PCF0G821MCL1GS

The PCF0G821MCL1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 820 µF capacitance at a 4 V rating. Designed as an SMD radial can, it delivers low ESR and high ripple current handling in a compact φ10 × 10 mm package.

Targeted for demanding environments, this part combines AEC-Q200 qualification, wide operating temperature range and long load life to support reliable power filtering and decoupling in automotive and industrial electronics.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance at a 4 V rated voltage with tolerance of -20% to +20%.
• Low ESR — 13 mΩ ESR measured at 20°C, 100 kHz, minimizing losses and heat generation under high-frequency switching.
• High Ripple Current — Rated for 2.4 A at 120 Hz (low frequency) and 4.8 A at 100 kHz (high frequency), enabling effective smoothing of switching regulator outputs.
• Thermal and Endurance Performance — Load life of 2000 hours at 105°C and operating temperature range from -55°C to +105°C.
• Leakage and Loss — Leakage current specified at 656 µA and tanδ (DF) of 0.12 measured at 20°C, 120 Hz, supporting stable behavior in precision power applications.
• Package & Mounting — Surface-mount radial can, size φ10 × 10 mm (L: 1 × D: 1 cm) with embossed carrier taping and moisture-proof packing for automated assembly.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant for regulated production environments.

Typical Applications

• Automotive power electronics — Local energy storage and smoothing for DC–DC converters and power modules, leveraging high ripple current capability and low ESR.
• Automotive control modules — Decoupling and bulk capacitance in electronic control units that require AEC-Q200 qualification and extended temperature endurance (-55°C to +105°C).
• Infotainment and body electronics — Voltage stabilization and transient absorption in systems where compact SMD packaging and long life at elevated temperatures are required.

Unique Advantages

• High ripple tolerance: 4.8 A at 100 kHz and 2.4 A at 120 Hz reduces the need for parallel capacitors in high-frequency power rails.
• Low ESR for efficiency: 13 mΩ ESR at 100 kHz lowers conduction losses and thermal stress in switching applications.
• Automotive-grade qualification: AEC-Q200 status supports use in automotive electronic systems requiring standardized reliability.
• Extended temperature and endurance: Rated for -55°C to +105°C with a 2000-hour life at 105°C, providing predictable long-term performance in harsh environments.
• Assembly-ready SMD format: φ10 × 10 mm surface-mount can with embossed carrier taping and moisture-proof packing simplifies high-volume PCB assembly.
• Regulatory compliance: RoHS compliant for global production requirements.
