GYC1V331MCW1GS

The GYC1V331MCW1GS is a surface-mount conductive polymer hybrid aluminum electrolytic capacitor from Nichicon’s GYC series, designed for high-reliability power applications. It combines high capacitance (330 µF) and a 35 V rating with low ESR and elevated ripple-current capability for robust performance in demanding environments.

Built for long-term operation at elevated temperatures and qualified to AEC-Q200, this part targets automotive and other high-reliability systems where temperature endurance, low loss and compact SMD packaging are required.

Key Features

• Capacitance & Voltage: 330 µF rated at 35 V for bulk energy storage and decoupling in compact SMD form.
• Low ESR & High-Frequency Performance: ESR of 16 mΩ measured at 20°C/100 kHz, supporting high-frequency decoupling and fast transient response.
• High Ripple Current Capability: 345 mA at 120 Hz (low frequency) and 2.3 A at 100 kHz (high frequency) to handle significant AC ripple on power rails.
• Wide Temperature Range & Long Life: Operates from −55°C to +135°C with an endurance rating of 4000 hours at 135°C for extended high-temperature reliability.
• Electrical Characteristics: Tangent of loss angle (tan δ) 0.12 at 35 V (120 Hz, 20°C) and specified leakage current of 115.5 µA.
• Package & Mounting: Surface-mount radial can (φ10 × 12.5 L) in embossed carrier taping for automated assembly.
• Automotive Qualification & Compliance: AEC-Q200 rated and RoHS compliant, supporting use in regulated environments.

Typical Applications

• Automotive Power Systems: Energy storage and smoothing for DC–DC converters and electronic control modules, leveraging the high ripple current and 135°C endurance.
• Power Supply Decoupling: Bulk decoupling and transient support on high-frequency power rails where low ESR and high ripple handling are required.
• Industrial Power Electronics: Filtering and energy buffering in compact, high-temperature industrial controllers and power stages.

Unique Advantages

• High-Temperature Endurance: Rated to −55°C to +135°C with 4000-hour life at 135°C, enabling reliable operation in hot environments and extended duty cycles.
• Low Loss at High Frequency: 16 mΩ ESR at 100 kHz and 0.12 tan δ at 35 V (120 Hz, 20°C) reduce heating and improve efficiency in switching applications.
• Robust Ripple Handling: 2.3 A ripple current at 100 kHz supports demanding AC ripple conditions in modern power converters.
• Automotive-Grade Qualification: AEC-Q200 rating provides documented qualification for automotive and high-reliability system integration.
• SMD Packaging for Automated Assembly: Embossed carrier taping and compact φ10 × 12.5 mm can simplify PCB integration and high-volume placement.
• Regulatory Compliance: RoHS compliant for use in regulated production environments.
