PCK0E391MCO1GS

The PCK0E391MCO1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package. It delivers high capacitance (390 µF) at a low rated voltage (2.5 V) while offering ultra‑low ESR for demanding power applications.

Designed and qualified for automotive use, this AEC‑Q200 rated capacitor provides high ripple current capability and a 2000‑hour load life at 105°C, making it suitable for compact, high‑reliability electronics assemblies that require robust decoupling and energy buffering.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance at a rated voltage of 2.5 V with ±20% tolerance for stable bulk energy storage in low‑voltage systems.
• Ultra‑low ESR & High Ripple Handling — ESR of 10 mΩ measured at 100 kHz and rated ripple currents of 3.9 A (100 kHz) and 1.95 A (120 Hz) for improved voltage stability and thermal performance under ripple stress.
• Temperature Range & Lifetime — Specified operating range of −55°C to +105°C with a rated load life of 2000 hours at 105°C, supporting long‑term operation in elevated temperature environments.
• Package & Mounting — Surface‑mount radial can (SMD) with compact dimensions (L: 6 × D: 6.3 mm) and a recommended land size of 6.6 × 6.6 mm for space‑constrained board designs.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant, supporting use in regulated automotive electronics and eco‑conscious manufacturing.
• Assembly Compatibility — SMD type designed for lead‑free reflow soldering with a peak correspondence up to 260°C per the series specification.

Typical Applications

• Automotive electronic modules — Energy buffering and decoupling in automotive control modules where AEC‑Q200 qualification and extended high‑temperature life are required.
• Power rail smoothing — Local bulk capacitance and ripple suppression on low‑voltage power rails that demand low ESR and high ripple current capability.
• Compact SMD designs — High capacitance in a small footprint for space‑limited assemblies that benefit from surface‑mount installation and lead‑free reflow compatibility.

Unique Advantages

• High energy density in a small package: 390 µF in a 6 × 6.3 mm SMD can provides significant bulk capacitance where PCB space is limited.
• Improved power integrity: 10 mΩ ESR at 100 kHz combined with high ripple current ratings minimizes voltage drop and reduces thermal rise under ripple loads.
• Automotive‑grade reliability: AEC‑Q200 qualification and a 2000‑hour life at 105°C support long‑term operation in harsh thermal environments.
• RoHS compliant and reflow capable: Lead‑free reflow soldering compatibility (260°C peak correspondence) simplifies modern assembly processes while meeting environmental directives.
• Wide operating temperature: −55°C to +105°C operation ensures consistent performance across typical automotive temperature extremes.
