PCA1J680MCL1GS

The PCA1J680MCL1GS from Nichicon is a conductive-polymer aluminum solid electrolytic capacitor in the PCA series designed for high-reliability power applications. It is a surface-mount, radial can package offering 68 µF capacitance at a 63 V rating.

Engineered for demanding environments, this part delivers low ESR and high ripple current capability along with a wide operating temperature range and AEC‑Q200 qualification, making it suitable for automotive and other high-reliability systems that require long life and stable performance at elevated temperatures.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low ESR — ESR specified at 27 mΩ (100 kHz, 20°C) for improved power-stage efficiency and reduced loss in high-frequency applications.
• High Ripple Current — Rated for 3.7 A at 100 kHz and 1.85 A at 120 Hz, supporting heavy AC/RF ripple in power conversion and filtering circuits.
• Extended Temperature & Life — Operating range from -55°C to +125°C with a life rating of 4000 hours at 125°C under rated conditions.
• Reliability & Qualification — AEC‑Q200 compliant and designed for endurance with ESR verified after endurance at -40°C.
• SMD Assembly Compatible — Radial can, SMD package constructed for lead-free reflow soldering up to a 260°C peak profile (pre-heating and reflow conditions per datasheet).
• Package & Board Pattern — Compact footprint: 12 mm × 8 mm overall size (L × D) with a recommended surface-mount land size of 8.3 mm × 8.3 mm.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Power Electronics — Bulk filtering and decoupling in electronic control units and power modules where 125°C operation and AEC‑Q200 qualification are required.
• DC–DC Converters — Output and intermediate bus capacitors for converters that demand low ESR and high ripple-current handling at high switching frequencies.
• Motor Drive & Power Modules — Smoothing and ripple absorption in inverter and drive stages exposed to elevated temperatures and sustained ripple currents.
• Industrial Power Systems — Reliable decoupling in harsh-environment power supplies and controllers that require long endurance and stable impedance across temperature.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 3.7 A (100 kHz) and 1.85 A (120 Hz) reduce the need for parallel devices in high-power designs.
• Low-loss operation: 27 mΩ ESR at 100 kHz lowers conduction losses and helps maintain thermal margin in dense power assemblies.
• Wide temperature endurance: -55°C to +125°C range and 4000-hour life at 125°C support long-term reliability in thermally demanding environments.
• Automotive-ready qualification: AEC‑Q200 compliance supports usage in regulated automotive electronics and other high-reliability applications.
• SMD radial can form factor: Compact footprint with a defined land pattern (8.3 mm × 8.3 mm) simplifies PCB layout for space-constrained power designs.
• Lead-free reflow compatibility: Supports lead-free reflow profiles up to 260°C peak for modern assembly processes.
