-density PCB designs while maintaining axial robustness.
• Manufacturing-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated placement and assembly processes.
