PCF0J681MCL9GS

The PCF0J681MCL9GS is a Nichicon conductive polymer aluminum solid electrolytic capacitor in an SMD can package, offering 680 µF capacitance at a 6.3 V rating. It is designed for high-ripple, low-ESR power applications where long life and wide temperature operation are required.

Built to the PCF series specification, this part targets power-smoothing and decoupling roles in automotive and industrial electronic systems, combining low ESR and high ripple-current capability with AEC‑Q200 qualification and RoHS compliance.

Key Features

• Conductive polymer dielectric Solid electrolyte construction for stable performance and improved ripple handling compared to traditional electrolytes.
• Low ESR and high-frequency performance ESR of 10 mΩ measured at 20 °C, 100 kHz supports efficient filtering in high-frequency converter stages.
• High ripple-current capability Rated ripple currents of 2.75 A at 120 Hz and 5.5 A at 100 kHz accommodate heavy switching and power delivery demands.
• Compact SMD can package Case size φ10 × 12.7 L (L: 1.27 cm × D: 1.00 cm) with surface-mount land guidance simplifies PCB layout for dense designs.
• Wide temperature and endurance Operates from −55 °C to +105 °C with a rated load life of 2000 hours at 105 °C.
• Electrical characteristics 680 µF ±20% capacitance, tanδ 0.12 (20 °C, 120 Hz), and leakage current 857 µA (specified condition).
• Automotive-grade and environmental compliance AEC‑Q200 qualification and RoHS compliance for regulated market requirements.
• Soldering and assembly SMD reflow compatibility per PCF series guidance (peak reflow allowance up to 260 °C under specified conditions) and supplied in embossed carrier taping with moisture-proof packing.

Typical Applications

• Automotive power rails Bulk decoupling and smoothing on ECU and control-module power supplies where AEC‑Q200 qualification and temperature endurance are required.
• DC–DC converters Input/output filtering and energy buffering in high-switching-frequency converters, leveraging low ESR and high ripple capability.
• Infotainment and ADAS electronics Stable power delivery for noise-sensitive analog and digital subsystems across wide operating temperatures.
• Industrial power modules High-ripple filtering and local energy storage in motor drives, power supplies, and control systems demanding long life at elevated temperatures.

Unique Advantages

• Low loss at high frequency: 10 mΩ ESR at 100 kHz reduces heat generation and improves converter efficiency.
• Handles heavy ripple loads: Specified ripple currents (2.75 A @120 Hz, 5.5 A @100 kHz) support demanding switching environments.
• Robust thermal endurance: Rated for −55 °C to +105 °C and 2000 hours at 105 °C for sustained high-temperature operation.
• Automotive-ready qualification: AEC‑Q200 status supports integration into automotive electronic subsystems.
• SMD form factor with moisture protection: Embossed carrier taping and moisture-proof packing streamline automated assembly and handling.
• Regulatory compliance: RoHS compliance for environmentally regulated designs.
