PCJ0E681MCL1GS

The PCJ0E681MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor offering 680 µF capacitance at a 2.5 V rating. It is designed as a surface-mount, low-ESR solution for demanding environments, with features targeted at automotive electronics and other high-reliability systems.

Key value comes from its low equivalent series resistance (ESR), high ripple-current capability and extended load life at elevated temperature, enabling tighter power-rail decoupling and improved thermal reliability in compact SMD assemblies.

Key Features

• Dielectric & Core Conductive polymer aluminum solid electrolytic construction for stable capacitance and low ESR.
• Capacitance & Voltage 680 µF nominal capacitance with a 2.5 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low ESR ESR of 13 mΩ measured at 100 kHz (20°C), supporting efficient high-frequency decoupling.
• High Ripple Current Rated ripple current of 2.05 A at 120 Hz and 4.1 A at 100 kHz for handling AC stress on power rails.
• Temperature & Lifetime Operating range −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Package & Mounting Surface-mount radial can (chip type) with footprint land size 8.3 × 8.3 mm and compact case dimensions L: 7 × D: 8 mm.
• Solderability & Process SMD type compatible with lead-free reflow soldering conditions up to a 260°C peak (single reflow at ≤260°C per datasheet guidance).
• Compliance & Qualification RoHS compliant and AEC-Q200 qualified for automotive-grade reliability.

Typical Applications

• Automotive Electronics — Suited for electronic modules in automotive systems where AEC-Q200 qualification and wide temperature range are required.
• Surface-Mount Power Modules — Compact SMD package and lead-free reflow compatibility for automated assembly in dense board layouts.
• High-Ripple Power Rails — Low ESR and measured ripple-current ratings make it appropriate for smoothing and decoupling on high-stress power lines.

Unique Advantages

• Low ESR for improved transient response: 13 mΩ at 100 kHz reduces voltage droop on fast switching rails, aiding regulator stability.
• High ripple-current handling: 4.1 A at 100 kHz (4.1 A) and 2.05 A at 120 Hz provide headroom for AC stress and thermal management.
• Automotive-grade qualification: AEC-Q200 qualification supports deployment in automotive electronics and other high-reliability applications.
• Extended elevated-temperature life: Rated 2000 hours at 105°C, enabling long service life under sustained thermal load.
• Assembly-friendly SMD design: Chip-style radial can and lead-free reflow compatibility at up to 260°C simplify manufacturing integration.
• Regulatory compliance: RoHS-compliant construction for global environmental requirements.
