PCF0G331MCL1GS

The PCF0G331MCL1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor delivering 330 µF at 4 V. It combines low ESR and high ripple-current capability in a compact φ8 × 7 mm SMD can tailored for demanding printed-circuit board power systems.

Designed for environments that require extended endurance and temperature stability, this capacitor is AEC-Q200 qualified and RoHS compliant, making it suitable for automotive and other high-reliability applications where sustained performance at elevated temperature is required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 4 V for energy storage and decoupling in low-voltage power rails.
• Low ESR / High-Frequency Performance — ESR of 21 mΩ measured at 100 kHz (20°C) and tanδ of 0.12 (20°C, 120 Hz), delivering efficient high-frequency filtering and reduced power loss.
• High Ripple Current Capability — Low-frequency ripple current of 1.7 A (120 Hz) and high-frequency ripple current of 3.4 A (100 kHz) to handle dynamic current transients and converter output filtering.
• Leakage and Stability — Specified leakage current of 264 µA (measurement condition: 2 minutes application at 20°C), supporting predictable bias behavior in long-running systems.
• Temperature and Endurance — Operating range –55°C to +105°C with a rated load life of 2000 hours at 105°C, suitable for sustained elevated-temperature operation.
• Package & Assembly — Compact φ8 × 7 mm SMD radial can in embossed carrier taping with moisture-proof packing; compatible with lead‑free reflow soldering (peak correspondence up to 260°C per series soldering guidance).
• Quality & Compliance — AEC-Q200 qualification and RoHS compliance for regulated and automotive-focused designs.

Typical Applications

• Power Supply Decoupling — Use as bulk and decoupling capacitance on low-voltage regulator outputs to reduce ripple and stabilize converters thanks to low ESR and high ripple-current ratings.
• DC–DC Converter Output Filtering — Suited for converter outputs where high-frequency ripple attenuation and high ripple current handling are required.
• Automotive Electronics — Applicable in automotive modules that require AEC-Q200‑level components and sustained operation up to 105°C.

Unique Advantages

• High ripple-current endurance: 3.4 A at 100 kHz and 1.7 A at 120 Hz provide margin for dynamic loads and switching converter outputs.
• Low effective series resistance: 21 mΩ ESR at 100 kHz minimizes I²R losses and thermal rise in high-current circuits.
• Compact SMD footprint: φ8 × 7 mm can and defined land size (8.3 × 8.3 mm) save PCB area while delivering substantial capacitance.
• Designed for elevated-temperature service: Rated for –55°C to +105°C with 2000-hour endurance at 105°C for dependable long-term performance.
• Automotive-ready qualification: AEC-Q200 status supports use in regulated automotive electronics and other high-reliability systems.
• Manufacturing compatibility: Embossed carrier taping and moisture-proof packing streamline pick-and-place and reflow assembly processes.
