PCW0J221MCO1GS

The PCW0J221MCO1GS is a Nichicon conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount applications that require high ripple tolerance and elevated temperature reliability. It combines low ESR and high ripple-current capability in a compact SMD can package for demanding electronics environments.

Targeted use cases include automotive-grade power systems and other electronic designs that need robust bulk smoothing and decoupling on power rails, especially where operation to 125°C and AEC-Q200 qualification are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a rated voltage of 6.3 V with ±20% tolerance for stable bulk energy storage.
• Low ESR — 16 mΩ equivalent series resistance (ESR) measured at 100 kHz, supporting efficient power delivery and reduced losses.
• High Ripple Current — Rated for 900 mA at 120 Hz and 1.8 A at 100 kHz to handle switching and ripple currents in DC–DC converters and power stages.
• High Temperature Endurance — Operates from −55 °C to +125 °C with a ripple load life of 2000 hours at 125 °C, providing extended reliability under elevated operating temperatures.
• Surface-Mount Package — Chip-type radial can SMD with compact footprint (L: 6 × D: 6.3 mm) and recommended land size 6.6 × 6.6 mm for PCB integration.
• Assembly Compatibility — Lead-free reflow soldering compatible with a 260 °C peak temperature reflow profile (single reflow at ≤260 °C as specified).
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, supporting use in regulated and automotive-related applications.

Typical Applications

• Automotive Power Electronics — Bulk smoothing and decoupling in automotive ECUs and power modules where AEC-Q200 qualification and 125 °C operation are required.
• DC–DC Converter Outputs — Output filtering for switching converters that demand low ESR and high ripple-current handling to minimize voltage ripple and dissipation.
• Infotainment & Communication Modules — Local energy storage and ripple suppression in communication and infotainment subsystems operating at elevated temperatures.

Unique Advantages

• Robust high‑temperature endurance: Rated for 2000 hours at 125 °C, enabling longer service life in hot environments.
• High ripple capability with low loss: 1.8 A (100 kHz) ripple rating combined with 16 mΩ ESR reduces thermal stress and improves power-stage efficiency.
• Automotive-grade qualification: AEC-Q200 status supports use in designs requiring automotive reliability standards.
• SMD-friendly assembly: Lead-free reflow compatibility up to 260 °C simplifies integration into standard surface-mount production flows.
• Compact footprint: Small 6 × 6.3 mm can footprint and defined land pattern support high-density PCB layouts.
