PCF1A331MCL4GS

The PCF1A331MCL4GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package, providing 330 µF capacitance at 10 V. It is engineered for applications that require low ESR, high ripple current handling and broad temperature operation.

With AEC-Q200 qualification and RoHS compliance, this part is positioned for demanding electronics, including automotive applications, where long life and stable performance across −55 °C to 105 °C are required.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance rated at 10 V with tolerance -20%~20% for predictable bulk energy storage and decoupling.
• Low ESR — ESR of 14 mΩ measured at 20 °C / 100 kHz, supporting efficient power delivery and heat management in high-frequency circuits.
• High Ripple Current — Supports 2.0 A at 120 Hz (low frequency) and 4.0 A at 100 kHz (high frequency), enabling use in converters and power rails with significant AC content.
• Solid Conductive Polymer Construction — Polymer electrolyte provides stable electrical characteristics and lower loss (tan δ = 0.12 at 20 °C, 120 Hz, 10 V).
• Temperature and Endurance — Operates from −55 °C to 105 °C with a load life of 2000 hours at 105 °C.
• SMD Radial Can Package — Compact φ8 × 12 mm body with surface mount land size 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Quality and Compliance — AEC-Q200 qualified and RoHS compliant as documented in the product information.

Typical Applications

• Automotive Electronics — Suitable for automotive systems where AEC-Q200 qualification and extended temperature range support reliable power decoupling and energy storage.
• Power Supply Filtering — Low ESR and high ripple current capability make it effective for smoothing and decoupling in DC–DC converters and power rails.
• High-Frequency Circuits — 14 mΩ ESR at 100 kHz and 4.0 A HF ripple current capacity support use in high-frequency switching applications.

Unique Advantages

• High ripple tolerance: Rated for 2.0 A at 120 Hz and 4.0 A at 100 kHz, enabling robust performance under AC loading conditions.
• Low dissipation at high frequency: 14 mΩ ESR at 100 kHz reduces losses and thermal rise in tight power budgets.
• Wide operating temperature: −55 °C to 105 °C operation accommodates harsh environments and maintains capacitance stability.
• Long load life: 2000 hours at 105 °C endurance supports designs with extended operating life requirements.
• SMD-friendly packaging: Embossed carrier taping and moisture-proof packing streamline automated PCB assembly and handling.
• Industry qualification: AEC-Q200 rating and RoHS compliance provide traceable quality and environmental conformity for regulated markets.
