PCK0E681MCO1GS

The PCK0E681MCO1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It delivers a 680 µF capacitance at 2.5 V with ultra-low ESR and high ripple-current capability for demanding power applications.

Designed and qualified for automotive use (AEC-Q200) and compliant with RoHS, this capacitor targets applications that require high ripple handling, long life at elevated temperature, and compact SMD packaging for efficient board-level integration.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance with a rated voltage of 2.5 V and tolerance of ±20% (–20% to +20%).
• Ultra-low ESR — 9 mΩ equivalent series resistance measured at 100 kHz and 20°C, supporting fast transient response and reduced power loss.
• High Ripple Current — Rated ripple currents of 2.25 A at 120 Hz and 4.5 A at 100 kHz to support sustained AC stress and high-frequency filtering.
• Long Endurance — Load life specified as 2000 hours at 105°C, maintaining capacitance, tan δ and ESR within defined limits after endurance testing.
• Wide Temperature Range — Operating from –55°C to +105°C to accommodate a broad range of environmental conditions.
• Surface Mount, Compact Package — Radial can SMD package with body dimensions L: 7 × D: 8 mm and recommended land size L: 8.3 × W: 8.3 mm for PCB layout efficiency.
• Standards and Manufacturing — AEC-Q200 qualified and RoHS compliant; SMD lead-free reflow soldering conditions support 260°C peak reflow capability as specified.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and high ripple-current capability make this capacitor suited for automotive electronic modules that require durable power decoupling and filtering.
• Power Supply Filtering — Ultra-low ESR and high-frequency ripple handling (4.5 A at 100 kHz) support local bulk and decoupling functions on compact power rails.
• High-Temperature Environments — Rated for continuous operation up to 105°C with a 2000 hour load-life, suitable for applications where elevated ambient temperatures are expected.

Unique Advantages

• Low-loss performance: 9 mΩ ESR at 100 kHz reduces ripple-related losses and improves thermal behavior in dense power designs.
• High ripple tolerance: Specified ripple currents at both 120 Hz and 100 kHz enable reliable operation across low- and high-frequency power domains.
• Automotive-grade qualification: AEC-Q200 rating provides documented suitability for automotive electronics development and deployment.
• Compact SMD form factor: Small 7 × 8 mm footprint and recommended land pattern simplify board integration while preserving capacitance density.
• Long elevated-temperature life: 2000 hours at 105°C offers endurance for designs exposed to sustained high temperatures.
• RoHS compliant manufacturing: Meets RoHS requirements for environmentally compliant assemblies.
