PCM1H390MCL4GS

The PCM1H390MCL4GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD radial can package. It delivers low ESR and high ripple-current capability in a compact surface-mount form factor.

Designed for high-temperature, high-reliability applications—including automotive electronics—this part offers a wide operating temperature range and long-term endurance, together with lead‑free reflow compatibility for modern assembly flows.

Key Features

• Dielectric & Type  Conductive polymer aluminum solid electrolytic capacitor, chip type; polarized.
• Capacitance & Voltage  39 µF rated capacitance with 50 V rated voltage and ±20% tolerance (at 120 Hz, 20°C).
• Low ESR  36 mΩ equivalent series resistance measured at 100 kHz, 20°C for efficient filtering and low loss.
• High Ripple Current  Handles 1.2 A at 100 kHz (high frequency) and 600 mA at 120 Hz (low frequency) for demanding power applications.
• High-Temperature Performance  Operating temperature range −55°C to +125°C with rated endurance of 6000 hours at 125°C for sustained reliability in hot environments.
• Automotive Qualification  AEC‑Q200 qualified, supporting use in automotive-grade electronic designs.
• Reflow & Assembly  SMD type designed for lead‑free reflow soldering; compatible with 260°C peak reflow profiles.
• Package & Footprint  Compact radial can SMD: L 8 × D 6.3 mm; recommended land size L 6.6 × W 6.6 mm for surface-mount assembly.
• Environmental Compliance  RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronic modules  Use in automotive ECUs and power modules where AEC‑Q200 qualification, −55°C to +125°C range, and long endurance are required.
• Power supply decoupling and filtering  Ideal for decoupling and smoothing in power converters and regulators thanks to low ESR (36 mΩ) and high ripple-current capability (up to 1.2 A at 100 kHz).
• High-temperature electronics  Suited to electronics exposed to elevated operating temperatures because of 125°C rating and reflow compatibility with 260°C peak profiles.

Unique Advantages

• Reliable high-temperature endurance: 6000 hours at 125°C rated life supports long-term operation in hot environments.
• Low-loss performance: 36 mΩ ESR at 100 kHz reduces dissipation and improves power-stage efficiency.
• High ripple-current handling: 1.2 A at 100 kHz and 600 mA at 120 Hz enable robust performance in switching power applications.
• Automotive-grade qualification: AEC‑Q200 qualification provides confidence for automotive system integration.
• Surface-mount assembly ready: Compact radial can SMD and 260°C lead‑free reflow compatibility streamline modern PCB assembly processes.
• Regulatory compliance: RoHS conformity supports environmentally driven design requirements.
