PCW0G331MCO1GS

The PCW0G331MCO1GS is a conductive polymer aluminum solid electrolytic capacitor in a chip-style, surface-mount can from Nichicon’s PCW series. It is designed for applications that require high-temperature reliability, low ESR and high ripple-current capability.

Targeted use cases include automotive and communication electronics where AEC-Q200 qualification, extended temperature operation and robust reflow compatibility are required. The device delivers a compact SMD package with specifications tuned for high thermal and electrical stress environments.

Key Features

• Capacitance & Voltage — 330 µF capacitance rated at 4 V with ±20% tolerance, providing substantial bulk energy storage in a compact footprint.
• High-temperature endurance — Qualified for operation from −55 °C to +125 °C with a ripple load life of 2000 hours at 125 °C.
• Low ESR & High ripple handling — ESR of 16 mΩ at 100 kHz and ripple current ratings of 900 mA (120 Hz) and 1.8 A (100 kHz) to support demanding power-conditioning roles.
• Package & mounting — Chip-type surface-mount can (radial, can - SMD) with footprint recommendations of 6.6 × 6.6 mm and physical dimensions L: 6 × D: 6.3 mm; maximum seated height 6 mm.
• Assembly compatibility — Lead-free reflow soldering compatible with a peak temperature of up to 260 °C per the PCW series soldering conditions.
• Qualification & compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and automotive-grade designs.

Typical Applications

• Automotive electronics — Bulk and decoupling capacitance in control modules where AEC-Q200 qualification and 125 °C endurance are required.
• Communication equipment — Power conditioning and filtering in communications hardware that benefits from low ESR and high ripple-current capability.
• High-reliability industrial systems — Embedded power subsystems operating across wide temperature ranges that require long ripple-load life.

Unique Advantages

• High-temperature reliability: Rated for −55 °C to +125 °C with a 2000-hour ripple-load life at 125 °C, supporting designs that must withstand sustained elevated temperatures.
• Low ESR for efficient power handling: 16 mΩ ESR at 100 kHz combined with specified ripple-current ratings reduces losses and helps maintain stable voltage under load.
• Automotive-capable qualification: AEC-Q200 qualification provides documented reliability for automotive system integration.
• Reflow-friendly SMD can: Designed for lead-free reflow up to 260 °C peak, enabling modern assembly processes without special handling.
• Compact footprint: Small L: 6 × D: 6.3 mm package and 6.6 × 6.6 mm land pattern recommendation save PCB area while delivering substantial capacitance.
