PCF0J681MCL1GS

The PCF0J681MCL1GS is a chip-type conductive polymer aluminum solid electrolytic capacitor in an SMD can package. It delivers high capacitance (680 µF) at a low rated voltage (6.3 V) with low ESR and high ripple-current capability for demanding power decoupling and filtering tasks.

Designed for rugged environments, this part supports a wide temperature range (−55 °C to +105 °C), AEC-Q200 qualification, and a 2000-hour endurance rating at 105 °C, making it suitable for automotive and other high-reliability electronics where low impedance and long life are required.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20% for bulk energy storage and decoupling in low-voltage systems.
• Low ESR and High Ripple Handling — ESR of 14 mΩ measured at 100 kHz and high-frequency ripple current of 5.0 A (100 kHz) plus 2.5 A at 120 Hz, enabling efficient smoothing and transient handling in power circuits.
• Conductive Polymer Dielectric — Solid polymer construction provides low loss (tan δ = 0.12 at 20 °C, 120 Hz) and stable impedance across temperature for improved power integrity.
• Temperature and Endurance — Operating range from −55 °C to +105 °C with a rated load life of 2000 hours at 105 °C, delivering predictable performance for long-term deployments.
• Leakage and Reliability — Specified leakage current of 857 µA and endurance/damp-heat specifications that limit capacitance and ESR change to defined tolerances after qualification tests.
• SMD Packaging and Assembly — Chip-type radial can SMD package, size φ10 × 10L, supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering (peak surface temperature up to 260 °C as specified).
• Standards and Compliance — AEC-Q200 qualified and RoHS compliant for use in regulated and automotive applications.

Typical Applications

• Automotive power electronics — Used in vehicle power modules and electronic control units where low ESR, high ripple current capability and AEC-Q200 qualification are required.
• DC–DC converters — Bulk and output filtering in low-voltage converters benefitting from high capacitance and low impedance at high frequency.
• Power supply smoothing — Local energy storage and transient suppression for boards and modules operating across −55 °C to +105 °C.

Unique Advantages

• High ripple-current capacity: Rated for 5.0 A at 100 kHz and 2.5 A at 120 Hz, enabling smaller arrays or fewer parts for the same ripple-handling requirement.
• Low ESR: 14 mΩ at 100 kHz reduces power loss and heating in high-current designs, improving efficiency and thermal margin.
• Long-term thermal endurance: 2000 hours at 105 °C gives designers predictable lifetime performance in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 rating and RoHS compliance support use in regulated automotive systems and other applications demanding qualified components.
• SMD convenience with robust assembly: Embossed carrier taping and compatibility with lead-free reflow profiles simplify automated placement and soldering processes.
