GYE1V391MCQ1GS

The GYE1V391MCQ1GS is a conductive polymer hybrid aluminum electrolytic capacitor in the Nichicon GYE series designed for high-reliability, high-temperature board-level power applications. As a chip-type surface-mount radial can, it combines high capacitance with low equivalent series resistance (ESR) to support demanding power filtering and decoupling tasks.

Key value comes from a 390 µF capacitance at 35 V, a wide operating temperature range (−55 °C to +125 °C), low ESR (16 mΩ at 100 kHz) and high ripple-current capability, together with long-term endurance established by a 4,000 hour life at 125 °C. The part is AEC-Q200 qualified and RoHS compliant.

Key Features

• Electrical Capacity — 390 µF nominal capacitance at 35 V rated voltage, offering substantial bulk energy storage for board-level power rails.
• Low ESR & High Ripple Handling — ESR of 16 mΩ (100 kHz, 20 °C) with high-frequency ripple current rating of 3.5 A at 100 kHz and 525 mA at 120 Hz for improved thermal and electrical performance in high-ripple environments.
• High-Temperature Endurance — Rated for continuous operation from −55 °C to +125 °C with a guaranteed lifetime of 4,000 hours at 125 °C under rated conditions.
• Reliability & Qualification — AEC-Q200 qualified with endurance, damp heat and soldering heat characteristics specified in the series datasheet.
• Surface-Mount Package — Chip-type radial can in an SMD package (L: 1.25 cm × D: 1.0 cm) optimized for board-level installation; recommended land size L: 1.03 cm × W: 1.03 cm.
• Regulatory Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and 125 °C endurance make this capacitor suitable for vehicle electronic modules that require high ripple handling and long-term reliability.
• High-Temperature Power Supplies — Suited for board-level bulk filtering and smoothing in power supplies and converters that operate at elevated ambient temperatures up to 125 °C.
• High-Ripple DC Power Circuits — Low ESR and specified ripple current ratings support use in high-frequency switching and high-ripple applications requiring stable capacitance under stress.

Unique Advantages

• Long High-Temperature Life: 4,000 hours at 125 °C provides predictable ageing and endurance for designs exposed to sustained elevated temperatures.
• High Ripple Capacity with Low Loss: 16 mΩ ESR at 100 kHz and 3.5 A ripple rating at 100 kHz reduce heating and improve efficiency in high-frequency power stages.
• Broad Temperature Range: −55 °C to +125 °C operation supports applications across harsh thermal environments without additional derating assumptions.
• Board-Level SMD Form Factor: Chip-type radial can and defined land footprint simplify placement and reflow-compatible assembly for compact power designs.
• Industry Qualification & Compliance: AEC-Q200 qualification plus RoHS compliance helps meet regulatory and reliability requirements in regulated markets.
